Download or read book Drought Stress Tolerance in Plants, Vol 1 written by Mohammad Anwar Hossain and published by Springer. This book was released on 2016-05-25 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abiotic stress adversely affects crop production worldwide, decreasing average yields for most of the crops to 50%. Among various abiotic stresses affecting agricultural production, drought stress is considered to be the main source of yield reduction around the globe. Due to an increasing world population, drought stress will lead to a serious food shortage by 2050. The situation may become worse due to predicated global climate change that may multiply the frequency and duration and severity of such abiotic stresses. Hence, there is an urgent need to improve our understanding on complex mechanisms of drought stress tolerance and to develop modern varieties that are more resilient to drought stress. Identification of the potential novel genes responsible for drought tolerance in crop plants will contribute to understanding the molecular mechanism of crop responses to drought stress. The discovery of novel genes, the analysis of their expression patterns in response to drought stress, and the determination of their potential functions in drought stress adaptation will provide the basis of effective engineering strategies to enhance crop drought stress tolerance. Although the in-depth water stress tolerance mechanisms is still unclear, it can be to some extent explained on the basis of ion homeostasis mediated by stress adaptation effectors, toxic radical scavenging, osmolyte biosynthesis, water transport, and long distance signaling response coordination. Importantly, complete elucidation of the physiological, biochemical, and molecular mechanisms for drought stress, perception, transduction, and tolerance is still a challenge to the plant biologists. The findings presented in volume 1 call attention to the physiological and biochemical modalities of drought stress that influence crop productivity, whereas volume 2 summarizes our current understanding on the molecular and genetic mechanisms of drought stress resistance in plants.

The reader is then introduced to the biochemistry, regulation, genetics, and evolution of nitrogen fixing in organisms; the receptors involved in bacterial chemotaxis and the nature of the sensing mechanism; the outer membrane of gram-negative bacteria; and bacterial functions involved in nutrient detection and acquisition. The roles played by organelles and surface layers in the adaptation of bacteria to their environment are also examined. The final chapter deals with the regulation of, and coordination between, the multitude of events involved in cell division in Escherichia coli. This monograph will be a useful resource for microbiologists, bacteriologists, biochemists, and biologists.
Book Synopsis Physiological Studies Related to Grain Yield in Winter Wheat by : Kevin James Donnelly
Download or read book Physiological Studies Related to Grain Yield in Winter Wheat written by Kevin James Donnelly and published by . This book was released on 1983 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: As indicator of the time of maximum grain dry weight accumulation (t[indice]max) and a better description of physiological processes associated with grain growth termination in winter wheat (Triticum aestivum L.) should assist cultivar improvement programs. Several cultivars were compared to determine t[indice]max and its relationship to visual changes and physiological activities of spikes. Two cubic polymonial functions fitted to kernel dry weigth accumulation data estimated t[indice]max more objectively than single cubic or quadratic models or a mean superation test. Loss of green color from all spike parts was the best indicator of t[indice]max. Kernels from different portions of spikes generally reached t[indice]max within one day. Green tissue at the botton of spikes assimilated carbon and supplied assimilate to upper portions after they had lost green color. Kernels depended on sources of assimilate other than spikes during final stages of growth, since spike net photosynthesis reached zero prior to t[indice]max. Spike gross photosynthesis continued until t[indice]max, partially offseting respiration. Spike respiration continued after t[indice]max, but kernel weights did not always decline. Geen tissue at the base of the flag leaf assimilated carbon wich was translocated to kernels after t[indice]max. Winter wheat produces meny shoots which fail to develop grain-bearing spikes. An understanding of the physiology of spikelles shoots and their influence on grain yields may suggest potential for cultivar improvement. Distribution of 14C-labelled assimilate from late-emerging tillers was monitored. The effects of tiller removal treatments and tiller development and survival patterns were also evaluated. When spikelless tillers were labelled with 14CO2 at jointing, over 50% of the label recovered at maturity was in parts other that the labelled tiller. Kernels contained less than 10%. The importance of kernels as a sink increased with later labelling and under stress. Some translocation occurred within 48 hours. Removal of small shoots at jointing decreased grain yields by decreasing kernel numbers. Shoot survival was positively correlated with spike and kernel numbers per unit area and grain yield. Lower-yielding cultivars with lower shoot survival invested more in larger shoots wich failed to produce spikes. Therefore, the positive contibution of spikeless shoots suggested by the 14CO2-labelling and tiller removal studies may not have compensated for the plants investiment in them.
