Abstract excerpt

To gain more insight into ABA signaling mechanisms, we conducted genetic screens searching for mutants with altered ABA response in germination and post-germination growth. We isolated seven putative ABA-hypersensitive Arabidopsis mutants and named them ABA-hypersensitive germination (ahg). These mutants exhibited diminished germination or growth ability on medium supplemented with ABA. We further studied four of...
