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 biogenesis 51 : modulation of monovinyl and divinyl protochlorophyllide biosynthesis by light and darkness in vitro.
It is shown that the monovinyl and divinyl protochlorophyllide biosynthetic patterns of etiolated maize (Zea mays L.), and cucumber (Cucumis sativus L.) seedlings and of their isolated etiochloroplasts can be modulated by light and darkness as was shown for green photoperiodically grown plants (E. E. Carey, C. A. Rebeiz 1985 Plant Physiol. 79: 1-6). In etiolated corn and cucumber seedlings and ...
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...
