AbstractClathrin-mediated vesicular formation and trafficking are highly conserved in eukaryotic cells and are responsible for molecular cargo transport and signal transduction among organelles. It remains largely unknown whether clathrin-coated vesicles can be generated from chloroplasts. CHLOROPLAST VESICULATION (CV)-containing vesicles (CVVs) generate from chloroplasts and mediate chloroplast degradation under abiotic stress. In this study, we showed that CV interacted with the clathrin heavy chain (CHC) and induced vesicle budding from the chloroplast inner envelope membrane. Defects on CHC2 and the dynamin-encoding DRP1A gene affected CVV budding and releasing from chloroplast. CHC2 is also required for CV-induced chloroplast degradation and hypersensitivity to water stress. Moreover, GLYCERALDEHYDE-3-PHOSPHATE DEHYDROGENASE (GAPC) interacts with CV and impairs the CV-CHC2 interaction. GAPC1 overexpression inhibited CV-mediated chloroplast degradation and hypersensitivity to water stress. CV silencing alleviated the hypersensitivity of gapc1gapc2 plant to water stress. Together, our work revealed a pathway of clathrin-assisted CVV budding from the chloroplast inner envelope membrane, which mediated the stress-induced chloroplast degradation and stress response.

: Plants, as sessile organisms, are susceptible to a myriad of stress factors, especially abiotic stresses. Over the course of evolution, they have developed multiple mechanisms to sense and transduce environmental stimuli for appropriate responses. Among those, phosphorylation and dephosphorylation, regulated by protein kinases and protein phosphatases, respectively, are considered as crucial signal transduction mechanisms. Regarding the latter group, protein phosphatases type 2C (PP2Cs) represent the largest division of PPs. In addition, discovery of regulatory functions of PP2Cs in abscisic acid (ABA)-signaling pathway, the major signal transduction pathway in abiotic stress responses, indicates significant importance of PP2C members in plant adaptation to adverse environmental factors. In this review, current understanding of the roles of PP2Cs in different phytohormone-dependent pathways related to abiotic stress is summarized, highlighting the crosstalk between the ABA-signaling pathway with other hormonal pathways via certain ABA-related PP2Cs. We also updated progress of in planta characterization studies of PP2Cs under abiotic stress conditions, providing knowledge of PP2C manipulation in developing abiotic stress-tolerant crops.
