Project description:The coordination of chloroplast and nuclear genome status are critical for plant cell function, but the mechanism remain largely unclear. In this study, we report that Arabidopsis thaliana CHLOROPLAST AND NUCLEUS DUAL-LOCALIZED PROTEIN 1 (CND1) maintains genome stability in both the chloroplast and the nucleus.
Project description:To explore the role and target of chloroplast proteases under heat stress, thylakoid membranes were isolated from wild-type and mutant chloroplast thylakoid membrane-localized proteases after heat stress and subjected to comparative quantification by LC-MS/MS analysis using the spectral counting method.

Project description:Chloroplast, the energy organelle unique to plants and green algae, performs a wide range of functions including photosynthesis and biosynthesis of metabolites. However, as the most important tuber crop worldwide, the potato (Solanum tuberosum) chloroplast proteome has not been explored. Here, we use Percoll density gradient centrifugation to isolate intact chloroplasts from leaves of potato cultivar E3 and establish a reference proteome map of potato chloroplast by bottom-up proteomics. A total of 1834 non-redundant proteins, including 51 proteins encoded by the chloroplast genome, were identified in the chloroplast proteome. Extensive sequence-based localization prediction revealed over 62% of proteins to be chloroplast resident by at least one algorithm. A total of 16 proteins were selected for evaluating the prediction result by transient fluorescence assay and confirmed that 14 of them were distributed on distinct internal compartments of the chloroplast. In addition, 136 phosphorylation sites were identified in 61 proteins encoded by chloroplast proteome. Furthermore, by a comparative analysis between chloroplast and previously reported amyloplast proteomes, we reconstruct the starch metabolic pathways in the two different types of plastids. Altogether, our results establish a comprehensive proteome map with post-translationally modified sites of potato chloroplast, which would provide the theoretical principle for the research of photosynthesis pathway and starch metabolism.
