    environmental signals in plants Export Event Save ical Send to Google Calendar Send to Yahoo Calendar Save ical Preserve formatting in description only supported in some calendar applications Close Thursday 04 February 2016 11 00am 12 30pm ABSTRACT Plant life cycle is strongly influenced by seasonal cues such as temperature Climate change most importantly increasing global temperatures associated with it poses a severe threat to global agriculture Plants can sense and respond to modest changes in ambient temperature Major outputs of the thermosensory responses include modulation of plant phenology and plant pathogen interactions Elevated ambient temperature accelerates growth and developmental transitions while compromising immunity The molecular mechanisms by which plants sense and integrate temperature signals are not well understood We are investigating how temperature is perceived and integrated with other environmental signals Our studies are particularly addressing how temperature signals are integrated into development and defense responses in plants Location Jozef Schell seminar room Contact Dr Vinod Kumar Cell and Developmental Biology John Innes Centre Norwich UNITED KINGDOM Back PSB Missions The Department Infrastructure Core Facilities International Projects Publications News Seminars About PSB PSB Missions The Department Infrastructure Core Facilities International Projects Publications News Seminars Research Groups Alain Goossens Lab

  • “Organ formation at the shoot apical meristem: from morphodynamics to morphomechanics”
    in some calendar applications Close Thursday 18 February 2016 02 00pm 03 30pm ABSTRACT The shoot apical meristem SAM is a small population of stem cells that continuously generates organs and tissues Meristem function and maintenance involve a complex network of regulatory genes and signalling molecules A major downstream target of this network is the extracellular matrix or cell wall which is a local determinant for both growth rates and growth directions However the precise link between cell wall structure and molecular regulation is not well understood To address this issue we have developed a computational and experimental pipeline aimed at expressing gene function in terms of quantified geometrical changes in tissue shape In parallel we have started to provide a more mechanistic view of shape control We have provided evidence for a model where molecular networks impact on both cell wall anisotropy and synthesis thus causing the rapid outgrowth of organs at specific locations More specifically this involves two interdependent processes the activation of wall remodelling enzymes and changes in microtubule dynamics Location Jozef Schell seminar room Contact Dr Jan Traas Laboratory of Plant Reproduction and Development INRA CNRS ENS lyon UCBL Lyon Cedex FRANCE Back PSB Missions The

  • "Epigenetic control of plant cell reprogramming"
    a pioneering study in 1950s that demonstrated the regeneration of whole plant bodies from fully differentiated somatic cells in vitro1 Plant cells exert this potential only when they encounter severe environmental damages and intact plants hardly develop callus unorganised cell mass or somatic embryos under favourable conditions Plant cells may possess a mechanism to prevent unscheduled dedifferentiation but little is known on this control2 We have previously shown that a group of AP2 ERF transcription factors named WOUND INDUCED DEDIFFERENTIATION1 4 WIND1 4 promotes wound induced cell dedifferentiation in Arabidopsis3 All of the WIND genes are strongly activated by wounding and overexpression of each of WIND genes is sufficient to produce callus in wild type plants We have recently uncovered that some of the WIND genes need to be epigenetically silenced by POLYCOMB REPRESSIVE COMPLEX 2 PRC2 to maintain the differentiated status of plant cells4 5 In this talk I will discuss how mature plant cells repress dedifferentiation and how environmental stress may override the developmental regulatory networks to trigger cellular reprogramming Steward et al 1958 Am J Bot 45 705 708 Ikeuchi et al 2013 Plant Cell l 25 4159 3173 Iwase et al 2011 Curr Biol 21 508

  • “A PI4P-driven electrostatic field controls cell membrane identity and signaling in plants”
    April 2016 11 00am 12 30pm ABSTRACT Many signaling proteins permanently or transiently localize to specific organelles for function It is well established that certain lipids act as biochemical landmarks to specify compartment identity However they also influence membrane biophysical properties which emerge as important features in specifying cellular territories Such parameters include the membrane inner surface potential which varies according to the lipid composition of each organelle Here we found that the plant plasma membrane PM and the cell plate of dividing cells have a unique electrostatic signature controlled by phosphatidylinositol 4 phosphate PI4P Our results further reveal that contrarily to other eukaryotes PI4P massively accumulates at the PM establishing it as a critical hallmark of this membrane in plants Membrane surface charges control the PM localization and function of the polar auxin transport regulator PINOID as well as proteins from the BRI1 KINASE INHIBITOR1 BKI1 MEMBRANE ASSOCIATED KINASE REGULATORs MAKRs family which are involved in brassinosteroid and receptor like kinase signaling We anticipate that this PI4P driven physical membrane property will control the localization and function of many proteins involved in development reproduction immunity and nutrition Location Jozef Schell seminar room Contact Dr Yvon Jaillais ENS Lyon RDP

  • "Big Data in the browser: Visual Analytics of large scale genome variation data"
    this talk we present a general introduction to the topic of Big Data We focus on web based Visual Analytics as an essential tool for the exploration of large scale genome variation data With this example we illustrate how modern innovations in web cloud technology have the potential to revolutionise the way big and complex data sets are shared explored and analysed in particular for large scientific collaboration projects involving
