Download or read book Chloroplast Biogenesis written by Udaya C. Biswal and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chloroplast is the organelle where the life-giving process photosynthesis takes place; it is the site where plants and algae produce food and oxygen that sustain our life. The story of how it originates from proplastids, and how it ultimately dies is beautifully portrayed by three authorities in the field: Basanti Biswal, Udaya Biswal and M. K. Raval. I consider it a great privilege and honor to have been asked to write this foreword. The book ' Chloroplast biogenesis: from proplastid to gerontoplast' goes much beyond photosynthesis. The character of the book is different from that of many currently available books because it provides an integrated approach to cover the entire life span of the organelle including its senescence and death. The books available are mostly confined to the topics relating to the 'build up' or development of chloroplast during greening. The story of organelle biogenesis without description of the events associated with its regulated dismantling during genetically programmed senescence is incomplete. A large volume of literature is available in this area of chloroplast senescence accumulated during the last 20 years. Although some of the findings in this field have been organized in the form of reviews, the data in the book are generalized and integrated with simple text and graphics. This book describes the structural features of prop las tid and its transformation to fully mature chloroplast, which is subsequently transformed into gerontoplast exhibiting senescence syndrome. The book consists of five major chapters.

This book was released on 2012-12-06 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: From July 28 to August 3, 1991, an International Meeting on the REGULATION OF CHLOROPLAST BIOGENESIS was held at the capsis Beach Hotel in Aghia Pelaghia, on the island of crete, Greece. The Meeting (Advanced Research Workshop-Lecture Course) was co-sponsored by NATO, FEBS and IUB, and was held under the auspices of the International society for Chloro plast Development, the Greek Ministry of Industry, Research and Technol ogy, and the National Center for Scientific Research "Demokritos". The Meeting focused on recent advances in the field of chloroplast biogenesis and the regulatory mechanisms underlined, and brought together over 120 experts and students of the field from 22 countries. The subject of chloroplast biogenesis has experienced great progress in recent years mainly thanks to the application of Molecular Biology techniques and methodology. New findings that emerge gradually unravel the regulatory mechanisms involved in the assembly, stabilization and growth of the photosynthetic units in thylakoids, the signal transduction chain leading from photoreception to gene expression, the transport of nuclear-coded proteins into stroma-soluble supramolecular enzyme complexes as well as thylakoid-bound supramolecular complexes, involved in light-energy transduction. It was the aim of this meeting to bring together experts and students coming from diverse disciplines (ranging from Botany and plant physiology to Molecular Biology, Biophysics and Biotechnology), to discuss the recent advances in the field so that thorough exchange of ideas and working hypotheses would be achieved.

Download or read book Plastid Development in Leaves during Growth and Senescence written by Basanti Biswal and published by Springer Science & Business Media. This book was released on 2013-07-08 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chloroplast development is a key feature of leaf developmental program. Recent advances in plant biology reveal that chloroplasts also determine the development, the structure and the physiology of the entire plant. The books, published thus far, have emphasized the biogenesis of the organelle, but not the events associated with the transformation of the mature chloroplast to the gerontoplast during senescence. This book, with 28 chapters, is unique because it describes how the chloroplast matures and how it is subsequently transformed to become the gerontoplast during senescence, a process required for nutrient recycling in plants. This book includes a state-of-the-art survey of the current knowledge on the regulation and the mechanisms of chloroplast development. Some of the chapters critically discuss the signaling process, the expression potential of plastid DNA, the interaction of cellular organelles, and the molecular mechanisms associated with the assembly and the disassembly of organellar complexes and finally the modulation of chloroplast development by environmental signals.

Download or read book Regulation of Chloroplast Biogenesis written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The immutans (im) variegation mutant of Arabidopsis is an ideal model to gain insight into factors that control chloroplast biogenesis. im defines the gene for PTOX, a plastoquinol terminal oxidase that participates in control of thylakoid redox. Here, we report that the im defect can be suppressed during the late stages of plant development by gigantea (gi2), which defines the gene for GIGANTEA (GI), a central component of the circadian clock that plays a poorly-understood role in diverse plant developmental processes. imgi2 mutants are late-flowering and display other well-known phenotypes associated with gi2, such as starch accumulation and resistance to oxidative stress. We show that the restoration of chloroplast biogenesis in imgi2 is caused by a developmental-specific de-repression of cytokinin signaling that involves crosstalk with signaling pathways mediated by gibberellin (GA) and SPINDLY (SPY), a GA response inhibitor. Suppression of the plastid defect in imgi2 is likely caused by a relaxation of excitation pressures in developing plastids by factors contributed by gi2, including enhanced rates of photosynthesis and increased resistance to oxidative stress. Interestingly, the suppression phenotype of imgi can be mimicked by crossing im with the starch accumulation mutant, sex1, perhaps because sex1 utilizes pathways similar to gi. We conclude that our studies provide a direct genetic linkage between GIGANTEA and chloroplast biogenesis, and we construct a model of interactions between signaling pathways mediated by gi, GA, SPY, cytokinins, and sex1 that are required for chloroplast biogenesis.

Download or read book Chloroplast Biogenesis Diversity and Regulation of the Protein Import Apparatus written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The biogenesis of chloroplasts is dependent on the coordinate expression of genes encoded in both nuclear and plastid genomes. The chloroplast protein import machinery plays key roles in organelle biogenesis by mediating the import and assembly of thousands of nuclear-encoded proteins into the organelle. It is now apparent that multiple levels of control exist to integrate the activities of the protein import apparatus into the network of chloroplast-nuclear communication that is essential to maintain organelle homeostasis. The import apparatus has diversified into small, functionally specialized gene families to coordinate the import of distinct classes of differentially expressed proteins. Protein targeting to chloroplasts also has evolved regulatory mechanisms that respond to cellular developmental and physiological changes, including redox sensing, phosphorylation, and dual targeting. Recent studies also have revealed new components that could represent additional levels of control on the import process.

Download or read book Advances in Plastid Biology and Its Applications written by Niaz Ahmad and published by Frontiers Media SA. This book was released on 2016-12-12 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the distinguishing features of plants is the presence of membrane-bound organelles called plastids. Starting from proplastids (undifferentiated plastids) they readily develop into specialised types, which are involved in a range of cellular functions such as photosynthesis, nitrogen assimilation, biosynthesis of sucrose, starch, chlorophyll, carotenoids, fatty acids, amino acids, and secondary metabolites as well as a number of metabolic reactions like sulphur metabolism, The central role of plastids in many aspects of plant cell biology means an in-depth understanding is key for a holistic view of plant physiology. Despite the vast amount of research, the molecular details of many aspects of plastid biology remains limited. Plastids possess their own high-copy number genome known as the plastome. Manipulation of the plastid genome has been developed as an alternative way to developing transgenic plants for various biotechnological applications. High-copy number of the plastome, site-specific integration of transgenes through homologous recombination, and potential to express proteins at high levels (>70% of total soluble proteins has been reported in some cases) are some of the technologies being developed. Additionally, plastids are inherited maternally, providing a natural gene containment system, and do not follow Mendelian laws of inheritance, allowing each individual member of the progeny of a transplastomic line to uniformly express transgene(s). Both algal and higher plant chloroplast transformation has been demonstrated, and with the ability to be propagated either in bioreactors or in the field, both systems are well suited for scale up of production. The manipulation of chloroplast genes is also essential for many approaches that attempt to increase biomass accumulation or re-routing metabolic pathways for biofortification, food and fuel production. This includes metabolic engineering for lipid production, adapting the light harvesting apparatus to improve solar conversion efficiencies and engineering means of suppressing photorespiration in crop species, which range from the introduction of artificial carbon concentrating mechanisms, or those pre-existing elsewhere in nature, to bypassing ribulose bisphosphate carboxylase/oxygenase entirely. The purpose of this eBook is to provide a compilation of the latest research on various aspects of plastid biology including basic biology, biopharming, metabolic engineering, bio-fortification, stress physiology, and biofuel production.
