Arabidopsis thaliana | Rha2b expression is induced by abscisic acid and drought stress | up |
General Information | Comment | Organism |
---|---|---|
physiological function | RING finger E3 ligase RHA2b expression is induced by abscisic acid and overexpression of RHA2b leads to abscisic acid-associated phenotypes such as abscisic acid hypersensitivity in seed germination and seedling growth, enhanced stomatal closure, reduced water loss, and, therefore, increased drought tolerance. T-DNA insertion mutant Rha2b-1 shows abscisic acid-insensitive phenotypes and reduced drought tolerance. A Rha2a Rha2b-1 double mutant generally enhances abscisic acid insensitivity of mutant Rha2b-1 in seed germination, seedling growth, and stomatal closure, suggesting that Rha2b and Rha2a act redundantly in regulating abscisic acid responses | Arabidopsis thaliana |
