Role of abscisic acid in modulating drought acclimation, agronomic characteristics and β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP) accumulation in grass pea (Lathyrus sativus L.).

Exogenous ABA improved the drought adaptability of grass pea and promoted the synthesis of β-ODAP in seeds but not in leaves. Our findings provide novel insights into the agronomic role of ABA in relation to β-ODAP enrichment in grass pea subjected to drought stress. © 2021 Society of Chemical Industry.
