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.

Available in PDF, EPUB and Kindle. Book excerpt: Responses of Plants to Environmental Stresses, Second Edition, Volume II: Water, Radiation, Salt, and Other Stresses focuses on the effects of stresses on plants. This book discusses how stresses produce their damaging effects and how living organisms defend themselves against stresses. Organized into six parts encompassing 12 chapters, this edition starts with an overview of the various responses of plants to the severities of all the other environmental stresses, with emphasis on the physical and biological stresses and strains. This text then describes water stress in plants, which arise either from an excessive or from an insufficient water activity in the plant's environment. Other chapters consider the resistance to drought stress of plants. This book discusses as well the effects of flooding, which replaces gaseous air by liquid water. The final chapter deals with the comparative stress responses of plants. This book is a valuable resource for plant biologists.

Available in PDF, EPUB and Kindle. Book excerpt: Learn how to best improve yield in cereal plants—even in dry conditions The impact of drought on crop production can be economically devastating. Drought Adaptation in Cereals provides a comprehensive review of the latest research on the tolerance of cereal crops to water-limited conditions. Renowned experts extensively describe basic concepts and cutting-edge research results to clearly reveal all facets of drought adaptation in cereals. More than simply a fine reference for plant biology and plant improvement under water-limited conditions, this book spotlights the most relevant biological approaches from plant phenotyping to functional genomics. The need to understand plant response to the lack of water is integral to forming strategies to best manage crops. Drought Adaptation in Cereals starts by offering an overview of the biological basis and defines the adaptive mechanisms found in plants under water-limited conditions. Different approaches are presented to provide understanding of plant genetics basics and plant breeding, including phenotyping, physiology, and biotechnology. The book details drought adaptation mechanisms at the cellular, organ, and entire plant levels, focusing on plant metabolism and gene functions. This resource is extensively referenced and contains tables, charts, and figures to clearly present data and enhance understanding. After a foreword by J. O'Toole and a prologue by A. Blum, Drought Adaptation in Cereals presents a full spectrum of informative topics from other internationally respected scientists. These include: drought’s economic impact (P. Heisey) genotype-by-environment interactions (M. Cooper) secondary traits for drought adaptation (P. Monneveux) leaf growth (F. Tardieu) carbon isotope discrimination (T. Condon) drought adaptation in barley (M. Sorrells), maize (M. Sawkins), rice (R. Lafitte), sorghum (A. Borrell) and wheat (M. Reynolds) carbohydrate metabolism (A. Tiessen) the role of abscisic acid (T. Setter) protection mechanisms and stress proteins (L. Mtwisha) genetic basis of ion homeostasis and water deficit (H. Bohnert) transcriptional factors (K. Yamaguchi-Shinozaki) resurrection plants (D. Bartels) Drought Adaptation in Cereals is a unique, vital reference for scientists, educators, and students in plant biology, agronomy, and natural resources management.

Book excerpt: Maize production is limited agronomically by the availability of water and nutrients during the growing season. Of these two limiting factors, water availability is predicted to increase in importance as climate change and the growing urban landscape continue to stress limited supplies of freshwater. Historically, efforts to breed maize for water-limited environments have been extensive; especially in the areas of root architecture and flowering physiology. As progress has been made and new traits have been discovered and selected for, the different responses to drought stress at specific developmental stages of the maize plant have been selected as a whole when drought tolerance is evaluated. Herein we attempt to define the characteristics of the maize drought response during different developmental stages of the maize plant that can be altered through plant breeding. Towards breeding for drought tolerance, 400 inbred lines from a diversity panel were amplified and sequenced at the ZmLOX4 and ZmLOX5 loci in an effort to characterize their linkage disequilibrium and genetic diversity. Understanding these characteristics is essential for an association mapping study that accompanies this project, searching for novel and natural allelic diversity to improve drought tolerance and aflatoxin resistance in maize. This study is among the first to investigate genetic diversity at important gene paralogs ZmLOX4 and ZmLOX5 believed to be highly conserved among all Eukaryotes. We show very little genetic diversity and very low linkage disequilibrium in these genes, but also identified one natural variant line with knocked out ZmLOX5, a variant line missing ZmLOX5, and five line variants with a duplication of ZmLOX5. Tajima's D test suggests that both ZmLOX4 and ZmLOX5 have both been under neutral selection. Further investigation of haplotype data revealed that ZmLOX12, a member of the ZmLOX family, showed strong LD that extends much further than expected in maize. Linkage disequilibrium patterns at these loci of interest are crucial to quantify for future candidate gene association mapping studies. Knockout and copy number variants of ZmLOX5, while not a surprising find, are under further investigation for crop improvement.

Book excerpt: The objectives of this investigation were to test the genotypic differences in drought tolerance, estimate the heritability, and to evaluate the role of gca and sca of inbreds in hybrid under water stress. The main results were:1-Hybrids G507AxG278, L81BxG278 and G507AxL 81B were high tolerance to drought.2-Correlation between grain yield and yield components were higher under stress than non-drought in most cases. 3-All studied yield and yield components showed high broad- sense heritability estimates under stress and non-stress treatments in both seasons.4- The expected gain from direct selection for grain yield under stressed or non-stressed environments would improve the trait under consideration in a way better than the indirect selection for any other traits. 5-Inbreds L 81B, G 278 and G 507A showed positive and significant GCA effects for grain and ear yield and most of yield components traits under stress or non-stress treatments
