SUMMARY:Redox and ROS Signaling During Plant Responses to Abiotic Stress

DESCRIPTION:Plants grow and reproduce within a highly dynamic environment 
 that can see abrupt changes in conditions\, such as light intensity\, temp
 erature\, humidity\, and/or the presence of different pathogens and insect
 s. Recent studies revealed that plants can respond within minutes to some 
 of these conditions\, engaging many different metabolic and molecular netw
 orks\, as well as rapidly altering their stomatal aperture. \n\nSome of th
 ese rapid responses were further shown to propagate throughout the entire 
 plant via waves of reactive oxygen species (ROS)\, redox\, membrane potent
 ial\, Ca2+\, and hydraulic pressure\, mediated through the plant vascular 
 system. New findings reveal that several different plasmodesmata-associate
 d proteins\, calcium channels\, and respiratory burst oxidase homologs (RB
 OHs) play key roles in regulating and integrating these signals. In additi
 on\, new findings identified a key role for ROS and different plant hormon
 es in mediating the acclimation of plants to conditions of stress combinat
 ion. \n\nThe role of ROS in sensing\, transducing\, and activating plant r
 esponses to environmental stresses will be discussed along with different 
 models and hypotheses as to how ROS are involved in the rapid systemic sig
 naling process of plants and how they integrate different signal transduct
 ion processes during stress combination. \n\nContact reception@plantsci.ca

 of Cambridge and alumni to keep them as informal as possible.
