Changes in membrane polypeptide composition during greening of etiolated maize were investigated to confirm the existence of the developmental polypeptides of 12 - 15 kDa described recently in virescent soybean mutant [M. Droppa, M. L. Ghirardi, G. Horváth, and A. Melis, Biochim. Biophys. Acta 932, 138 - 145 (1988)]. These low molecular weight polypeptides were the most abundant proteins at the early stage of greening, but were largely absent from fully developed thylakoids. During greening the relative concentration of the 12-15 kDa polypeptides were inversely proportional to that of LHC II, suggesting a role of these polypeptides in the assembly of the LHC II and/or chloroplast development.

Abstract The high accumulation of phloridzin makes apple (Malus domestica) unique in the plant kingdom, which suggests a vital role of its biosynthesis in the physiological processes of apple. In our previous study, silencing MdUGT88F1 (a key UDP-glucose: phloretin 2'-O-glucosyltransferase gene) revealed the importance of phloridzin biosynthesis in apple development and Valsa canker resistance. Here, results from MdUGT88F1-silencing lines showed that phloridzin biosynthesis was indispensable for normal chloroplast development and photosynthetic carbon fixation by maintaining MdGLK1/2 expression. Interestingly, the increased phloridzin biosynthesis didn’t affect plant (or chloroplast) development but reduced nitrogen accumulation, leading to chlorophyll deficiency, light sensitivity, and sugar accumulation in MdUGT88F1-overexpressing apple lines during their growth and development. Further analysis revealed that MdUGT88F1-mediated phloridzin biosynthesis negatively regulated cytosolic glutamine synthetase1-asparagine synthetase-asparaginase (GS1-AS-ASPG) pathway of ammonium assimilation and limited chlorophyll synthesis in the shoots of apple. The interference of phloridzin biosynthesis in the GS1-AS-ASPG pathway was also assumed to be associated with its limitation of the carbon skeletons of ammonium assimilation through metabolic competition with the tricarboxylic acid cycle. Taken together, our findings shed light on the role of MdUGT88F1-mediated phloridzin biosynthesis in the coordination between carbon and nitrogen accumulation in apple trees.

Plant cells coordinately regulate the expression of nuclear and plastid genes that encode components of the photosynthetic apparatus. Nuclear genes that regulate chloroplast development and chloroplast gene expression provide part of this coordinate control. However, there is compelling evidence that information also flows in the opposite direction, from chloroplasts to the nucleus. This hypothesised, second pathway functions to coordinate the expression of nuclear genes encoding components of the photosynthetic apparatus with the functional state of the chloroplast. Here we review the evidence for the signal transduction pathway from the chloroplasts to the nucleus and suggest possible signal molecules.

Abstract Appearance of oxygenic photosynthesis in Cyanobacteria is a major event in the evolution of Life. It had an irreversible impact on our planet, promoting the Great Oxygenation Event (GOE), ~2.4 b.y.a. Ancient Cyanobacteria predating the GOE were Gloeobacter-type cells, having no thylakoids. They hosted photosystems in their cytoplasmic membrane. The driver of the GOE was proposed to be the transition from unicellular to filamentous Cyanobacteria. However, the appearance of thylakoids expanded the photosynthetic surface by multiple logs: this multiplier effect would be more coherent with an impact on the atmosphere. Primitive thylakoids self-organize as concentric parietal uninterrupted multilayers. The quest for their origin resists vesicular-based scenarios. This review reports studies supporting that Hexagonal II-forming gluco- and galactolipids at the periphery of the cytosolic membrane could be turned within nanoseconds and without any external source of energy into membrane multilayers. Comparison of lipid biosynthetic pathways further shows that ancient Cyanobacteria contained only one anionic Lamellar-forming lipid, phosphatidylglycerol. Acquisition of sulfoquinovosyldiacylglycerol biosynthesis correlates with thylakoid emergence, possibly enabling a sufficient provision of anionic lipids to trigger an Hexagonal II-to-Lamellar phase transition. With this non-vesicular lipid-phase transition, a framework is also available to reexamine the role of companion proteins in thylakoid biogenesis processes.
