Biogenesis of Chloroplast Membranes
The glycolipid, phospholipid, pigment, and fatty acid content in whole y-1 cells during the greening process have been investigated. The time course of their changes indicates that phosphatidyl glycerol and glycolipids are the main lipids synthesized specifically during illumination of dark-grown cells, concomitant with an increase in the polyunsaturated C18:2 and C18:3 fatty acids. The pigment...
متن کاملChloroplast Ribosome Biogenesis in Chlamydomonas
Chloroplast protein synthesis in Chlamydomonas reinhardtii is dispensable when cells are provided acetate as a carbon source. Mutants defective in synthesis, assembly, or function of chloroplast ribosomes are therefore conditionally viable. Positive selection of nonphotosynthetic cells on arsenate has been combined with a simple screening procedure to isolate mutants with a broad spectrum of de...
متن کاملUpdate on Chloroplast Biogenesis Genetic Dissection of Chloroplast Biogenesis and Development: An Overview
The chloroplast is essential for photosynthesis and the production of hormones and metabolites. As a consequence, its biogenesis and development needs to be coordinated with seedling growth to ensure optimal rates of photosynthesis without oxidative damage upon seedling emergence. Studies into the processes of biogenesis and development of chloroplasts have shown how important chloroplast devel...
متن کاملThe ubiquitin-proteasome system regulates chloroplast biogenesis
In a recently published work, we identified the first chloroplast-localized E3 ligase, and showed that it degrades TOC translocon proteins by the ubiquitin-proteasome system (UPS). This regulation was found to be critical for plastid developmental transitions, such as the conversion of etioplasts to chloroplasts. Here we discuss the importance of SP1 for plants under different circumstances, an...
متن کاملA proteomic analysis of maize chloroplast biogenesis.
Proteomics studies to explore global patterns of protein expression in plant and green algal systems have proliferated within the past few years. Although most of these studies have involved mapping of the proteomes of various organs, tissues, cells, or organelles, comparative proteomics experiments have also led to the identification of proteins that change in abundance in various developmenta...
