WebMay 1, 2015 · Degradation of chloroplasts is a hallmark of both natural and stress-induced plant senescence. Autophagy and senescence-associated vacuoles are two established cellular pathways for chloroplast degradation. Recently, a third independent pathway for chloroplast degradation was reported. ... the Chloroplast Vesiculation (CV) protein … WebFeb 12, 2024 · A pathway for stress-induced chloroplast degradation that involves the CHLOROPLAST VESICULATION (CV) gene was characterized in rice (Oryza sativa) plants. OsCV expression was up-regulated with the age of the plants and when plants were exposed to water-deficit conditions.

WebJun 13, 2024 · Furthermore, integration analysis of the metabolome, transcriptome and proteome data indicated that ATG4 significantly affected the lipid metabolism, chlorophyll binding proteins and chloroplast biosynthesis. These data collectively lead us to propose a more sophisticated model to explain the cellular co-ordination of the process of autophagy. WebJun 17, 2024 · And the degradation of chloroplast proteins has been reported for three different pathways, autophagy, Senescence Associated Vacuoles (SAV) and Chloroplast Vesiculation (CV) ( Ishida et al., 2008; Xie et al., 2015 ). When the senescence process starts, plastids undergo serial changes in their ultrastructures.

WebAfter proteins are transported to the chloroplast, chloroplast vesiculation (CV) destabilizes the chloroplast and induces the formation of CCVs during senescence or under abiotic stress conditions, further delivering chloroplast proteins to the vacuole for proteolysis ( Wang and Blumwald, 2014 ). WebWe hypothesized that delaying chloroplast degradation by altering the activity of the tomato chloroplast vesiculation (CV) under stress would lead to more efficient use of carbon and nitrogen and to higher yields. Tomato CV is upregulated under stress conditions.
