---|---|---|
physiological function | the magnesium-protoporphyrin IX chelatase H subunit (CHLH/ABAR) functions as a receptor for abscisic acid in Arabidopsis thaliana. ABAR is a key component connecting the circadian clock with abscisic acid-mediated plant responses to drought. ABAR antagonizes negative abscisic acid signaling regulators WRKYs to derepress abscisic acid-responsive genes | Arabidopsis thaliana |
