Auxin plays a central role in mediating root gravitropism, but how auxin contributes to gravitational perception and the subsequent response is still unclear.\r\n\r\nHere, we showed that the local auxin maximum/gradient within the root apex, which is generated by the PIN directional auxin transporters, regulates the expression of three key starch granule synthesis genes, SS4, PGM and ADG1, which in turn influence the accumulation of starch granules that serve as a statolith perceiving gravity.\r\n\r\nMoreover, using the cvxIAA‐ccvTIR1 system, we also showed that TIR1‐mediated auxin signaling is required for starch granule formation and gravitropic response within root tips. 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.

Here, we measured the effects of a set of Bacillus subtilis glutamate dehydrogenase mutants across 19 different environments—from phenotypically homogeneous single-cell populations in liquid media to heterogeneous biofilms, plant roots and soil populations. The effects of individual gene mutations on organismal fitness were highly reproducible in liquid cultures. However, 84% of the tested alleles showed opposing fitness effects under different growth conditions (sign environmental pleiotropy). In colony biofilms and soil samples, different alleles dominated in parallel replica experiments. Accordingly, we found that in these heterogeneous cell populations the fate of mutations was dictated by a combination of selection and drift. The latter relates to programmed prophage excisions that occurred during biofilm development. Overall, for each condition, a wide range of glutamate dehydrogenase mutations persisted and sometimes fixated as a result of the combined action of selection, pleiotropy and chance. However, over longer periods and in multiple environments, nearly all of this diversity would be lost—across all the environments and conditions that we tested, the wild type was the fittest allele. article_processing_charge: No article_type: original author: - first_name: Lianet full_name: Noda-García, Lianet last_name: Noda-García - first_name: Dan full_name: Davidi, Dan last_name: Davidi - first_name: Elisa full_name: Korenblum, Elisa last_name: Korenblum - first_name: Assaf full_name: Elazar, Assaf last_name: Elazar - first_name: Ekaterina full_name: Putintseva, Ekaterina id: 2EF67C84-F248-11E8-B48F-1D18A9856A87 last_name: Putintseva - first_name: Asaph full_name: Aharoni, Asaph last_name: Aharoni - first_name: Dan S. full_name: Tawfik, Dan S. last_name: Tawfik citation: ama: Noda-García L, Davidi D, Korenblum E, et al.

Genetic manipulation of microglia can elucidate their functional impact in disease. In neuroscience, recombinant viruses such as lentiviruses and adeno-associated viruses (AAVs) have been successfully used to target various cell types in the brain, although effective transduction of microglia is rare. In this review, we provide a short background of lentiviruses and AAVs, and strategies for designing recombinant viral vectors. Then, we will summarize recent literature on successful microglial transductions in vitro and in vivo, and discuss the current challenges. Finally, we provide guidelines for reporting the efficiency and specificity of viral targeting in microglia, which will enable the microglial research community to assess and improve methodologies for future studies. article_number: '134310' article_processing_charge: No article_type: original author: - first_name: Margaret E full_name: Maes, Margaret E id: 3838F452-F248-11E8-B48F-1D18A9856A87 last_name: Maes orcid: 0000-0001-9642-1085 - first_name: Gloria full_name: Colombo, Gloria id: 3483CF6C-F248-11E8-B48F-1D18A9856A87 last_name: Colombo orcid: 0000-0001-9434-8902 - first_name: Rouven full_name: Schulz, Rouven id: 4C5E7B96-F248-11E8-B48F-1D18A9856A87 last_name: Schulz orcid: 0000-0001-5297-733X - first_name: Sandra full_name: Siegert, Sandra id: 36ACD32E-F248-11E8-B48F-1D18A9856A87 last_name: Siegert orcid: 0000-0001-8635-0877 citation: ama: 'Maes ME, Colombo G, Schulz R, Siegert S.

Although fetal LGR5-expressing cells can give rise to adult intestinal stem cells3,4, it remains unclear whether this population in the patterned epithelium represents unique intestinal stem-cell precursors. Here we show, using unbiased quantitative lineage-tracing approaches, biophysical modelling and intestinal transplantation, that all cells of the mouse intestinal epithelium—irrespective of their location and pattern of LGR5 expression in the fetal gut tube—contribute actively to the adult intestinal stem cell pool. Using 3D imaging, we find that during fetal development the villus undergoes gross remodelling and fission. This brings epithelial cells from the non-proliferative villus into the proliferative intervillus region, which enables them to contribute to the adult stem-cell niche. Our results demonstrate that large-scale remodelling of the intestinal wall and cell-fate specification are closely linked. Moreover, these findings provide a direct link between the observed plasticity and cellular reprogramming of differentiating cells in adult tissues following damage5,6,7,8,9, revealing that stem-cell identity is an induced rather than a hardwired property. article_processing_charge: No article_type: original author: - first_name: Jordi full_name: Guiu, Jordi last_name: Guiu - first_name: Edouard B full_name: Hannezo, Edouard B id: 3A9DB764-F248-11E8-B48F-1D18A9856A87 last_name: Hannezo orcid: 0000-0001-6005-1561 - first_name: Shiro full_name: Yui, Shiro last_name: Yui - first_name: Samuel full_name: Demharter, Samuel last_name: Demharter - first_name: Svetlana full_name: Ulyanchenko, Svetlana last_name: Ulyanchenko - first_name: Martti full_name: Maimets, Martti last_name: Maimets - first_name: Anne full_name: Jørgensen, Anne last_name: Jørgensen - first_name: Signe full_name: Perlman, Signe last_name: Perlman - first_name: Lene full_name: Lundvall, Lene last_name: Lundvall - first_name: Linn Salto full_name: Mamsen, Linn Salto last_name: Mamsen - first_name: Agnete full_name: Larsen, Agnete last_name: Larsen - first_name: Rasmus H. full_name: Olesen, Rasmus H. last_name: Olesen - first_name: Claus Yding full_name: Andersen, Claus Yding last_name: Andersen - first_name: Lea Langhoff full_name: Thuesen, Lea Langhoff last_name: Thuesen - first_name: Kristine Juul full_name: Hare, Kristine Juul last_name: Hare - first_name: Tune H. full_name: Pers, Tune H. last_name: Pers - first_name: Konstantin full_name: Khodosevich, Konstantin last_name: Khodosevich - first_name: Benjamin D. full_name: Simons, Benjamin D. last_name: Simons - first_name: Kim B. full_name: Jensen, Kim B. last_name: Jensen citation: ama: Guiu J, Hannezo EB, Yui S, et al.

Many optogenetic tools are driven by light-controlled protein–protein interactions (PPIs) that are repurposed from natural light-sensitive domains (LSDs). Applying light-controlled PPIs to new target proteins is challenging because it is difficult to predict which of the many available LSDs, if any, will yield robust light regulation. As a consequence, fusion protein libraries need to be prepared and tested, but methods and platforms to facilitate this process are currently not available. Here, we developed a genetic engineering strategy and vector library for the rapid generation of light-controlled PPIs. The strategy permits fusing a target protein to multiple LSDs efficiently and in two orientations. The public and expandable library contains 29 vectors with blue, green or red light-responsive LSDs, many of which have been previously applied ex vivo and in vivo. We demonstrate the versatility of the approach and the necessity for sampling LSDs by generating light-activated caspase-9 (casp9) enzymes. Collectively, this work provides a new resource for optical regulation of a broad range of target proteins in cell and developmental biology. article_processing_charge: No article_type: original author: - first_name: Alexandra-Madelaine full_name: Tichy, Alexandra-Madelaine id: 29D8BB2C-F248-11E8-B48F-1D18A9856A87 last_name: Tichy - first_name: Elliot J. full_name: Gerrard, Elliot J. last_name: Gerrard - first_name: Julien M.D. full_name: Legrand, Julien M.D. last_name: Legrand - first_name: Robin M. full_name: Hobbs, Robin M. last_name: Hobbs - first_name: Harald L full_name: Janovjak, Harald L id: 33BA6C30-F248-11E8-B48F-1D18A9856A87 last_name: Janovjak orcid: 0000-0002-8023-9315 citation: ama: Tichy A-M, Gerrard EJ, Legrand JMD, Hobbs RM, Janovjak HL.
