Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on early germination, one of maize germplasm most important strategies for adapting to drought-induced stress. Some genotypes have the ability to adapt by either reducing water losses or by increasing water uptake. Drought tolerance is also an adaptive strategy that enables crop plants to maintain their normal physiological processes and deliver higher economical yield despite drought stress. Several processes are involved in conferring drought tolerance in maize: the accumulation of osmolytes or antioxidants, plant growth regulators, stress proteins and water channel proteins, transcription factors and signal transduction pathways. Drought is one of the most detrimental forms of abiotic stress around the world and seriously limits the productivity of agricultural crops. Maize, one of the leading cereal crops in the world, is sensitive to drought stress. Maize harvests are affected by drought stress at different growth stages in different regions. Numerous events in the life of maize crops can be affected by drought stress: germination potential, seedling growth, seedling stand establishment, overall growth and development, pollen and silk development, anthesis silking interval, pollination, and embryo, endosperm and kernel development. Though every maize genotype has the ability to avoid or withstand drought stress, there is a concrete need to improve the level of adaptability to drought stress to address the global issue of food security. The most common biological strategies for improving drought stress resistance include screening available maize germplasm for drought tolerance, conventional breeding strategies, and marker-assisted and genomic-assisted breeding and development of transgenic maize. As a comprehensive understanding of the effects of drought stress, adaptive strategies and potential breeding tools is the prerequisite for any sound breeding plan, this brief addresses these aspects.

With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

Download or read book Crop Responses and Adaptations to Temperature Stress written by Amarjit Basra and published by CRC Press. This book was released on 2023-04-28 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examine the ways in which various plants respond when exposed to high and low temperatures! The growing demand for food makes breeding for high-yielding crops with built-in resistance against environmental constraints one of the most important challenges for plant breeders today. Crop Responses and Adaptations to Temperature Stress investigates the adaptive mechanisms plants have evolved in response to unfavorable temperature conditions. It describes gene transfer technology and other tolerance improvement techniques that aid in developing stress-tolerant plants. Adverse environmental stress conditions, such as extreme temperatures, affect the productivity of important world food crops by inhibiting plant growth and development. Crop Responses and Adaptations to Temperature Stress provides valuable information on the mechanisms of stress tolerance in plants that encourage growth and enhance yield performance. Agriculture professionals, researchers, and plant breeders will benefit from the ideas shared on such topics as: mechanisms of chilling injury and tolerance injury and acclimation of root system functions during chilling temperatures mechanisms of cold acclimation signal transduction under low-temperature stress mechanisms of thermotolerance in crops control of the heat shock response in crop plants the effects of heat stress on cereal yield and quality Crop Responses and Adaptations to Temperature Stress presents detailed discussions on the effects and outcomes of crop exposure to low and high temperatures. The textual information is liberally supplemented with visual representations of field experiment data as well as comprehensive tables and schematic drawings. In addition to a detailed review of current knowledge on the molecular biology of plant responses to temperature stress and an introduction to biotechnological advances in improving crop tolerance, Crop Responses and Adaptations to Temperature Stress suggests avenues for further study and speculates on the implications of such work for the future of food production.
