Book Description
Molecular oxygen deficiency leads to altered cellular metabolism and can dramatically reduce crop productivity. Nearly all crops are negatively affected by a lack of oxygen (hypoxia) due to adverse environmental conditions such as excessive rain and soil waterlogging. Extensive efforts to fully understand how plants sense oxygen deficiency and their ability to respond using different strategies are crucial to increase hypoxia tolerance. Progress in our understanding has been significant in recent years. This topic certainly deserves more attention from the academic community; therefore, we have compiled a series of articles reflecting the advancements made thus far.

Book Description
Plants, like other living organisms, require oxygen and water supplies for sustaining their normal growth and development. The water requirement is generally met through a coordinated system of root-to-shoot communication. However, excessive soil moisture in the rhizosphere can impact normal functioning of plants by restricting oxygen supplies to the roots. To survive under hypoxic conditions, plants show cellular, molecular, and functional level adaptations. One temporary response could be switching to anaerobic respiration, and maintain energy production to some extent, via glycolysis and ethanol fermentation. However, root respiration, water, and nutrient uptake, and hormonal synthesis are severely impacted under sustained periods of oxygen deficiency. These belowground changes, in turn, affect shoot performance and yield formation by interfering with the key physiological processes.

Book Description
In the last half century, because of the raising world population and because of the many environmental issues posed by the industrialization, the amount of arable land per person has declined from 0.32 ha in 1961–1963 to 0.21 ha in 1997–1999 and is expected to drop further to 0.16 ha by 2030 and therefore is a severe menace to food security (FAO 2006). At the same time, about 12 million ha of irrigated land in the developing world has lost its productivity due to waterlogging and salinity. Waterlogging is a major problem for plant cultivation in many regions of the world. The reasons are in part due to climatic change that leads to the increased number of precipitations of great intensity, in part to land degradation. Considering India alone, the total area suffering from waterlogging is estimated to be about 3.3 million ha (Bhattacharya 1992), the major causes of waterlogging include super- ous irrigation supplies, seepage losses from canal, impeded sub-surface drainage, and lack of proper land development. In addition, many irrigated areas are s- jected to yield decline because of waterlogging due to inadequate drainage systems. Worldwide, it has been estimated that at least one-tenth of the irrigated cropland suffers from waterlogging.

Book Description
Originally published in 1998, Southern Forested Wetlands is an up to date, one source compendium of current knowledge on the wetland ecology of America’s southern forests. This book presents both the ecological and management aspects of these important ecosystems. The book was compiled by members of the Consortium for Research on southern forested wetlands, and was a collaboration of those working to conserve, study, and manage these economically and environmentally influential areas. The book covers geographic ranges from West Virginia to Florida, to Texas and inland north to Arkansas and Tennessee. It also addresses specific wetland types, including deep-water swamps, major and minor alluvial flood plains, pocosins and Carolina bays, mountain fens, pond cypress swamps, flatwoods wetlands, and mangroves.

Book Description
This comprehensive edited volume collects the most recent information with up-to-date citations, on the decrease in plant productivity under climatic changes and its link with global food security. The book emphasis on the crop management practices and recent advancement in the techniques for mitigating the negative effects of climate induced biotic and abiotic stress. It brings together 19 chapters developed by eminent researchers in the area of plant and environmental sciences. Global climate change is increasingly becoming a concern for future of agriculture. High levels of inorganic and organic pollutants and climatic stress adversely affects the sensitive and complex equation of natural resources and ecosystem services. To meet the increased food demand, plant productivity needs to be enhanced, therefore this book fills in the gap and brings together information on the physiological and molecular approaches for improving crop productivity. The book is resourceful reading material for researchers, faculty members, graduate and post graduate students of plant science, agriculture, agronomy, soil science, botany, Molecular biology and environmental science.

Book Description
Presents a multidisciplinary analysis of the integration among reactive oxygen species (ROS), reactive nitrogen species (RNS), and reactive sulfur species (RSS). Since plants are the main source of our food, the improvement of their productivity is the most important task for plant biologists. In this book, leading experts accumulate the recent development in the research on oxidative stress and approaches to enhance antioxidant defense system in crop plants. They discuss both the plant responses to oxidative stress and mechanisms of abiotic stress tolerance, and cover all of the recent approaches towards understanding oxidative stress in plants, providing comprehensive information about the topics. It also discusses how reactive nitrogen species and reactive sulfur species regulate plant physiology and plant tolerance to environmental stresses. Reactive Oxygen, Nitrogen and Sulfur Species in Plants: Production, Metabolism, Signaling and Defense Mechanisms covers everything readers need to know in four comprehensive sections. It starts by looking at reactive oxygen species metabolism and antioxidant defense. Next, it covers reactive nitrogen species metabolism and signaling before going on to reactive sulfur species metabolism and signaling. The book finishes with a section that looks at crosstalk among reactive oxygen, nitrogen, and sulfur species based on current research done by experts. Presents the newest method for understanding oxidative stress in plants. Covers both the plant responses to oxidative stress and mechanisms of abiotic stress tolerance Details the integration among reactive oxygen species (ROS), reactive nitrogen species (RNS) and reactive sulfur species (RSS) Written by 140 experts in the field of plant stress physiology, crop improvement, and genetic engineering Providing a comprehensive collection of up-to-date knowledge spanning from biosynthesis and metabolism to signaling pathways implicated in the involvement of RONSS to plant defense mechanisms, Reactive Oxygen, Nitrogen and Sulfur Species in Plants: Production, Metabolism, Signaling and Defense Mechanisms is an excellent book for plant breeders, molecular biologists, and plant physiologists, as well as a guide for students in the field of Plant Science.
