This book was released on 1975 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the phenomenon of photorespiration (a light stimulated respiration in photosynthetic organisms) has attracted considerable interest among higher plant physiologists. The biochemistry of this phenomenon is different from that of the normal dark respiration and the existence of photorespiration is an indication of important characteristics of the photosynthetic mechanism. Little is known of photorespiration among marine phytoplankton. This paper reports the results of studies with the marine diatom Phaeodactylum tricornutum. Two pieces of evidence suggest that photorespiration exists in this alga; the oxygen inhibition of photosynthesis, particularly at low carbon dioxide concentrations and the presence of a ribulose diphosphate dependent oxygenase activity in cell-free extracts. This paper will discuss the possible significance of these observations to the photosynthetic efficiency of marine phytoplankton.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive guide is designed for researchers, professionals, and students looking to deepen their knowledge of diatoms, including detailed information on diatom photosynthesis regulation at the molecular scale, as well as their significant ecological roles, all aimed at promoting sustainable advancements and the safeguarding of aquatic ecosystems. Diatoms exert an immense influence on the ecosystem of Earth due to their remarkable abundance and species diversity. Thriving in diverse habitats spanning the oceans, intertidal benthic zones, saline and freshwater environments, and even terrestrial niches like moist soil, forests, and caves, they play an integral role. Diatoms alone account for around 20% of the oxygen generated by photosynthesis, comparable to the combined productivity of tropical rainforests worldwide, while their primary production can reach 40–45% in marine ecosystems. Nevertheless, in contrast to the extensive research on macroscopic photosynthetic organisms, investigations in this domain remain comparatively limited, despite the role of diatoms in global biogeochemical processes. This book presents an exhaustive review of the subject matter, encompassing a wide spectrum of topics ranging from the intricate molecular mechanisms of diatom photosynthesis and light absorption to the dominant role of diatoms as primary producers within ecological frameworks. Beyond this, the book delves into the practical implications stemming from diatoms and their photosynthetic productivity. A strong emphasis is placed on the importance of fundamental research in deepening our understanding of the natural world around us. Diatoms Photosynthesis provides readers with a comprehensive guide to understanding the fundamentals of diatom photosynthesis and their ecological significance in aquatic ecosystems; a guide to the potential of diatom-derived products for sustainable technologies; a roadmap from diatom photosynthesis to implications in applied sciences; a bridge to span the gap between fundamental research on diatoms and their practical applications. Audience This book caters to academic professionals, students, and researchers in the fields of marine biology, ecology, microbiology, and biochemistry. It offers insights and benefits into diatom photosynthesis, diatom physiology, biodiversity, ecosystem health, and sustainable technological advancements.

This book was released on 2020-06-03 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae, including cyanobacteria, are in the spotlight today for a number of reasons; firstly it has become abundantly clear over recent years that algae have been neglected in terms of basic research and that knowledge gap is being rapidly closed with the establishment of some surprising discoveries, such as the presence of Near-Infra-Red-Absorbing cyanobacteria and a wealth of natural products; secondly molecular approaches have provided a wealth of approaches to genetically modify algae and produce value-added products; thirdly it has become clear just how important, marine phytoplankton is to global carbon capture and the production of food globally; and fourthly, it has also become clear that algae present unparalleled opportunities to generate biofuels in a sustainable and non-polluting way. This volume presents 15 chapters by world experts on their subjects, ranging from reviews of algal diversity and genetics to in-depth reviews of special algal groups such as diatoms (which account for over 30% of marine carbon capture). Other chapters chart the ways in which this carbon capture occurs or how there are a multiplicity of ways in which algae intercept sun light and deploy this energy for carbon capture. A fascinating aspect here is the way in which sun light is harvested. A special chapter is devoted to the very recent and exciting possibility that algae use coherent light energy transformation to enhance the efficiency of light capture, an aspect of quantum physics that has implications for future developments at several levels and a variety of industries. Just how and why algae use Chlorophyll a as the major light capture pigment is discussed in several chapters. However, attention is also given to those cyanobacteria, which have been found to use the special Near-Infra Red absorbing chlorophylls mentioned above. And attention is also given to those algae that employ phycobiliproteins to fill in the “green window”, i.e., the spectral region from 400 – 650 nm, which is not efficiently covered by chlorophyll and carotenoid pigments. Photoinhibition and photoprotection is the subject area of several chapters and one which it is essential to understand a we work towards greater efficiency of algal photosynthesis. A final chapter is devoted to understanding the molecular basis for coral bleaching, a much-neglected area that is essential in trying to come up with solutions to this very worrying phenomenon, caused by global warming and ocean acidification. This is a book for research scientists, environmentalists, planners in a range of areas including those of marine resources, nutrient control and pollution of water bodies and that growing body of concerned citizens interested in controlling carbon emissions and global warming. Special attention has been given to generating a set of articles that will be read by university students, informed laymen and all those whose wish to understand the rapid changes that have come about in our knowledge of algae over the past decade.

Download or read book Early Responses of the Marine Diatom Phaeodactylum Tricornutum to Herbivory-related Decadienal written by Shahima Islam and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide food security is based on crop production which largely depends on plants’ stress tolerance capacities at the onset of diverse biotic and abiotic stresses. Photosynthetic organisms have developed many sophisticated defense responses that balance maintenance of central metabolic processes such as photosynthesis with new metabolic demands for acclimation to the stress. However, in both higher plants and algae, how central metabolic pathway-related genes are regulated and the functional significance of the adjustments are poorly understood. Marine diatoms are known to cope with continuous challenges of stress in the ocean and can provide general insights on the roles of rapid photosynthetic and core carbon metabolism gene expression changes in acclimation. During zooplankton grazing, damaged diatom cells release polyunsaturated aldehyde (PUA) from membranes, which impair reproduction in grazers and at the same time affect neighboring undamaged diatoms. In response to PUA, undamaged diatoms cells exhibit remarkable alteration in the photosynthesis-related gene expression. In this study, early response dynamics in the marine diatom Phaeodactylum tricornutum were investigated in response to sublethal concentrations of a model PUA, 2-E, 4-E/Z-decadienal (DD). Genome-wide analysis showed mRNAs encoding photosynthetic Light Harvesting Complex (LHC) antenna proteins were differentially downregulated except for a few upregulated mRNAs at 3 and 6 h of DD treatments. Our findings revealed gene regulatory mechanisms of two differentially regulated LHC transcripts. In cells treated with DD, he downregulation of Lhcf2 mRNA was due to reduced transcription and increased mRNA turnover, and Lhcf15 upregulation depended on increased transcription and mRNA stability. Further, I compared changes in the transcriptome and proteome, especially for photosynthesis-and central carbon metabolism-related pathways to investigate early molecular responses during short-term sublethal DD treatment. The majority of the differentially expressed transcripts involved in photosynthetic light harvesting, chlorophyll biosynthesis were downregulated and central carbon metabolism exhibited a mixed expression. In contrast, few of the corresponding proteins exhibited differential expression. Thus, during the early exposure to DD, proteins involved in photosynthesis-and energyrelated pathway remained predominantly stable despite extensive differential expression of their encoding transcripts. I have postulated that transient suppression of transcripts is an early defense response to save energy and resources to support synthesizing important components needed for acclimation to DD induced stress. Hence, our study provides novel insight into the photosynthetic gene regulatory mechanism and metabolic network reprogramming during early stress response of herbivory-related DD stress condition

Book excerpt: Increasing atmospheric CO2 levels have led to disastrous consequences that have impacted many people's lives. In nature, photosynthesis is the primary sink of CO2 in the air and in the ocean. A better understanding of the light harvesting and utilization mechanisms can help us better design photosynthetic organisms or artificial photosynthetic systems to utilize and reduce CO2 levels in the natural environment. Thanks to advancements in computational biology and bioinformatics in the past decade, we are now capable of achieving this task from a new prospective, with data analysis accomplished more quantitatively and comprehensively than ever before. A marine diatom, Phaeodactylum tricornutum, was selected to be the model species in my study because of its wide range of light intensity tolerances and its capability of photoprotection to high light stress. The primary objective of this dissertation is to characterize the light utilization and photoprotection associated energy and metabolic mechanisms in this organism that allow it to have such extraordinary features. In the first chapter, the cross-compartment energy and metabolite rebalancing was investigated by flux simulation developed from physiological experimental data and genome scale metabolic modeling. In the second chapter, a novel instrument for simultaneous measurement of carbon uptake and oxygen evolution was developed to provide additional insight into the light utilization efficiencies during photoacclimation period. In the third chapter, a comprehensive study, using both classic physiology and novel machine learning approaches, was conducted to investigate the function of a high light stress related protein (LHCX1) in photoprotection during acclimation. Taken together, these chapters significantly improve our understanding of photoprotective and energy utilization mechanisms in P. tricornutum that enable their remarkable success in adaptations to varying light conditions.
