--- _id: '1640' abstract: - lang: eng text: Auxin and cytokinin are key endogenous regulators of plant development. Although cytokinin-mediated modulation of auxin distribution is a developmentally crucial hormonal interaction, its molecular basis is largely unknown. Here we show a direct regulatory link between cytokinin signalling and the auxin transport machinery uncovering a mechanistic framework for cytokinin-auxin cross-talk. We show that the CYTOKININ RESPONSE FACTORS (CRFs), transcription factors downstream of cytokinin perception, transcriptionally control genes encoding PIN-FORMED (PIN) auxin transporters at a specific PIN CYTOKININ RESPONSE ELEMENT (PCRE) domain. Removal of this cis-regulatory element effectively uncouples PIN transcription from the CRF-mediated cytokinin regulation and attenuates plant cytokinin sensitivity. We propose that CRFs represent a missing cross-talk component that fine-tunes auxin transport capacity downstream of cytokinin signalling to control plant development. acknowledged_ssus: - _id: Bio - _id: LifeSc acknowledgement: This work was supported by the European Research Council Starting Independent Research grant (ERC-2007-Stg-207362-HCPO to E.B., M.S., C.C.), by the Ghent University Multidisciplinary Research Partnership ‘Biotechnology for a Sustainable Economy’ no.01MRB510W, by the Research Foundation—Flanders (grant 3G033711 to J.-A.O.), by the Austrian Science Fund (FWF01_I1774S) to K.Ö.,E.B., and by the Interuniversity Attraction Poles Programme (IUAP P7/29 ‘MARS’) initiated by the Belgian Science Policy Office.

Cell expansion requires ordered arrangement of the cytoskeleton but molecular mechanisms underlying its regulation by signalling molecules including auxin are unknown. Here we show in the model plant Arabidopsis thaliana that in elongating cells exogenous application of auxin or redistribution of endogenous auxin induces very rapid microtubule re-orientation from transverse to longitudinal, coherent with the inhibition of cell expansion. This fast auxin effect requires auxin binding protein 1 (ABP1) and involves a contribution of downstream signalling components such as ROP6 GTPase, ROP-interactive protein RIC1 and the microtubule-severing protein katanin. These components are required for rapid auxin-and ABP1-mediated re-orientation of microtubules to regulate cell elongation in roots and dark-grown hypocotyls as well as asymmetric growth during gravitropic responses. acknowledgement: We thank R.

Here, we endeavoured to clarify the function of brassinosteroids (BRs) and cross-talk with ethylene in hook development. An automated infrared imaging system was developed to study the kinetics of hook development in etiolated Arabidopsis seedlings. To ascertain the photomorphogenic control of hook opening, the system was equipped with an automatic light dimmer. We demonstrate that ethylene and BRs are indispensable for hook formation and maintenance. Ethylene regulation of hook formation functions partly through BRs, with BR feedback inhibition of ethylene action. Conversely, BR-mediated extension of hook maintenance functions partly through ethylene. Furthermore, we revealed that a short light pulse is sufficient to induce rapid hook opening. Our dynamic infrared imaging system allows high-resolution, kinetic imaging of up to 112 seedlings in a single experimental run. At this high throughput, it is ideally suited to rapidly gain insight in pathway networks. We demonstrate that BRs and ethylene cooperatively regulate apical hook development in a phase-dependent manner. Furthermore, we show that light is a predominant regulator of hook opening, inhibiting ethylene- and BR-mediated postponement of hook opening. acknowledgement: 'Funded by Ghent University; Research Foundation Flanders Grant Number: G065613N European Research Council Grant Number: CZ.1.07/2.3.00/20.0043' author: - first_name: Dajo full_name: Smet, Dajo last_name: Smet - first_name: Petra full_name: Žádníková, Petra last_name: Žádníková - first_name: Filip full_name: Vandenbussche, Filip last_name: Vandenbussche - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Dominique full_name: Van Der Straeten, Dominique last_name: Van Der Straeten citation: ama: 'Smet D, Žádníková P, Vandenbussche F, Benková E, Van Der Straeten D.

Cytokinin-mediated modulation of auxin transport provides an efficient means to regulate auxin distribution in plant organs. Here, we demonstrate that cytokinin does not merely control the overall auxin flow capacity, but might also act as a polarizing cue and control the auxin stream directionality during plant organogenesis. Cytokinin enhances the PIN-FORMED1 (PIN1) auxin transporter depletion at specific polar domains, thus rearranging the cellular PIN polarities and directly regulating the auxin flow direction. This selective cytokinin sensitivity correlates with the PIN protein phosphorylation degree. PIN1 phosphomimicking mutations, as well as enhanced phosphorylation in plants with modulated activities of PIN-specific kinases and phosphatases, desensitize PIN1 to cytokinin. Our results reveal conceptually novel, cytokinin-driven polarization mechanism that operates in developmental processes involving rapid auxin stream redirection, such as lateral root organogenesis, in which a gradual PIN polarity switch defines the growth axis of the newly formed organ. author: - first_name: Peter full_name: Marhavy, Peter id: 3F45B078-F248-11E8-B48F-1D18A9856A87 last_name: Marhavy orcid: 0000-0001-5227-5741 - first_name: Jérôme full_name: Duclercq, Jérôme last_name: Duclercq - first_name: Benjamin full_name: Weller, Benjamin last_name: Weller - first_name: Elena full_name: Feraru, Elena last_name: Feraru - first_name: Agnieszka full_name: Bielach, Agnieszka last_name: Bielach - first_name: Remko full_name: Offringa, Remko last_name: Offringa - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Claus full_name: Schwechheimer, Claus last_name: Schwechheimer - first_name: Angus full_name: Murphy, Angus last_name: Murphy - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 citation: ama: Marhavý P, Duclercq J, Weller B, et al.

However, the cells establishing these gradients during microspore embryogenesis remain to be identified. For the first time, we describe, using the DR5 or DR5rev reporter gene systems, the GFP- and GUS-based auxin biosensors to monitor auxin during Brassica napus androgenesis at cellular resolution in the initial stages. Our study provides evidence that the distribution of auxin changes during embryo development and depends on the temperature-inducible in vitro culture conditions. For this, microspores (mcs) were induced to embryogenesis by heat treatment and then subjected to genetic modification via Agrobacterium tumefaciens. The duration of high temperature treatment had a significant influence on auxin distribution in isolated and in vitro-cultured microspores and on microspore-derived embryo development. In the “mild” heat-treated (1 day at 32 °C) mcs, auxin localized in a polar way already at the uni-nucleate microspore, which was critical for the initiation of embryos with suspensor-like structure. Assuming a mean mcs radius of 20 μm, endogenous auxin content in a single cell corresponded to concentration of 1.01 μM. In mcs subjected to a prolonged heat (5 days at 32 °C), although auxin concentration increased dozen times, auxin polarization was set up at a few-celled pro-embryos without suspensor. Those embryos were enclosed in the outer wall called the exine. The exine rupture was accompanied by the auxin gradient polarization. Relative quantitative estimation of auxin, using time-lapse imaging, revealed that primordia possess up to 1.3-fold higher amounts than those found in the root apices of transgenic MDEs in the presence of exogenous auxin. Our results show, for the first time, which concentration of endogenous auxin coincides with the first cell division and how the high temperature interplays with auxin, by what affects delay early establishing microspore polarity. Moreover, we present how the local auxin accumulation demonstrates the apical–basal axis formation of the androgenic embryo and directs the axiality of the adult haploid plant. acknowledgement: The research was supported by the IPP PAS-IPGB SAS bilateral project (“Molecular analysis of auxin distribution in oilseed androgenic embryos”), IPP PAS-FWO VIB bilateral project (“Auxin as signaling molecule in doubled haploid production of rape (B. napus var. oleifera)”), individual national research project 2011/01/D/NZ9/02547, and VEGA 2-0090-14. author: - first_name: Ewa full_name: Dubas, Ewa last_name: Dubas - first_name: Jana full_name: Moravčíková, Jana last_name: Moravčíková - first_name: Jana full_name: Libantová, Jana last_name: Libantová - first_name: Ildikó full_name: Matušíková, Ildikó last_name: Matušíková - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Iwona full_name: Zur, Iwona last_name: Zur - first_name: Monika full_name: Krzewska, Monika last_name: Krzewska citation: ama: Dubas E, Moravčíková J, Libantová J, et al.

The present study addresses the phylogenetic position of the Balkan endemic Ranunculus wettsteinii, as well as its taxonomic status and relationship with the widespread R. parnassiifolius, based on nuclear DNA (internal transcribed spacer, ITS) and plastid regions (rpl32-trnL, rps16-trnQ, trnK-matK and ycf6-psbM). Maximum parsimony and Bayesian inference analyses revealed a well-supported clade formed by accessions of R. wettsteinii. Furthermore, our phylogenetic and network analyses supported previous hypotheses of a likely allopolyploid origin for R. wettsteinii between R. montenegrinus and R. parnassiifolius, with the latter as the maternal parent. article_processing_charge: No author: - first_name: Eduardo full_name: Cires Rodriguez, Eduardo id: 2AD56A7A-F248-11E8-B48F-1D18A9856A87 last_name: Cires Rodriguez - first_name: Matthias full_name: Baltisberger, Matthias last_name: Baltisberger - first_name: Candela full_name: Cuesta, Candela id: 33A3C818-F248-11E8-B48F-1D18A9856A87 last_name: Cuesta orcid: 0000-0003-1923-2410 - first_name: Pablo full_name: Vargas, Pablo last_name: Vargas - first_name: José full_name: Prieto, José last_name: Prieto citation: ama: Cires Rodriguez E, Baltisberger M, Cuesta C, Vargas P, Prieto J.

The Arabidopsis PIN protein family has been shown to play important roles in developmental processes such as embryogenesis, organogenesis, vascular tissue differentiation, root meristem patterning and tropic growth. Here we analyzed roles of the less characterised Arabidopsis PIN6 auxin transporter. PIN6 is auxin-inducible and is expressed during multiple auxin-regulated developmental processes. Loss of pin6 function interfered with primary root growth and lateral root development. Misexpression of PIN6 affected auxin transport and interfered with auxin homeostasis in other growth processes such as shoot apical dominance, lateral root primordia development, adventitious root formation, root hair outgrowth and root waving. These changes in auxin-regulated growth correlated with a reduction in total auxin transport as well as with an altered activity of DR5-GUS auxin response reporter. Overall, the data indicate that PIN6 regulates auxin homeostasis during plant development. article_number: e70069 author: - first_name: Christopher full_name: Cazzonelli, Christopher last_name: Cazzonelli - first_name: Marleen full_name: Vanstraelen, Marleen last_name: Vanstraelen - first_name: Sibu full_name: Simon, Sibu id: 4542EF9A-F248-11E8-B48F-1D18A9856A87 last_name: Simon orcid: 0000-0002-1998-6741 - first_name: Kuide full_name: Yin, Kuide last_name: Yin - first_name: Ashley full_name: Carron Arthur, Ashley last_name: Carron Arthur - first_name: Nazia full_name: Nisar, Nazia last_name: Nisar - first_name: Gauri full_name: Tarle, Gauri last_name: Tarle - first_name: Abby full_name: Cuttriss, Abby last_name: Cuttriss - first_name: Iain full_name: Searle, Iain last_name: Searle - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Ulrike full_name: Mathesius, Ulrike last_name: Mathesius - first_name: Josette full_name: Masle, Josette last_name: Masle - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Barry full_name: Pogson, Barry last_name: Pogson citation: ama: Cazzonelli C, Vanstraelen M, Simon S, et al.

Whereas mechanisms of positive and negative orthogravitropism of primary roots and shoots are relatively well understood [1-3], lateral organs often show more complex growth behavior [4]. Lateral roots (LRs) seemingly suppress positive gravitropic growth and show a defined gravitropic set-point angle (GSA) that allows radial expansion of the root system (plagiotropism) [3, 4]. Despite its eminent importance for root architecture, it so far remains completely unknown how lateral organs partially suppress positive orthogravitropism. Here we show that the phytohormone auxin steers GSA formation and limits positive orthogravitropism in LR. Low and high auxin levels/signaling lead to radial or axial root systems, respectively. At a cellular level, it is the auxin transport-dependent regulation of asymmetric growth in the elongation zone that determines GSA. Our data suggest that strong repression of PIN4/PIN7 and transient PIN3 expression limit auxin redistribution in young LR columella cells. We conclude that PIN activity, by temporally limiting the asymmetric auxin fluxes in the tip of LRs, induces transient, differential growth responses in the elongation zone and, consequently, controls root architecture. author: - first_name: Michel full_name: Rosquete, Michel last_name: Rosquete - first_name: Daniel full_name: Von Wangenheim, Daniel id: 49E91952-F248-11E8-B48F-1D18A9856A87 last_name: Von Wangenheim orcid: 0000-0002-6862-1247 - first_name: Peter full_name: Marhavy, Peter id: 3F45B078-F248-11E8-B48F-1D18A9856A87 last_name: Marhavy orcid: 0000-0001-5227-5741 - first_name: Elke full_name: Barbez, Elke last_name: Barbez - first_name: Ernst full_name: Stelzer, Ernst last_name: Stelzer - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Alexis full_name: Maizel, Alexis last_name: Maizel - first_name: Jürgen full_name: Kleine Vehn, Jürgen last_name: Kleine Vehn citation: ama: Rosquete M, von Wangenheim D, Marhavý P, et al.

How this auxin maximum in pericycle cells builds up and remains focused is not understood. We report that the endodermis plays an active role in the regulation of auxin accumulation and is instructive for FCs to progress during the LR initiation (LRI) phase. We describe the functional importance of a PIN3 (PIN-formed) auxin efflux carrier-dependent hormone reflux pathway between overlaying endodermal and pericycle FCs. Disrupting this reflux pathway causes dramatic defects in the progress of FCs towards the next initiation phase. Our data identify an unexpected regulatory function for the endodermis in LRI as part of the fine-tuning mechanism that appears to act as a check point in LR organogenesis after FCs are specified. author: - first_name: Peter full_name: Marhavy, Peter id: 3F45B078-F248-11E8-B48F-1D18A9856A87 last_name: Marhavy orcid: 0000-0001-5227-5741 - first_name: Marleen full_name: Vanstraelen, Marleen last_name: Vanstraelen - first_name: Bert full_name: De Rybel, Bert last_name: De Rybel - first_name: Ding full_name: Zhaojun, Ding last_name: Zhaojun - first_name: Malcolm full_name: Bennett, Malcolm last_name: Bennett - first_name: Tom full_name: Beeckman, Tom last_name: Beeckman - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 citation: ama: Marhavý P, Vanstraelen M, De Rybel B, et al.

To establish a polarized embryonic axis, plants evolved a unique mechanism that involves directional, cell-to-cell transport of the growth regulator auxin. Auxin transport relies on PIN auxin transporters [1], whose polar subcellular localization determines the flow directionality. PIN-mediated auxin transport mediates the spatial and temporal activity of the auxin response machinery [2-7] that contributes to embryo patterning processes, including establishment of the apical (shoot) and basal (root) embryo poles [8]. However, little is known of upstream mechanisms guiding the (re)polarization of auxin fluxes during embryogenesis [9]. Here, we developed a model of plant embryogenesis that correctly generates emergent cell polarities and auxin-mediated sequential initiation of apical-basal axis of plant embryo. The model relies on two precisely localized auxin sources and a feedback between auxin and the polar, subcellular PIN transporter localization. Simulations reproduced PIN polarity and auxin distribution, as well as previously unknown polarization events during early embryogenesis. The spectrum of validated model predictions suggests that our model corresponds to a minimal mechanistic framework for initiation and orientation of the apical-basal axis to guide both embryonic and postembryonic plant development. author: - first_name: Krzysztof T full_name: Wabnik, Krzysztof T id: 4DE369A4-F248-11E8-B48F-1D18A9856A87 last_name: Wabnik orcid: 0000-0001-7263-0560 - first_name: Hélène full_name: Robert, Hélène last_name: Robert - first_name: Richard full_name: Smith, Richard last_name: Smith - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Wabnik KT, Robert H, Smith R, Friml J.

Plants that perceive some of these changes as stress signals activate signaling pathways to modulate their development and to enable them to survive. The complex responses to environmental cues are to a large extent mediated by plant hormones that together orchestrate the final plant response. The phytohormone cytokinin is involved in many plant developmental processes. Recently, it has been established that cytokinin plays an important role in stress responses, but does not act alone. Indeed, the hormonal control of plant development and stress adaptation is the outcome of a complex network of multiple synergistic and antagonistic interactions between various hormones. Here, we review the recent findings on the cytokinin function as part of this hormonal network. We focus on the importance of the crosstalk between cytokinin and other hormones, such as abscisic acid, jasmonate, salicylic acid, ethylene, and auxin in the modulation of plant development and stress adaptation. Finally, the impact of the current research in the biotechnological industry will be discussed. article_number: '451' author: - first_name: José full_name: O'Brien, José last_name: O'Brien - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 citation: ama: O’Brien J, Benková E.

It is a dynamic organ modulated by external cues such as environmental signals, water and nutrients availability, salinity and others. Lateral roots (LRs) are initiated from the primary root post-embryonically, after which they progress through discrete developmental stages which can be independently controlled, providing a high level of plasticity during root system formation. Within this review, main contributions are presented, from the classical forward genetic screens to the more recent high-throughput approaches, combined with computer model predictions, dissecting how LRs and thereby root system architecture is established and developed. article_number: '537' author: - first_name: Candela full_name: Cuesta, Candela id: 33A3C818-F248-11E8-B48F-1D18A9856A87 last_name: Cuesta orcid: 0000-0003-1923-2410 - first_name: Krzysztof T full_name: Wabnik, Krzysztof T id: 4DE369A4-F248-11E8-B48F-1D18A9856A87 last_name: Wabnik orcid: 0000-0001-7263-0560 - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 citation: ama: Cuesta C, Wabnik KT, Benková E.
