To face the double pressures from the changing environment and increasing demand of the growing population globally, maize plays an essential role in securing food safety due to its strong adaptability. With climate change, the severity of extreme environmental stresses is projected to be more frequent, which affects maize growth, physiological processes, and productivity. It is important to explore the physiological mechanisms and regulatory measures in response to abiotic stresses. The interactions between crop and environmental stresses are multistep and complex. The stress resistance response of maize is still an extremely complicated process. Studies on responses of maize growth, yield, or quality under stress conditions are growing exponentially, but the description at a physiological or biochemical level is still unclear. In addition, new knowledge of maize hybrids with adversity resistance has not been deeply excavated. Hence, it is necessary to capture current knowledge on the impact of abiotic stress on maize, especially the mechanisms and regulation of maize responses under multiple stresses, and to provide potential solutions that will ensure a sustainable supply of nutritious food to meet the demand from an increasing population under a changing climate.

This book highlights modern methods and strategies to improve cereal crops in the era of climate change, presenting the latest advances in plant molecular mapping and genome sequencing. Spectacular achievements in the fields of molecular breeding, transgenics and genomics in the last three decades have facilitated revolutionary changes in cereal- crop-improvement strategies and techniques. Since the genome sequencing of rice in 2002, the genomes of over eight cereal crops have been sequenced and more are to follow. This has made it possible to decipher the exact nucleotide sequence and chromosomal positions of agroeconomic genes. Most importantly, comparative genomics and genotyping-by-sequencing have opened up new vistas for exploring available biodiversity, particularly of wild crop relatives, for identifying useful donor genes.

Agriculture has shaped our planet into the world we know, but its continued success is threatened by changing weather patterns. Climate change is a diverse, multifactorial phenomenon and the agronomic strategies we employ to combat its effects need to be case-specific, with significant regional differences. With two major sections, the first explaining the challenges posed by climate change and the second reviewing the current research avenues employed, this book combines detailed discussion of physiological plant responses with practical experience on crop stress management and breeding. Using a number of illustrative case studies, it discusses how the stresses resulting from climate change could be overcome by assessing, measuring and predicting environmental changes and stresses, and identifying opportunities for adapting to multifactorial change. A global effort to combine climate change science with policy is desperately needed. Climate change will continue to pose many challenges to agriculture in the future but by taking an integrative approach to predicting and adapting to change, this book will inspire researchers to turn those challenges into opportunities.

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.

Not all environmental stresses are covered, omitting those for which little can be said today on practical breeding solutions.
