Exogenous abscisic acid treatment regulates protein secretion in sorghum cell suspension cultures. (2023)
Journal Article

Drought stress adversely affects plant growth, often leading to total crop failure. Upon sensing soil water deficits, plants switch on biosynthesis of abscisic acid (ABA), a stress hormone for drought adaptation. Here, we used exogenous ABA applicati...
