General Information

General Information Comment Organism
physiological function C3HC4-type RING E3 ubiquitin ligase AIRP2-overexpressing transgenic and loss-of-function mutant plants exhibit hypersensitive and hyposensitive phenotypes, respectively, to abscisic acid in terms of seed germination, root growth, and stomatal movement. Overexpressing transgenic plants are highly tolerant to severe drought stress, and loss-of-function mutant alleles are more susceptible to water stress than are wild-type plants. Higher levels of drought-induced hydrogen peroxide production are detected in overexpressing mutant as compared with loss-of-function mutant plants. Abscisic acid-inducible drought-related genes are up-regulated in overexpressing and down-regulated in loss-of-function progeny. The positive effects of AIRP2 on abscisic acid-induced stress genes are dependent on SNF1-related protein kinases Arabidopsis thaliana
