Spontaneously arising channels transporting the phytohormone auxin, created by coordinated polar localizations of PIN-FORMED 1 (PIN1) auxin exporter, provide positional cues for these as well as other plant patterning processes. To find regulators acting downstream of auxin and the TIR1/AFB auxin signaling pathway essential for PIN1 coordinated polarization during auxin canalization, we performed microarray experiments. Besides the known components of general PIN polarity maintenance, such as PID and PIP5K kinases, we identified and characterized a new regulator of auxin canalization, the transcription factor WRKY DNA-BINDING PROTEIN 23 (WRKY23).\r\nNext, we designed a subsequent microarray experiment to further uncover other molecular players, downstream of auxin-TIR1/AFB-WRKY23 involved in the regulation of auxin-mediated PIN repolarization. We identified a novel and crucial part of the molecular machinery underlying auxin canalization. The auxin-regulated malectin-type receptor-like kinase CAMEL and the associated leucine-rich repeat receptor-like kinase CANAR target and directly phosphorylate PIN auxin transporters. camel and canar mutants are impaired in PIN1 subcellular trafficking and auxin-mediated repolarization leading to defects in auxin transport, ultimately to leaf venation and vasculature regeneration defects. Our results describe the CAMEL-CANAR receptor complex, which is required for auxin feed-back on its own transport and thus for coordinated tissue polarization during auxin canalization." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Jakub full_name: Hajny, Jakub id: 4800CC20-F248-11E8-B48F-1D18A9856A87 last_name: Hajny orcid: 0000-0003-2140-7195 citation: ama: Hajny J.

Nonetheless, the evolutionary origin of their unprecedented morphological complexity remains largely an enigma. Here, we show that the coevolution of cis-regulatory and coding regions of PIN-FORMED (PIN) auxin transporters confined their expression to certain cell types and directed their subcellular localization to particular cell sides, which together enabled dynamic auxin gradients across tissues critical to the complex architecture of flowering plants. Extensive intraspecies and interspecies genetic complementation experiments with PINs from green alga up to flowering plant lineages showed that PIN genes underwent three subsequent, critical evolutionary innovations and thus acquired a triple function to regulate the development of three essential components of the flowering plant Arabidopsis: shoot/root, inflorescence, and floral organ. Our work highlights the critical role of functional innovations within the PIN gene family as essential prerequisites for the origin of flowering plants.' acknowledgement: 'We thank C.Löhne (Botanic Gardens, University of Bonn) for providing us with A. trichopoda.

MYB transcription factors play a crucial role in plants’ biological processes, but the function of pineapple MYB genes is still obscure. In this study, one of the pineapple MYB transcription factors, AcoMYB4, was isolated and characterized. The results showed that AcoMYB4 is localized in the cell nucleus, and its expression is induced by low temperature, drought, salt stress, and hormonal stimulation, especially by abscisic acid (ABA). Overexpression of AcoMYB4 in rice and Arabidopsis enhanced plant sensitivity to osmotic stress; it led to an increase in the number stomata on leaf surfaces and lower germination rate under salt and drought stress. Furthermore, in AcoMYB4 OE lines, the membrane oxidation index, free proline, and soluble sugar contents were decreased. In contrast, electrolyte leakage and malondialdehyde (MDA) content increased significantly due to membrane injury, indicating higher sensitivity to drought and salinity stresses. Besides the above, both the expression level and activities of several antioxidant enzymes were decreased, indicating lower antioxidant activity in AcoMYB4 transgenic plants. Moreover, under osmotic stress, overexpression of AcoMYB4 inhibited ABA biosynthesis through a decrease in the transcription of genes responsible for ABA synthesis (ABA1 and ABA2) and ABA signal transduction factor ABI5. These results suggest that AcoMYB4 negatively regulates osmotic stress by attenuating cellular ABA biosynthesis and signal transduction pathways.

MCS connections enable the nonvesicular exchange of information between organelles and allow them to coordinate responses to changing cellular environments. In plants, the importance of MCS components in the responses to environmental stress has been widely established, but the molecular mechanisms regulating interorganelle connectivity during stress still remain opaque. In this report, we use the model plant Arabidopsis thaliana to show that ionic stress increases endoplasmic reticulum (ER)–plasma membrane (PM) connectivity by promoting the cortical expansion of synaptotagmin 1 (SYT1)-enriched ER–PM contact sites (S-EPCSs). We define differential roles for the cortical cytoskeleton in the regulation of S-EPCS dynamics and ER–PM connectivity, and we identify the accumulation of phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2] at the PM as a molecular signal associated with the ER–PM connectivity changes. Our study highlights the functional conservation of EPCS components and PM phosphoinositides as modulators of ER–PM connectivity in eukaryotes, and uncovers unique aspects of the spatiotemporal regulation of ER–PM connectivity in plants. article_processing_charge: No article_type: original author: - first_name: Eunkyoung full_name: Lee, Eunkyoung last_name: Lee - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Jessica full_name: Pérez-Sancho, Jessica last_name: Pérez-Sancho - first_name: Francisco full_name: Benitez-Fuente, Francisco last_name: Benitez-Fuente - first_name: Matthew full_name: Strelau, Matthew last_name: Strelau - first_name: Alberto P. full_name: Macho, Alberto P. last_name: Macho - first_name: Miguel A. full_name: Botella, Miguel A. last_name: Botella - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Abel full_name: Rosado, Abel last_name: Rosado citation: ama: Lee E, Vanneste S, Pérez-Sancho J, et al.

In plants, it is unknown how cell polarities are connected to organismal axes and translated to division. Here, we identify Arabidopsis SOSEKI proteins that integrate apical–basal and radial organismal axes to localize to polar cell edges. Localization does not depend on tissue context, requires cell wall integrity and is defined by a transferrable, protein-specific motif. A Domain of Unknown Function in SOSEKI proteins resembles the DIX oligomerization domain in the animal Dishevelled polarity regulator. The DIX-like domain self-interacts and is required for edge localization and for influencing division orientation, together with a second domain that defines the polar membrane domain. Our work shows that SOSEKI proteins locally interpret global polarity cues and can influence cell division orientation. Furthermore, this work reveals that, despite fundamental differences, cell polarity mechanisms in plants and animals converge on a similar protein domain. article_processing_charge: No author: - first_name: Saiko full_name: Yoshida, Saiko id: 2E46069C-F248-11E8-B48F-1D18A9856A87 last_name: Yoshida - first_name: Alja full_name: Van Der Schuren, Alja last_name: Van Der Schuren - first_name: Maritza full_name: Van Dop, Maritza last_name: Van Dop - first_name: Luc full_name: Van Galen, Luc last_name: Van Galen - first_name: Shunsuke full_name: Saiga, Shunsuke last_name: Saiga - first_name: Milad full_name: Adibi, Milad last_name: Adibi - first_name: Barbara full_name: Möller, Barbara last_name: Möller - first_name: Colette A. full_name: Ten Hove, Colette A. last_name: Ten Hove - first_name: Peter full_name: Marhavy, Peter id: 3F45B078-F248-11E8-B48F-1D18A9856A87 last_name: Marhavy orcid: 0000-0001-5227-5741 - first_name: Richard full_name: Smith, Richard last_name: Smith - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Dolf full_name: Weijers, Dolf last_name: Weijers citation: ama: Yoshida S, Van Der Schuren A, Van Dop M, et al.

On a molecular level, stress conditions result in elevation of reactive oxygen species (ROS) production causing oxidative stress associated with oxidation of proteins and nucleic acids as well as impairment of membrane functions. Adaptation of root growth to ROS accumulation is facilitated through modification of auxin and cytokinin hormone homeostasis. Here, we report that in Arabidopsis root meristem, ROS-induced changes of auxin levels correspond to decreased abundance of PIN auxin efflux carriers at the plasma membrane (PM). Specifically, increase in H2O2 levels affects PIN2 endocytic recycling. We show that the PIN2 intracellular trafficking during adaptation to oxidative stress requires the function of the ADP-ribosylation factor (ARF)-guanine-nucleotide exchange factor (GEF) BEN1, an actin-associated regulator of the trafficking from the PM to early endosomes and, presumably, indirectly, trafficking to the vacuoles. We propose that H2O2 levels affect the actin dynamics thus modulating ARF-GEF-dependent trafficking of PIN2. This mechanism provides a way how root growth acclimates to stress and adapts to a changing environment. article_processing_charge: No author: - first_name: Marta full_name: Zwiewka, Marta last_name: Zwiewka - first_name: Agnieszka full_name: Bielach, Agnieszka last_name: Bielach - first_name: Prashanth full_name: Tamizhselvan, Prashanth last_name: Tamizhselvan - first_name: Sharmila full_name: Madhavan, Sharmila last_name: Madhavan - first_name: Eman Elrefaay full_name: Ryad, Eman Elrefaay last_name: Ryad - first_name: Shutang full_name: Tan, Shutang id: 2DE75584-F248-11E8-B48F-1D18A9856A87 last_name: Tan orcid: 0000-0002-0471-8285 - first_name: Mónika full_name: Hrtyan, Mónika id: 45A71A74-F248-11E8-B48F-1D18A9856A87 last_name: Hrtyan - first_name: Petre full_name: Dobrev, Petre last_name: Dobrev - first_name: Radomira full_name: Vanková, Radomira last_name: Vanková - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Vanesa B. full_name: Tognetti, Vanesa B. last_name: Tognetti citation: ama: Zwiewka M, Bielach A, Tamizhselvan P, et al.

In addition, axr3 mutants showed reduced auxin‐mediated starch granule accumulation and disruption of gravitropism within the root apex.\r\n\r\nOur results indicate that auxin‐mediated statolith production relies on the TIR1/AFB‐AXR3‐mediated auxin signaling pathway. In summary, we propose a dual role for auxin in gravitropism: the regulation of both gravity perception and response." article_processing_charge: No article_type: original author: - first_name: Yuzhou full_name: Zhang, Yuzhou id: 3B6137F2-F248-11E8-B48F-1D18A9856A87 last_name: Zhang orcid: 0000-0003-2627-6956 - first_name: P full_name: He, P last_name: He - first_name: X full_name: Ma, X last_name: Ma - first_name: Z full_name: Yang, Z last_name: Yang - first_name: C full_name: Pang, C last_name: Pang - first_name: J full_name: Yu, J last_name: Yu - first_name: G full_name: Wang, G last_name: Wang - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: G full_name: Xiao, G last_name: Xiao citation: ama: Zhang Y, He P, Ma X, et al.

Despite its importance, the regulation of PIN polar subcellular localization remains poorly understood. Here, we have employed advanced live-cell imaging techniques to study the roles of microtubules and actin microfilaments in the establishment of apical polar localization of PIN2 in the epidermis of the Arabidopsis root meristem.

Increased elongation growth of roots, hypocotyls and petioles in warm temperatures are hallmarks of seedling thermomorphogenesis. In the last decade, significant progress has been made to identify the molecular signaling components regulating these growth responses. Increased ambient temperature utilizes diverse components of the light sensing and signal transduction network to trigger growth adjustments. However, it remains unknown whether temperature sensing and responses are universal processes that occur uniformly in all plant organs. Alternatively, temperature sensing may be confined to specific tissues or organs, which would require a systemic signal that mediates responses in distal parts of the plant. Here we show that Arabidopsis (Arabidopsis thaliana) seedlings show organ-specific transcriptome responses to elevated temperatures, and that thermomorphogenesis involves both autonomous and organ-interdependent temperature sensing and signaling. Seedling roots can sense and respond to temperature in a shoot-independent manner, whereas shoot temperature responses require both local and systemic processes. The induction of cell elongation in hypocotyls requires temperature sensing in cotyledons, followed by generation of a mobile auxin signal. Subsequently, auxin travels to the hypocotyl where it triggers local brassinosteroid-induced cell elongation in seedling stems, which depends upon a distinct, permissive temperature sensor in the hypocotyl. article_processing_charge: No article_type: original author: - first_name: Julia full_name: Bellstaedt, Julia last_name: Bellstaedt - first_name: Jana full_name: Trenner, Jana last_name: Trenner - first_name: Rebecca full_name: Lippmann, Rebecca last_name: Lippmann - first_name: Yvonne full_name: Poeschl, Yvonne last_name: Poeschl - first_name: Xixi full_name: Zhang, Xixi id: 61A66458-47E9-11EA-85BA-8AEAAF14E49A last_name: Zhang orcid: 0000-0001-7048-4627 - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Marcel full_name: Quint, Marcel last_name: Quint - first_name: Carolin full_name: Delker, Carolin last_name: Delker citation: ama: Bellstaedt J, Trenner J, Lippmann R, et al.

Concentrations of auxin vary across different tissues, mediating distinct developmental outcomes and contributing to the functional diversity of auxin. However, the mechanisms that underlie these activities are poorly understood. Here we identify an auxin signalling mechanism, which acts in parallel to the canonical auxin pathway based on the transport inhibitor response1 (TIR1) and other auxin receptor F-box (AFB) family proteins (TIR1/AFB receptors)1,2, that translates levels of cellular auxin to mediate differential growth during apical-hook development. This signalling mechanism operates at the concave side of the apical hook, and involves auxin-mediated C-terminal cleavage of transmembrane kinase 1 (TMK1). The cytosolic and nucleus-translocated C terminus of TMK1 specifically interacts with and phosphorylates two non-canonical transcriptional repressors of the auxin or indole-3-acetic acid (Aux/IAA) family (IAA32 and IAA34), thereby regulating ARF transcription factors. In contrast to the degradation of Aux/IAA transcriptional repressors in the canonical pathway, the newly identified mechanism stabilizes the non-canonical IAA32 and IAA34 transcriptional repressors to regulate gene expression and ultimately inhibit growth. The auxin–TMK1 signalling pathway originates at the cell surface, is triggered by high levels of auxin and shares a partially overlapping set of transcription factors with the TIR1/AFB signalling pathway. This allows distinct interpretations of different concentrations of cellular auxin, and thus enables this versatile signalling molecule to mediate complex developmental outcomes. article_processing_charge: No article_type: original author: - first_name: Min full_name: Cao, Min last_name: Cao - first_name: Rong full_name: Chen, Rong last_name: Chen - first_name: Pan full_name: Li, Pan last_name: Li - first_name: Yongqiang full_name: Yu, Yongqiang last_name: Yu - first_name: Rui full_name: Zheng, Rui last_name: Zheng - first_name: Danfeng full_name: Ge, Danfeng last_name: Ge - first_name: Wei full_name: Zheng, Wei last_name: Zheng - first_name: Xuhui full_name: Wang, Xuhui last_name: Wang - first_name: Yangtao full_name: Gu, Yangtao last_name: Gu - first_name: Zuzana full_name: Gelová, Zuzana id: 0AE74790-0E0B-11E9-ABC7-1ACFE5697425 last_name: Gelová orcid: 0000-0003-4783-1752 - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Heng full_name: Zhang, Heng last_name: Zhang - first_name: Renyi full_name: Liu, Renyi last_name: Liu - first_name: Jun full_name: He, Jun last_name: He - first_name: Tongda full_name: Xu, Tongda last_name: Xu citation: ama: Cao M, Chen R, Li P, et al.

To elucidate the evolutionary origins of this developmentally crucial mechanism, we analysed the single PIN homologue of a simple green alga Klebsormidium flaccidum. KfPIN functions as a plasma membrane-localized auxin exporter in land plants and heterologous models. While its role in algae remains unclear, PIN-driven auxin export is probably an ancient and conserved trait within streptophytes. article_processing_charge: No article_type: original author: - first_name: Roman full_name: Skokan, Roman last_name: Skokan - first_name: Eva full_name: Medvecká, Eva last_name: Medvecká - first_name: Tom full_name: Viaene, Tom last_name: Viaene - first_name: Stanislav full_name: Vosolsobě, Stanislav last_name: Vosolsobě - first_name: Marta full_name: Zwiewka, Marta last_name: Zwiewka - first_name: Karel full_name: Müller, Karel last_name: Müller - first_name: Petr full_name: Skůpa, Petr last_name: Skůpa - first_name: Michal full_name: Karady, Michal last_name: Karady - first_name: Yuzhou full_name: Zhang, Yuzhou last_name: Zhang - first_name: Dorina P. full_name: Janacek, Dorina P. last_name: Janacek - first_name: Ulrich Z. full_name: Hammes, Ulrich Z. last_name: Hammes - first_name: Karin full_name: Ljung, Karin last_name: Ljung - first_name: Tomasz full_name: Nodzyński, Tomasz last_name: Nodzyński - first_name: Jan full_name: Petrášek, Jan last_name: Petrášek - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Skokan R, Medvecká E, Viaene T, et al.

Both the pathogen and the plant are under high selective pressure to rapidly adapt and co-evolve in what is usually referred to as molecular arms race. Components of the host’s immune system form a network that processes information about molecules with a foreign origin and damage-associated signals, integrating them with developmental and abiotic cues to adapt the plant’s responses. Both in the case of nucleotide-binding leucine-rich repeat receptors and leucine-rich repeat receptor kinases interaction networks have been extensively characterized. However, little is known on whether pathogenic effectors form complexes to overcome plant immunity and promote disease. Ustilago maydis, a biotrophic fungal pathogen that infects maize plants, produces effectors that target hubs in the immune network of the host cell. Here we assess the capability of U. maydis effector candidates to interact with each other, which may play a crucial role during the infection process. Using a systematic yeast-two-hybrid approach and based on a preliminary pooled screen, we selected 63 putative effectors for one-on-one matings with a library of nearly 300 effector candidates. We found that 126 of these effector candidates interacted either with themselves or other predicted effectors. Although the functional relevance of the observed interactions remains elusive, we propose that the observed abundance in complex formation between effectors adds an additional level of complexity to effector research and should be taken into consideration when studying effector evolution and function. Based on this fundamental finding, we suggest various scenarios which could evolutionarily drive the formation and stabilization of an effector interactome. article_number: '1437' article_processing_charge: No article_type: original author: - first_name: André full_name: Alcântara, André last_name: Alcântara - first_name: Jason full_name: Bosch, Jason last_name: Bosch - first_name: Fahimeh full_name: Nazari, Fahimeh last_name: Nazari - first_name: Gesa full_name: Hoffmann, Gesa last_name: Hoffmann - first_name: Michelle C full_name: Gallei, Michelle C id: 35A03822-F248-11E8-B48F-1D18A9856A87 last_name: Gallei orcid: 0000-0003-1286-7368 - first_name: Simon full_name: Uhse, Simon last_name: Uhse - first_name: Martin A. full_name: Darino, Martin A. last_name: Darino - first_name: Toluwase full_name: Olukayode, Toluwase last_name: Olukayode - first_name: Daniel full_name: Reumann, Daniel last_name: Reumann - first_name: Laura full_name: Baggaley, Laura last_name: Baggaley - first_name: Armin full_name: Djamei, Armin last_name: Djamei citation: ama: Alcântara A, Bosch J, Nazari F, et al.

In contrast, although small molecules can acutely and reversibly perturb CME, the few chemical CME inhibitors that have been applied to plants are either ineffective or show undesirable side effects. Here, we identify the previously described endosidin9 (ES9) as an inhibitor of clathrin heavy chain (CHC) function in both Arabidopsis and human cells through affinity-based target isolation, in vitro binding studies and X-ray crystallography. Moreover, we present a chemically improved ES9 analog, ES9-17, which lacks the undesirable side effects of ES9 while retaining the ability to target CHC. ES9 and ES9-17 have expanded the chemical toolbox used to probe CHC function, and present chemical scaffolds for further design of more specific and potent CHC inhibitors across different systems. article_processing_charge: No article_type: original author: - first_name: Wim full_name: Dejonghe, Wim last_name: Dejonghe - first_name: Isha full_name: Sharma, Isha last_name: Sharma - first_name: Bram full_name: Denoo, Bram last_name: Denoo - first_name: Steven full_name: De Munck, Steven last_name: De Munck - first_name: Qing full_name: Lu, Qing last_name: Lu - first_name: Kiril full_name: Mishev, Kiril last_name: Mishev - first_name: Haydar full_name: Bulut, Haydar last_name: Bulut - first_name: Evelien full_name: Mylle, Evelien last_name: Mylle - first_name: Riet full_name: De Rycke, Riet last_name: De Rycke - first_name: Mina K full_name: Vasileva, Mina K id: 3407EB18-F248-11E8-B48F-1D18A9856A87 last_name: Vasileva - first_name: Daniel V. full_name: Savatin, Daniel V. last_name: Savatin - first_name: Wim full_name: Nerinckx, Wim last_name: Nerinckx - first_name: An full_name: Staes, An last_name: Staes - first_name: Andrzej full_name: Drozdzecki, Andrzej last_name: Drozdzecki - first_name: Dominique full_name: Audenaert, Dominique last_name: Audenaert - first_name: Klaas full_name: Yperman, Klaas last_name: Yperman - first_name: Annemieke full_name: Madder, Annemieke last_name: Madder - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Daniël full_name: Van Damme, Daniël last_name: Van Damme - first_name: Kris full_name: Gevaert, Kris last_name: Gevaert - first_name: Volker full_name: Haucke, Volker last_name: Haucke - first_name: Savvas N. full_name: Savvides, Savvas N. last_name: Savvides - first_name: Johan full_name: Winne, Johan last_name: Winne - first_name: Eugenia full_name: Russinova, Eugenia last_name: Russinova citation: ama: Dejonghe W, Sharma I, Denoo B, et al.

An important role in these processes play the phytohormones and among them, auxin is crucial as it controls many important functions. It is transported through the whole plant body by creating local and temporal concentration maxima and minima, which have an impact on the cell status, tissue and organ identity. Auxin has the property to undergo a directional and finely regulated cell-to-cell transport, which is enabled by the transport proteins, localized on the plasma membrane. An important role in this process have the PIN auxin efflux proteins, which have an asymmetric/polar subcellular localization and determine the directionality of the auxin transport. During the last years, there were significant advances in understanding how the trafficking molecular machineries function, including studies on molecular interactions, function, subcellular localization and intracellular distribution. However, there is still a lack of detailed characterization on the steps of endocytosis, exocytosis, endocytic recycling and degradation. Due to this fact, I focused on the identification of novel trafficking factors and better characterization of the intracellular trafficking pathways. My PhD thesis consists of an introductory chapter, three experimental chapters, a chapter containing general discussion, conclusions and perspectives and also an appendix chapter with published collaborative papers.\r\nThe first chapter is separated in two different parts: I start by a general introduction to auxin biology and then I introduce the trafficking pathways in the model plant Arabidopsis thaliana. Then, I explain also the phosphorylation-signals for polar targeting and also the roles of the phytohormone strigolactone.\r\nThe second chapter includes the characterization of bar1/sacsin mutant, which was identified in a forward genetic screen for novel trafficking components in Arabidopsis thaliana, where by the implementation of an EMS-treated pPIN1::PIN1-GFP marker line and by using the established inhibitor of ARF-GEFs, Brefeldin A (BFA) as a tool to study trafficking processes, we identified a novel factor, which is mediating the adaptation of the plant cell to ARF-GEF inhibition. The mutation is in a previously uncharacterized gene, encoding a very big protein that we, based on its homologies, called SACSIN with domains suggesting roles as a molecular chaperon or as a component of the ubiquitin-proteasome system. Our physiology and imaging studies revealed that SACSIN is a crucial plant cell component of the adaptation to the ARF-GEF inhibition.\r\nThe third chapter includes six subchapters, where I focus on the role of the phytohormone strigolactone, which interferes with auxin feedback on PIN internalization. Strigolactone moderates the polar auxin transport by increasing the internalization of the PIN auxin efflux carriers, which reduces the canalization related growth responses. In addition, I also studied the role of phosphorylation in the strigolactone regulation of auxin feedback on PIN internalization. In this chapter I also present my results on the MAX2-dependence of strigolactone-mediated root growth inhibition and I also share my results on the auxin metabolomics profiling after application of GR24.\r\nIn the fourth chapter I studied the effect of two small molecules ES-9 and ES9-17, which were identified from a collection of small molecules with the property to impair the clathrin-mediated endocytosis.\r\nIn the fifth chapter, I discuss all my observations and experimental findings and suggest alternative hypothesis to interpret my results.\r\nIn the appendix there are three collaborative published projects. In the first, I participated in the characterization of the role of ES9 as a small molecule, which is inhibitor of clathrin- mediated endocytosis in different model organisms. In the second paper, I contributed to the characterization of another small molecule ES9-17, which is a non-protonophoric analog of ES9 and also impairs the clathrin-mediated endocytosis not only in plant cells, but also in mammalian HeLa cells. Last but not least, I also attach another paper, where I tried to establish the grafting method as a technique in our lab to study canalization related processes." acknowledged_ssus: - _id: LifeSc - _id: Bio alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Mina K full_name: Vasileva, Mina K id: 3407EB18-F248-11E8-B48F-1D18A9856A87 last_name: Vasileva citation: ama: Vasileva MK.

Plant cells have evolved diverse mechanisms to regulate PD plasticity in response to numerous environmental stimuli. In particular, during defense against plant pathogens, the defense hormone, salicylic acid (SA), plays a crucial role in the regulation of PD permeability in a callose-dependent manner. Here, we uncover a mechanism by which plants restrict the spreading of virus and PD cargoes using SA signaling by increasing lipid order and closure of PD. We showed that exogenous SA application triggered the compartmentalization of lipid raft nanodomains through a modulation of the lipid raft-regulatory protein, Remorin (REM). Genetic studies, superresolution imaging, and transmission electron microscopy observation together demonstrated that Arabidopsis REM1.2 and REM1.3 are crucial for plasma membrane nanodomain assembly to control PD aperture and functionality. In addition, we also found that a 14-3-3 epsilon protein modulates REM clustering and membrane nanodomain compartmentalization through its direct interaction with REM proteins. This study unveils a molecular mechanism by which the key plant defense hormone, SA, triggers membrane lipid nanodomain reorganization, thereby regulating PD closure to impede virus spreading. article_processing_charge: No article_type: original author: - first_name: D full_name: Huang, D last_name: Huang - first_name: Y full_name: Sun, Y last_name: Sun - first_name: Z full_name: Ma, Z last_name: Ma - first_name: M full_name: Ke, M last_name: Ke - first_name: Y full_name: Cui, Y last_name: Cui - first_name: Z full_name: Chen, Z last_name: Chen - first_name: C full_name: Chen, C last_name: Chen - first_name: C full_name: Ji, C last_name: Ji - first_name: TM full_name: Tran, TM last_name: Tran - first_name: L full_name: Yang, L last_name: Yang - first_name: SM full_name: Lam, SM last_name: Lam - first_name: Y full_name: Han, Y last_name: Han - first_name: G full_name: Shu, G last_name: Shu - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Y full_name: Miao, Y last_name: Miao - first_name: L full_name: Jiang, L last_name: Jiang - first_name: X full_name: Chen, X last_name: Chen citation: ama: Huang D, Sun Y, Ma Z, et al.
