How independent organs achieve anisotropic shapes and polarities is poorly understood. To address this question, we constructed a mechano-biochemical model for Arabidopsis root meristem growth that integrates biologically plausible principles. Computer model simulations demonstrate how differential growth of neighboring tissues results in the initial symmetry-breaking leading to anisotropic root growth. Furthermore, the root growth feeds back on a polar transport network of the growth regulator auxin. Model, predictions are in close agreement with in vivo patterns of anisotropic growth, auxin distribution, and cell polarity, as well as several root phenotypes caused by chemical, mechanical, or genetic perturbations. Our study demonstrates that the combination of tissue mechanics and polar auxin transport organizes anisotropic root growth and cell polarities during organ outgrowth. Therefore, a mobile auxin signal transported through immobile cells drives polarity and growth mechanics to coordinate complex organ development. acknowledgement: 'e are grateful Richard Smith, Anne-Lise Routier, Crisanto Gutierrez and Juergen Kleine-Vehn for providing critical comments on the manuscript.

The phytohormone auxin is a vital growth regulator with central importance for differential growth control. Our results indicate that auxin-reliant growth programs affect the molecular complexity of xyloglucans, the major type of cell wall hemicellulose in eudicots. Auxin-dependent induction and repression of growth coincide with reduced and enhanced molecular complexity of xyloglucans, respectively. In agreement with a proposed function in growth control, genetic interference with xyloglucan side decorations distinctly modulates auxin-dependent differential growth rates. Our work proposes that auxin-dependent growth programs have a spatially defined effect on xyloglucan’s molecular structure, which in turn affects cell wall mechanics and specifies differential, gravitropic hypocotyl growth. acknowledgement: "We are grateful to Paul Knox, Markus Pauly, Malcom O’Neill, and Ignacio Zarra for providing published material; the BOKU-VIBT Imaging Center for access and M.

Flowering time is regulated at the level of gene expression by a complex network of factors that integrate environmental and developmental cues. One of the main players, involved in modulating flowering time in response to changes in ambient temperature is FLOWERING LOCUS M (FLM). FLM transcripts can undergo extensive alternative splicing producing multiple variants, of which FLM-β and FLM-δ are the most representative. While FLM-β codes for the flowering repressor FLM protein, translation of FLM-δ has the opposite effect on flowering. Here we show that the cyclin-dependent kinase G2 (CDKG2), together with its cognate cyclin, CYCLYN L1 (CYCL1) affects the alternative splicing of FLM, balancing the levels of FLM-β and FLM-δ across the ambient temperature range. In the absence of the CDKG2/CYCL1 complex, FLM-β expression is reduced while FLM-δ is increased in a temperature dependent manner and these changes are associated with an early flowering phenotype in the cdkg2 mutant lines. In addition, we found that transcript variants retaining the full FLM intron 1 are sequestered in the cell nucleus. Strikingly, FLM intron 1 splicing is also regulated by CDKG2/CYCL1. Our results provide evidence that temperature and CDKs regulate the alternative splicing of FLM, contributing to flowering time definition. article_number: '1680' article_processing_charge: No article_type: original author: - first_name: Candida full_name: Nibau, Candida last_name: Nibau - first_name: Marçal full_name: Gallemi, Marçal id: 460C6802-F248-11E8-B48F-1D18A9856A87 last_name: Gallemi orcid: 0000-0003-4675-6893 - first_name: Despoina full_name: Dadarou, Despoina last_name: Dadarou - first_name: John H. full_name: Doonan, John H. last_name: Doonan - first_name: Nicola full_name: Cavallari, Nicola id: 457160E6-F248-11E8-B48F-1D18A9856A87 last_name: Cavallari citation: ama: Nibau C, Gallemi M, Dadarou D, Doonan JH, Cavallari N.

Local fluctuations in water and nutrient availability, sudden changes in temperature or other abiotic and biotic stresses can trigger changes in the growth of plant organs. Multiple mutually interconnected hormonal signaling cascades act as essential endogenous translators of these exogenous signals in the adaptive responses of plants. Although the molecular backbones of hormone transduction pathways have been identified, the mechanisms underlying their interactions are largely unknown. Here, using genome wide transcriptome profiling we identify an auxin and cytokinin cross-talk component; SYNERGISTIC ON AUXIN AND CYTOKININ 1 (SYAC1), whose expression in roots is strictly dependent on both of these hormonal pathways. We show that SYAC1 is a regulator of secretory pathway, whose enhanced activity interferes with deposition of cell wall components and can fine-tune organ growth and sensitivity to soil pathogens. acknowledged_ssus: - _id: Bio - _id: LifeSc acknowledgement: We thank Daria Siekhaus, Jiri Friml and Alexander Johnson for critical reading of the manuscript, Peter Pimpl, Christian Luschnig and Liwen Jiang for sharing published material, Lesia Rodriguez Solovey for technical assistance.

Crucial for proper bending is the local auxin maxima, which defines the concave (inner) side of the hook curvature. As no sign of asymmetric auxin distribution has been reported in embryonic hypocotyls prior to hook formation, the question of how auxin asymmetry is established in the early phases of seedling germination remains largely unanswered. Here, we analyzed the auxin distribution and expression of PIN auxin efflux carriers from early phases of germination, and show that bending of the root in response to gravity is the crucial initial cue that governs the hypocotyl bending required for apical hook formation. Importantly, polar auxin transport machinery is established gradually after germination starts as a result of tight root-hypocotyl interaction and a proper balance between abscisic acid and gibberellins. acknowledged_ssus: - _id: LifeSc - _id: Bio acknowledgement: "We thank Jiri Friml and Phillip Brewer for inspiring discussion and for help in preparing the manuscript.

Under such conditions plants respond to anticipate and/or adapt to the light shortage, a process known as the shade avoidance syndrome (SAS). Following genetic screening using a shade-responsive luciferase reporter line (PHYB:LUC), we identified DRACULA2 (DRA2), which encodes an Arabidopsis homolog of mammalian nucleoporin 98, a component of the nuclear pore complex (NPC). DRA2, together with other nucleoporins, participates positively in the control of the hypocotyl elongation response to plant proximity, a role that can be considered dependent on the nucleocytoplasmic transport of macromolecules (i.e. is transport dependent). In addition, our results reveal a specific role for DRA2 in controlling shade-induced gene expression. We suggest that this novel regulatory role of DRA2 is transport independent and that it might rely on its dynamic localization within and outside of the NPC. These results provide mechanistic insights in to how SAS responses are rapidly established by light conditions. They also indicate that nucleoporins have an active role in plant signaling. acknowledgement: M.G. received an FPI fellowship from the Spanish Ministerio de Economía y Competitividad (MINECO).

High spatial-resolution mapping of mechanical properties in live cells is, however, extremely challenging. Thus, our understanding of how signaling pathways process physiological signals to generate appropriate mechanical responses is limited. We introduce fluorescence emission-Brillouin scattering imaging (FBi), a method for the parallel and all-optical measurements of mechanical properties and fluorescence at the submicrometer scale in living organisms. Using FBi, we showed thatchanges in cellular hydrostatic pressure and cytoplasm viscoelasticity modulate the mechanical signatures of plant ECMs. We further established that the measured "stiffness" of plant ECMs is symmetrically patternedin hypocotyl cells undergoing directional growth. Finally, application of this method to Arabidopsis thaliana with photoreceptor mutants revealed that red and far-red light signals are essential modulators of ECM viscoelasticity. By mapping the viscoelastic signatures of a complex ECM, we provide proof of principlefor the organism-wide applicability of FBi for measuring the mechanical outputs of intracellular signaling pathways. As such, our work has implications for investigations of mechanosignaling pathways and developmental biology. article_number: rs5 author: - first_name: Kareem full_name: Elsayad, Kareem last_name: Elsayad - first_name: Stephanie full_name: Werner, Stephanie last_name: Werner - first_name: Marcal full_name: Gallemi Rovira, Marcal id: 460C6802-F248-11E8-B48F-1D18A9856A87 last_name: Gallemi Rovira - first_name: Jixiang full_name: Kong, Jixiang last_name: Kong - first_name: Edmundo full_name: Guajardo, Edmundo last_name: Guajardo - first_name: Lijuan full_name: Zhang, Lijuan last_name: Zhang - first_name: Yvon full_name: Jaillais, Yvon last_name: Jaillais - first_name: Thomas full_name: Greb, Thomas last_name: Greb - first_name: Youssef full_name: Belkhadir, Youssef last_name: Belkhadir citation: ama: Elsayad K, Werner S, Gallemi M, et al.
