This book was released on 2014-04-30 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is important to find methods, which may alleviate the adverse effect of stress on the growth of plants. Salinity is an important stress world wide, unfavorably affecting plant growth and crop production, Here we have presented a new method, which can efficiently alleviate salinity stress on the growth and nitrogen fixing ability of soybean and the associative N fixing bacteria, Bradyrhizobium japonicum. During the process of symbiotic N fixation between soybean and B. japonicum, the initial stages of the process, most importantly the exchange of signal molecules between the two, symbionts, are unfavorably affected by the stress. Accordingly, we hypothesized, tested and proved that if the bacteria is preincubated with the specific signal molecule, genistein, they are able to alleviate salinity stress on the growth and N fixing ability of soybean and B. japonicum. The book can be used by a wide range of audience including students, researches, academicians and scientists at the related disciplines, including plant biology, plant physiology, microbiology, biotechnology, molecular biology, environment, etc. Hoping that such a contribution can be used efficiently and widely.

Download or read book Physiological and Biochemical Changes in the Soybean Glycine Max Cultivars Essex and Forrest in Response to Water deficit Stress written by Bhunesh Kothanur and published by . This book was released on 2016 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drought and water-deficit adversely affect plant productivity. Limited water is a multidimensional stress that induces a number of molecular, biochemical and physiological changes in affected plants. These changes include altered photosynthetic capacity, altered gas exchange and the accumulation of secondary compounds. Glycine max (L.) Merrill (soybean) is an important crop and drought is a major limitation to soybean yield world--wide. The objective of this study is to monitor the physiological and biochemical responses to water-deficit stress in seedlings of two G. max cultivars (i.e. Forrest and Essex). The responses measured are: 1) relative water content (RWC), 2) net photosynthesis, 3) stomatal conductance, 3) evaporation rate, 4) water use efficiency (WUE), 5) radiation use efficiency (RUE) and 6) trigonelline accumulation. Trigonelline is a secondary compound known to accumulate in soybean in response to salinity- and water-deficit-stress. 14 day-old seedlings of Forrest (cv.) and Essex (cv.) were grown on open benches in the SIUC greenhouse and water was withheld for six days (i.e.15-to-20 DAP). During the treatment, RWC declined in both cultivars—from 89 to 41% in Essex and 83 to 60% in Forrest. Concomitantly, net photosynthesis, stomatal conductance, evaporation rate, WUE and RUE also declined in both cultivars. As RWC declined, the amount of trigonelline increased in both cultivars—from 2.3 to 5.34 OD gFW-1 in Essex and 2.3 to 6.63 OD gFW -1 in Forrest. The data supports the idea that trigonelline may function as a compatible solute and that confirms the hypothesis that trigonelline is a biomarker for plant water status.

Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.

Download or read book Legume Nitrogen Fixation in a Changing Environment written by Saad Sulieman and published by Springer. This book was released on 2015-04-24 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population will grow more rapidly during the few coming years. This must be accompanied by a parallel increase in the agricultural production to secure adequate food. Sustainability considerations mandate that alternatives to chemical nitrogen fertilizers must be urgently sought. Biological nitrogen (N2) fixation, a microbiological process which converts atmospheric N2 into a plant-usable form, offers this alternative. Among these renewable sources, N2-fixing legumes offer an economically attractive and ecologically sound means of reducing external inputs and improving internal resources. Environmental factors such as drought, elevated temperature, salinity, soil acidity and rising CO2 are known to dramatically affect the symbiotic process and thus play a part in determining the actual amount of nitrogen fixed by a given legume in the field. Understanding how nodule N2 fixation responds to the environment is crucial for improving legume production and maintaining sustainability in the context of global change. In this thoughtful and provocative new Brief, we provide critical information on how current and projected future changes in the environment will affect legume growth and their symbiotic N2 fixing capabilities. Each section reviews the main drivers of environmental change on the legume performance that include drought, elevated temperature, salinity and rising CO2, and soil acidity. Importantly we discuss the molecular approaches to the analysis of the stress response in legumes and the possible biotechnological strategies to overcome their detrimental effects.

Book excerpt: Advances in molecular biology and genome research in the form of molecular breeding and genetic engineering put forward innovative prospects for improving productivity of many pulses crops. Pathways have been discovered, which include regulatory elements that modulate stress responses (e.g., transcription factors and protein kinases) and functional genes, which guard the cells (e.g., enzymes for generating protective metabolites and proteins). In addition, numerous quantitative trait loci (QTLs) associated with elevated stress tolerance have been cloned, resulting in the detection of critical genes for stress tolerance. Together these networks can be used to enhance stress tolerance in pulses. This book summarizes recent advances in pulse research for increasing productivity, improving biotic and abiotic stress tolerance, and enhancing nutritional quality.
