Abscisic acid biosynthesis (WP626)

Arabidopsis thaliana

Abscisic acid (ABA), also known as ''abscisin II'' and ''dormin'', is a [[wikipedia:plant hormone|plant hormone]]. ABA functions in many plant developmental processes, including bud [[wikipedia:dormancy|dormancy]]. Source: [[wikipedia:Abscisic_acid|Wikipedia]]
