Accumulating evidence suggest that certain annexins can play a role in abiotic stress responses in plants. We found that for one member of the Arabidopsis thaliana annexin gene family, annexin 1 (AnnAt1), loss-of-function mutants are more sensitive to drought stress and gain-of-function mutants are more tolerant. We also found that AnnAt1 is able to regulate accumulation of H(2)O(2) in vivo in Arabidopsis cells based on the observation that the level of ROS accumulation following induction by… CONTINUE READING
