This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rinie Hofstra has been a member of the Department of Plant Physiology, University of Groningen, the Netherlands, for 24 years. The nearer we came to 31 March 1985, her 65th birthday, the more we all realized how we would miss her - not only scientifically, but also socially. She left her mark on both research and teaching, always with an open mind and willing to change. After her PhD Thesis on 'Nitrogen Metabolism in Tomato Plants' she first continued working in that field, but soon started a joint project with the Department of Plant Ecology on hemiparasites. She then became involved in carbon metabolism, which resulted in her giving a Biotrop Course on C /C metabolism in 3 4 Indonesia. Her own research group, originally working on 'Nitrogen Metabolism', soon embraced 'Energy and Nitrogen Metabolism', as the research on respiration became more and more important. In running her group she showed all sides of her person. She used to stimulate and encourage everyone around her and to integrate the various lines of research. At the same time she always had an open mind for the opinion of all members of her group. And together they regularly criticized and evaluated the various projects and decided how to continue.

Download or read book Plant Rhizobia Symbiosis and Nitrogen Fixation in Legumes written by and published by Frontiers Media SA. This book was released on 2024-04-29 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reciprocal exchange of chemical signals between legume and rhizobium leads to the establishment of Root Nodule Symbiosis (RNS). The discoveries of the Nodulation Factor (NF) and nod genes, along with the discoveries of the relevant genetic plant factors, have expanded our understanding of how legume-rhizobial interactions constitute a successful mutualistic symbiosis. Symbiotic nodule formation can be divided into the following molecular events: (i) the reciprocal exchange of signals; (ii) epidermal recognition of symbiotic partner and infection thread formation; (iii) nodule organogenesis; (iv) the establishment of a microaerophilic environment to provide nitrogenase the ideal condition to work; and, (v) modulation of immunity to host rhizobium inside the nodule cells. The number of nodules in a plant is maintained via a process of systemic signaling, known as ‘autoregulation of nodulation’ (AON), that acts as a negative signal to control nodule number in low nitrogen conditions and inhibit nodule initiation in an optimally nitrogen-fed plant. Over 200 plant genes have been discovered up to now and these discoveries have given us a broad understanding of RNS.

Download or read book Plant Pathology written by George Agrios and published by Elsevier. This book was released on 2012-12-02 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Pathology, Second Edition incorporates developments in identifying pathogens and disease diagnosis. This book is organized into two major parts encompassing 16 chapters that discuss general aspects of plant diseases and specific plant diseases caused by various microorganisms. This edition includes chapters or sections on diseases caused by mycoplasma-like organisms, rickettsia-like bacteria, viroids, and protozoa. Information on the genetics of plant diseases, the development of resistant varieties, and their vulnerability to new pathogen races is added in this release. It also includes information on the development of epidemics. The presentation of these topics is followed by a discussion on systemic fungicides and biological control of diseases, as well as postharvest diseases of plant products. Furthermore, this edition also explains mycotoxins and mycotoxicoses, as well as techniques of isolation, culturing, indexing, and identification of pathogens. It also studies mycorrhiza and root-nodule bacteria. Considerable chapters describe diseases caused by fungi and those caused by bacteria, which have been organized in logical, cohesive groups according to their most important symptoms. Diagrams of disease cycles, groups of pathogens and symptoms, and techniques and concepts of plant pathology are incorporated in each chapter. Moreover, this edition provides numerous photographs (macroscopic, microscopic, electron micrographs, and scanning electron micrographs) that illustrate concepts, pathogens, and symptoms. Teachers and students who are interested in plant pathology and plant diseases and control will find this book very helpful.

Download or read book Techniques and New Developments in Photosynthesis Research written by J. Barber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: From July 31 to August 13 a NATO Advanced Study Institute on Photosynthesis was held at the Anargyrios and Korgialenios School on the Island of Spetsai. Greece. The Institute focused on techniques and recent advances in photosynthesis research and brought together teachers and students with a wide range of interest and experience. It was a very stimulating occasion which allowed cross-fertilization to occur between biophysicists. biochemists, molecular biologists and physiologists. Lectures and discussions ran~ed from the description of the molecular structure of the photosynthetIc bacterial reaction centre and of tobacco Rubisco through to the regulation of carbon metabolism and the application of genetic engeering. This book is comprised of the contents of the major lectures and a selection of relevant posters displayed at the Institute. Taken together the book is an excellent representation of the most up to date thoughts and activities in photosynthesis research across a wide, but interlocking. spectrum of topics. The papers presented here are a written record of the high quality of both the lecturers and students alike and emphasises the value of the NATO ASI series as a reference source. The successful organisation of the Institute and the production of this book would not have been possible without the support of our colleagues. We therefore wish to thank Pam Cook, Lyn Barber. Niki Gounaris, Alison Telfer. Sotiria Nikolaidon, David Chapman, Steven Mayes and Wei Qiu Wang for all their help during the course of the Institute.
