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 کاملChloroplast Biogenesis 49 : Differences among Angiosperms in the Biosynthesis and Accumulation of Monovinyl and Divinyl Protochlorophyllide during Photoperiodic Greening.
Various angiosperms differed in their monovinyl and divinyl protochlorophyllide biosynthetic capabilities during the dark and light phases of photoperiodic growth. Some plant species such as Cucumis sativus L., Brassica juncea (L.) Coss., Brassica kaber (DC.) Wheeler, and Portulaca oleracea L. accumulated mainly divinyl protochlorophyllide at night. Monocotyledonous species such as Avena sativa...
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...
