Download or read book Cellular Signaling Mechanisms in Neurospora Crassa written by Arit Ghosh and published by . This book was released on 2016 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular signal transduction mechanisms are regulated at multiple different stages during an organism's life cycle as well as life span. Environmental stress and starvation responses are extremely well coordinated by cell surface receptors and internal scaffolding molecules that are routing the signal to the effector proteins such as transcription factors. It is through these transcription factors that the cell will then regulate gene expression. With the help of this study, my co-authors and me have tried to elucidate a signal transduction network, which explains various facets of cellular signaling in the model filamentous fungus - Neurospora crassa. The first chapter has elucidated the role of serine/threonine and tyrosine phosphatases in growth and development in Neurospora. In addition, the chapter also shows that deletion of certain phosphatases lead to sensitivities to chemicals inducing osmotic stress, oxidative stress, cytoskeletal defects or ROS accumulation. Nine phosphatase mutants are also listed to have elevated levels of the active phosphorylated form of p38 mitogen activated protein kinase (OS-2 in Neurospora) which is a critical regulator for counteraction to osmo-stress as well as an important regulator of female sexual development. Two other interesting genes - NCU04600 (pph-8) and NCU08380 (csp-6) are also described in this chapter for their unique phenotypes. The second chapter deals with the role of the important scaffolding protein and RACK1 homolog - CPC-2 in regulation of amino acid starvation mechanisms in Neurospora known as cross pathway control. CPC-2 is found to regulate the bZIP transcription factor - CPC-1 via modulation of post-translational modifications on CPC-1 during amino acid starvation. This transcription factor is in turn, integral towards de-repression of amino acid biosynthetic genes under amino acid starvation conditions. This chapter provides mechanistic details on how CPC-2 is able to regulate CPC-1 protein and thereby affect cross pathway control. In chapter III, the focus is shifted towards translational regulation via heterotrimeric G proteins and the guanine-exchange factor RIC-8 to build up a novel finding revealing that G proteins and RIC-8 are an integral part of the ribosome. Elevated phospho-eIF2[Alpha] levels in the G protein and ric-8 mutants suggest that global translation is greatly reduced in these strains. Poly-RNA-seq analyses of gna-1, gnb-1 and ric-8 mutants reveal certain ribosomal proteins as well as elongation factors and two serine/threonine kinases - stk-18 and stk-43 are greatly affected in polysomal co-migration by these gene deletions. In addition, deletion of ric-8 leads to loss of PKC protein from the polysomes, which suggests critical translational control of PKC via RIC-8. This thesis has thus aimed to expand on current knowledge on these abovementioned topics and laid the groundwork for future advances in understanding these cellular signaling mechanisms in Neurospora crassa.

Download or read book Signaling Mechanisms in Protozoa and Invertebrates written by G. Csaba and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative endocrinology helps to find the roots of homeostatic regulation in organisms. In this context, many years ago a series of experiments were done, which demonstrated the hormonal regula tion also on the invertebrate level. The mechanisms are partly similar, partly different, from those found in vertebrates. The new receptor era of mammalian endocrinology stimulated research on invertebrate hormone receptors, and sophisticated methods are applied also to determine hormones. The experiments demonstrated the existence and even similar function of these structures and signaling molecules. However, data on hormones and receptors at the lowest level of metazoan life and the highest level of protozoan life were not at our disposal. About two decades ago, first observations on the presence of hormone receptors reacting to vertebrate hormones in protozoa were made. Since the early 1980s we know that hormone-like molecules similar to those of higher vertebrates are present also in unicellular organisms. The presence of some second messengers in Tetrahymena was recognized. Since then, the research has been extended and many structures - previously believed to be solely vertebrate characteristics, such as opiate receptors, similar to mammalian ones - were found in unicellular organisms. These observations justified the assumption of a complete endocrine system at protozoan level, where - considering the unicellularit- this seemed to be not required. However, it became clear that the roots of endocrine communication date back at least 2 billion years.

Available in PDF, EPUB and Kindle. Book excerpt: These chapters provide up-to-date information on nematophagous fungi, particularly those of the Orbiliaceae in Ascomycota, whose asexual states produce nematode-trapping devices. The authors consider fungal-nematode interactions, fossil fungi, the biodiversity, ecology and geographical distribution of nematode-trapping fungi, and their potential use in biocontrol of nematodes, all in detail. Nematode-trapping fungi with adhesive or mechanical hyphal traps are the main focus of this book which begins with an overview of the data on nematode-trapping fungi, including their taxonomy, phylogeny and evolution. Subsequent chapters expand upon the methods and techniques used to study these fascinating fungi. Keys for genera of Arthrobotrys, Drechslerella and Dactylellina, which include all reported species of predatory orbiliaceous fungi are presented and numerous species from these genera are morphologically described and illustrated. The ecology of nematode-trapping fungi is expertly presented: their occurrence and habitats, their geographical and seasonal distribution and the effects of soil conditions and nematode density on their distribution all feature amongst the relevant themes. Further chapters examine the use of nematode-trapping fungi in biological control and the authors consider nematicidal activities in detail, exploring the many compounds from fungi that feature in nematicidal activities and of course useful paths for further study on this topic. This is a highly informative and carefully presented book, providing scientific insight for scholars with an interest in fungi and in biological control of nematodes.

Download or read book Phospholipid Metabolism in Cellular Signaling written by Jose M. Mato and published by CRC Press. This book was released on 1990-11-12 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phospholipids are no longer considered exclusively as the building blocks of biomembranes, but are now regarded to be exceptionally important to cellular signalling. Another conclusion resulting from studies over the past several years is that no single general scheme for the role of phospholipids during cell activation can be drawn as representative of all cells. Phospholipid Metabolism in Cellular Signaling presents a comprehensive view of the recent advances made in certain major research areas within the field of phospholipid metabolism in cellular signalling. Topics discussed within this volume include lipid composition of cellular membranes and their organization in biological systems, the dynamic aspects of phospholipid metabolism and its regulation by extracellular stimuli, and the role of newly discovered glycosyl-phosphatidylinositols in insulin action . The book also discusses two biologically active phospholipids: the sphingolipids, and ether-linked glycerophospholipids (the platelet activating factor). Phospholipid Metabolism in Cellular Signaling is an important research reference that should be considered required reading by all scientists and graduate students working on cell activation (e.g., growth factors, hormones, and oncogenes).

Download or read book Evolution by Gene Duplication written by Susumu Ohno and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is said that "necessity is the mother of invention". To be sure, wheels and pulleys were invented out of necessity by the tenacious minds of upright citi zens. Looking at the history of mankind, however, one has to add that "Ieisure is the mother of cultural improvement". Man's creative genius flourished only when his mind, freed from the worry of daily toils, was permitted to entertain apparently useless thoughts. In the same manner, one might say with regard to evolution that "natural selection mere(y tnodifted, while redundanry created". Natural selection has been extremely effective in policing alleHe mutations which arise in already existing gene loci. Because of natural selection, organisms have been able to adapt to changing environments, and by adaptive radiation many new species were created from a common ancestral form. Y et, being an effective policeman, natural selection is extremely conservative by nature. Had evolution been entirely dependent upon natural selection, from a bacterium only numerous forms of bacteria would have emerged. The creation of metazoans, vertebrates and finally mammals from unicellular organisms would have been quite impos sible, for such big leaps in evolution required the creation of new gene loci with previously nonexistent functions. Only the cistron which became redun dant was able to escape from the relentless pressure of natural selection, and by escaping, it accumulated formerly forbidden mutations to emerge as a new gene locus.
Download or read book Morphogenesis and Pathogenicity in Fungi written by José Pérez Martín and published by Springer. This book was released on 2014-02-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infectious fungal diseases continue to take their toll in terms of human suffering and enormous economic losses. Invasive infections by opportunistic fungal pathogens are a major cause of morbidity and mortality in immuno-compromised individuals. At the same time, plant pathogenic fungi have devastating effects on crop production and human health. New strategies for antifungal control are required to meet the challenges posed by these agents, and such approaches can only be developed through the identification of novel biochemical and molecular targets. However, in contrast to bacterial pathogens, fungi display a wealth of “lifestyles” and modes of infection. This diversity makes it extremely difficult to identify individual, evolutionarily conserved virulence determinants and represents a major stumbling block in the search for common antifungal targets. In order to activate the infection programme, all fungal pathogens must undergo appropriate developmental transitions that involve cellular differentiation and the introduction of a new morphogenetic programme. How growth, cell cycle progression and morphogenesis are co-ordinately regulated during development has been an active area of research in fungal model systems such as budding and fission yeast. By contrast, we have only limited knowledge of how these developmental processes shape fungal pathogenicity, or of the role of the cell cycle and morphogenesis regulators as true virulence factors. This book combines state-of-the-art expertise from diverse pathogen model systems to update our current understanding of the regulation of fungal morphogenesis as a key determinant of pathogenicity in fungi.
