T04-111 Abiotic stress signaling and tolerance Jian-Kang Zhu(1) 1-University of California at Riverside Detecting and responding to environmental perturbations are important for all living organisms. Our lab is interested in the molecular mechanisms underlying plant responses to harsh environments such as soil salinity, drought and cold temperatures. In addition, we are interested in the mechanisms of transcriptional gene silencing and in the role of epigenetic gene regulation in stress adaptation. We use a combination of genetic, biochemical, genomic and proteomic approaches to analyze various levels of gene regulation (chromatin level/epigenetic, transcriptional, posttranscriptional, and protein activity) and to understand stress signaling and stress tolerance. Our long-term goals are to elucidate the signaling pathways used by plants in responding to environmental stresses and to identify key genes for modifying the responses of crops to environmental stresses which ultimately will lead to major contributions to agriculture and the environment. In this presentation, I will give an overview of recent progress in the area of abiotic stress responses, and describe some recent results from my lab on salt, drought and cold stress signal transduction in Arabidopsis. Potential involvement of microRNAs and other small regulatory RNAs in abiotic stress responses will be discussed. T04 Interaction with the Environment 1 (Abiotic) T04-112 Role of membrane fluidity in cold perception in Arabidopsis thaliana suspension cells. VAULTIER Marie-Noëlle(1), ZACHOWSKI Alain(1), RUELLAND Eric(1) 1-Physiologie Cellulaire et Moléculaire des Plantes, CNRS/Université Paris VI Perception and transduction mechanisms of cold signal begin to be elucidated in plant cells. Signalisation pathways implying phospholipases are part of the transduction (Ruelland et al., (2002) Plant Physiol.130: 999-1007). We wanted to characterize some of their properties in Arabidopsis thaliana suspension cells. The existence of a temperature threshold for phosphatidic acid production by phospholipase C and D in response to cold was demonstrated. Besides, we have shown that this temperature triggering of phospholipase C and D activation was shifted in systems where membrane fluidity was modified artificially (pretreating cells with fluidifying or rigidifying agents as benzyl alcohol or dimethylsulfoxyde, respectively), physiologically (acclimated cells) or genetically (mutants of desaturation pathways). Results have evidenced that membrane rigidification plays a central role in signal perception leading to phospholipase C and D activation when plant cells are exposed to cold 15 th <strong>International</strong> <strong>Conference</strong> on Arabidopsis Research 2004 · Berlin
