摘　　要：Plant survival depends on seed germination,progression through post-germinative developmental checkpoints,and adaptation to abiotic stresses.All these processes underlie a tightly controlled regulation by the stress hormone abscisic acid(ABA)at different levels,even though the main research focuses on changes in transcript and protein abundance.Nevertheless,protein fate undergoes complex readjustments that allow signal transduction to be integrated into physiological responses.Among them,protein redox status,stability,capacity of oligomerization,formation of complexes,and subcellular compartmentalization become key points for plant reprogramming against stresses to acquire an optimal development.In this Spotlight,we highlight and discuss the latest advances in dissecting the mechanisms driving protein dynamics of nucleocytoplasmic trafficking in the cell and its relevance for regulating the stability of ABI5 and the ABI5-dependent AB A signaling pathway(Figure 1).
