This thesis is divided into 4 chapters summarizing this contribution on selected topics related to chlorophyll biosynthesis and biogenesis of the photosynthetic apparatus. The first chapter deals with the state of Pchlide in nonilluminated leaves. The comparison of the photoactive Pchlide absorbance spectra throughout the development in the dark, reveals that the proportion of P638-645 and P650-657 is not much modified during this period. The Gaussian deconvolutions of 77 K fluorescence spectra of nonphotoactive and photoactive Pchlide indicated the presence of three and 5 spectral forms, respectively. None of the nonphotoactive Pchlide forms is accumulated during the dark-growth. In constrast, photoactive Pchlide P650-657 is particularly accumulated. In the second chapter, we describe the photoreduction of Pchlide to Chlide. We conclude that the mechanism of photoreduction is independent on the leaf developmental stage. Using 77 K fluorescence spectroscopy, the Chlide spectral forms corresponding to the three photoactive Pchlides were identified. In leaves with proplastids, C670-675 is mainly formed whereas in leaves with etioplasts C684-696 is produced. During the 1st hour of greening, the newly formed Chlide molecules are not protected by carotenoids. The evidence for the involvement of a photocycle involving two spectral forms of Chlide in protection of newly formed Chlide is presented. In the third chapter, a method for the isolation of photoactive Pchlide yielding complexes characterized by spectral properties similar to those found in intact leaves is described. In the fourth chapter, it is explained that the different fates of the first products of the photoreduction, described in the 2nd chapter, influence the greening process. In fact, C684-696 is only produced in small amounts in plants with proplastids. Therefore the increase of the photosynthetic activity of these leaves is delayed. Nevertheless, during the first 8 h of greening, a weak photosynthetic activity is detected in these leaves. Fluorescence measurements reveal that a large part of the Chl remains nonintegrated to the photosystems. In young leaves, rapid Chl integration into the photosynthetic units occurs when both carotenoids and Chl are massively synthesized.

Pigment-Protein Complexes in Plastids: Synthesis and Assembly covers the different aspects of biosynthesis, assembly, and function of pigment-protein complexes. This book focuses on the molecular biology and physiological relevance of chlorophyll-protein complexes. The regulation and biosynthesis of chlorophyll proteins that involve a coordinated expression of nuclear and plastid genes and require communication among the cell organelles to respond properly to changing light and temperature conditions are also deliberated. This publication is intended for researchers in the fields of plant molecular biology, genetics, plant physiology and biochemistry, and cell biology, as well as students and teachers in agriculture, horticulture, biology, and biochemistry interested in pigment-protein complexes.

Quite naturally, photosynthesis has achieved massive amounts of attention in recent years. Aside from being the most spectacular physiological process in plant growth, it is actually the key to our dealing with the potentially cataclysmic accumulation of carbon dioxide in the earth’s atmosphere. Unfortunately, while information is plentiful, all this attention has resulted in a scattered database on photosynthesis, with no contemporary starting point...at least until now. With the second edition of the Handbook of Photosynthesis, Mohammad Pessarakli once again fills the need for an authoritative and balanced resource by assembling a team of experts from across the globe. Together, they have created a comprehensive reference that in a single volume includes important background information, as well as the most recent research findings on photosynthesis. Completely Revised with Several New Chapters The handbook, a completely updated reworking of the critically acclaimed first edition, details all of the photosynthetic factors and processes under both normal and stressful conditions, covering lower and higher plants as well as related biochemistry and plant molecular biology. Divided into fourteen sections for ease of reference, with nearly 8000 bibliographic citations, the handbook contains authoritative contributions from over 80 scientists. It includes approximately 500 drawings, photographs, tables, and equations— all designed to reinforce and clarify important text material.

The Porphyrin Handbook, Volume 12: The Iron and Cobalt Pigments: Biosynthesis, Structure, and Degradation provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book presents the biochemical and clinical aspects of genetically transmitted or drug-induced diseases associated with errors in heme metabolism. Organized into eight chapters, this volume begins with an overview of the comparison of regulatory principles in animal and plant tetrapyrrole biosynthesis. This text then examines the biology and medical implications of porphyrin systems. Other chapters consider the transformation of hemes into bile pigments, the organic synthesis of bilins, and the pathways of degradation of chlorophyll in senescent plants. This book discusses as well the biosynthesis of porphyrins, vitamin B12, and chlorophylls. The final chapter deals with genome sequencing projects that provide sources of genes encoding the enzymes needed for the synthesis of the intermediates. This book is a valuable resource for research scientists, engineers, and clinicians.

A NATO Advanced Study Institute on "New Developments and Methods in Membrane Research and Biological Energy Transduction" was held in order to consider some of the most recent developments in membrane research methodologies and results, with particular emphasis on studies of biological energy transduction. The partic ipants in the Institute dealt with three general areas of membrane study: membrane structure (with emphasis on lipid and protein components), membrane component assembly (with particular emphasis on mitochondria and chloroplasts), and the specialized functions of certain membrane systems. This last area included discussions of topics such as drug transformation, the role of membrane electron transport in the generation of oxygen radicals, the effect of oxygen radicals on cellular homeostasis and on the structure, organization and function of the acetylcholine receptor. Lectures and posters were concerned with two central questions: what is the function of membrane structure in energy transduction and how can energy trans duction be effectively measured and assessed? This text presents the content of the major lectures and important posters presented during the Institute's program. In issuing this book, the editor hopes to convey the proceedings of the Institute to a larger audi ence and to offer a comprehensive account of those developments in membrane research that were considered on the Island of Spetsai between August 16 and August 29, 1984.

Annual Plant Reviews, Volume 14 It is difficult to over-state the importance of plant pigments in biology. Chlorophylls are arguably the most important organic compounds on earth, as they are required for photosynthesis. Carotenoids are also necessary for the survival of both plants and mammals, through their roles in photosynthesis and nutrition, respectively. The other plant pigment groups, such as flavonoids and betalains, have important roles in both the biology of plants and the organisms with which plants interact. This book provides an overview of pigment chemistry and biology, together with an up-to-date account of the biosynthesis of pigments and the modification of their production using biotechnology. The chapters cover a wide scope of pigmentation research - from the importance of structural diversity in generating the range of colours seen in plants, through to improving human health properties of crops by increasing pigment levels in transgenic plants. The volume is directed at researchers and professionals in plant biochemistry, molecular biology and genetics.
