Post‐translational control of ABA signalling: the roles of protein phosphorylation and ubiquitination

Summary The plant phytohormone abscisic acid ( ABA ) plays significant roles in integrating environmental signals with embryogenesis, germination, seedling establishment, the floral transition and the adaptation of plants to stressful environments by modulating stomatal movement and stress‐responsive gene expression. ABA signalling consists of ABA perception, signal transduction and ABA ‐induced responses. ABA receptors such as members of the...
