ABSCISIC ACID AS AN INTERNAL INTEGRATOR OF MULTIPLE PHYSIOLOGICAL PROCESSES MODULATES LEAF SENESCENCE ONSET IN ARABIDOPSIS THALIANA

Abscisic acid as an internal integrator of multiple physiological processes modulates leaf senescence onset in Arabidopsis thaliana

Many studies have shown that exogenous abscisic acid (ABA) promotes leaf abscission and senescence.However, owing to a lack of genetic evidence, ABA function in plant senescence has not been clearly defined.Here, two-leaf early-senescence mutants (eas) that were CEDAR screened by chlorophyll fluorescence imaging and named eas1-1 and eas1-2 showed h
