Book Synopsis Dwarfing Genes in Spring Wheat by : Amber Marie Robbins
Download or read book Dwarfing Genes in Spring Wheat written by Amber Marie Robbins and published by . This book was released on 2009 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rht-B1b and Rht-D1b (formerly Rht1 and Rht2) dwarfing genes have been used extensively since the Green Revolution to reduce height and increase yield in hexaploid wheat (Triticum aestivum L.). They have been used in the development of hundreds of modern cultivars. Semi-dwarf wheat varieties containing these GA-insensitive dwarfing genes generally yield more grain than their tall Rht-B1a and Rht-D1a (formerly rht1 and rht2) counterparts. However, Rht-B1b and Rht-D1b are better adapted to high-input environments and can reduce plant performance under adverse conditions such as heat or drought stress. In such environments, Rht8, a GA-sensitive dwarfing gene, could prove beneficial. This study aimed to assess agronomic performance of Rht8 compared to Rht-B1b and Rht-D1b using near-isogenic lines of the six possible genotypes (Rht-B1b, Rht-B1a, Rht-D1b, Rht-D1a, Rht8, and rht8) in four different spring wheat backgrounds. Field trials were conducted during the 2008 and 2009 growing seasons in Bozeman and Kalispell, MT. Traits measured included plant height, coleoptile length, stem solidness, days to heading, yield, flag leaf characteristics, harvest index, and others. Measurements were taken from field trials except coleoptile length, which was grown in a temperature and light controlled growth chamber. Rht genotype had a significant effect on plant height, coleoptile length, and yield. Height reductions of 20.5%, 22.4%, and 10.1% were observed for Rht-B1b, Rht-D1b, and Rht8, respectively. Rht8 showed no significant effect on coleoptile length, while Rht-B1b and Rht-D1b exhibited reductions in coleoptile length of 21.3% and 22.8%. Rht-B1b and Rht-D1b both showed a 6.1% and 14.1%. increase in yield potential. In contrast, Rht8 showed a yield decrease of 5.3%. Of most interest to plant breeders are those traits that effect yield. Yield is a complex, multi-genic trait that is affected by many plant characteristics and environmental factors. Because of the quantitative nature of yield, it is impacted by not only the presence of dwarfing genes, but also genetic background and environmental variables. This study suggests that Rht-B1b and Rht-D1b are superior, in terms of yield potential, to Rht8. However, additional evaluation of Rht8 in differing environments is needed to elucidate its precise effects on yield and other agronomic traits.
Book Synopsis Genes Controlling Coleoptile Length and Seedling Emergence in Wheat and Their Role in Plant Height by : Khalid Ali Mohammed Elbudony
Download or read book Genes Controlling Coleoptile Length and Seedling Emergence in Wheat and Their Role in Plant Height written by Khalid Ali Mohammed Elbudony and published by . This book was released on 2017 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finding alternate dwarfing gene system by modulating auxin distribution, a 'true' wheat ortholog (TaABCB19) of the Arabidopsis ABCB19 has shown to be involved in regulating plant height via modulating auxin transport in the stem. True ortholog of AtPGP19 has been identified in various monocots and dicots species. The smallest genomic copy of PGP19 is present in barley and quite largely in Soybean, the variation in gene size ranged from7496 bp to 6628 bp. The gene structure showed similarities between monocots and dicots, with highly conservative exonic region 1 and 8. The TaABCB19 RNAi plant resulted in reduced height up to 48%, and more than doubled spikelet number. This studies furthers the scientific understanding of the genetic relationship of plant height with other growth related traits for selecting and combining desirable traits for wheat improvement.

Book Synopsis Advances in Wheat Genetics: From Genome to Field by : Yasunari Ogihara
Download or read book Advances in Wheat Genetics: From Genome to Field written by Yasunari Ogihara and published by Springer. This book was released on 2015-09-15 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings is a collection of 46 selected papers that were presented at the 12th International Wheat Genetics Symposium (IWGS). Since the launch of the wheat genome sequencing project in 2005, the arrival of draft genome sequences has marked a new era in wheat genetics and genomics, catalyzing rapid advancement in the field. This book provides a comprehensive review of the forefront of wheat research, across various important topics such as germplasm and genetic diversity, cytogenetics and allopolyploid evolution, genome sequencing, structural and functional genomics, gene function and molecular biology, biotic stress, abiotic stress, grain quality, and classical and molecular breeding. Following an introduction, 9 parts of the book are dedicated to each of these topics. A final, 11th part entitled “Toward Sustainable Wheat Production” contains 7 excellent papers that were presented in the 12th IWGS Special Session supported by the OECD. With rapid population growth and radical climate changes, the world faces a global food crisis and is in need of another Green Revolution to boost yields of wheat and other widely grown staple crops. Although this book focuses on wheat, many of the newly developed techniques and results presented here can be applied to other plant species with large and complex genomes. As such, this volume is highly recommended for all students and researchers in wheat sciences and related plant sciences and for those who are interested in stable food production and food security.
Download or read book Crop Photosynthesis written by N.R. Baker and published by Elsevier. This book was released on 2013-10-22 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since photosynthetic performance is a fundamental determinant of yield in the vast majority of crops, an understanding of the factors limiting photosynthetic productivity has a crucial role to play in crop improvement programmes. Photosynthesis, unlike the majority of physiological processes in plants, has been the subject of extensive studies at the molecular level for many years. This reductionist approach has resulted in the development of an impressive and detailed understanding of the mechanisms of light capture, energy transduction and carbohydrate biosynthesis, processes that are clearly central to the success of the plant and the productivity of crops. This volume examines in the widest context the factors determining the photosynthetic performance of crops. The emphasis throughout the book is on the setting for photosynthesis rather than the fundamental process itself. The book will prove useful to a wide range of plant scientists, and will encourage a more rapid integration of disciplines in the quest to understand and improve the productivity of crops by the procedures of classical breeding and genetic manipulation.

Download or read book Selection Methods in Plant Breeding written by Izak Bos and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our requirement for plant breeders to be successful has never been greater. However one views the forecasted numbers for future population growth we will need, in the immediate future, to be feeding, clothing and housing many more people than we do, inadequately, at present. Plant breeding represents the most valuable strategy in increasing our productivity in a way that is sustainable and environmentally sensitive. Plant breeding can rightly be considered as one of the oldest multidisciplin ary subjects that is known to humans. It was practised by people who first started to carry out a settled form of agriculture. The art, as it must have been at that stage, was applied without any formal underlying framework, but achieved dramatic results, as witnessed by the forms of cultivated plants we have today. We are now learning how to apply successfully the results of yet imperfect scientific knowledge. This knowledge is, however, rapidly develop ing, particularly in areas of tissue culture, biotechnology and molecular biology. Plant breeding's inherent multifaceted nature means that alongside obvious subject areas like genetics we also need to consider areas such as: statistics, physiology, plant pathology, entomology, biochemistry, weed science, quality, seed characteristics, reproductive biology, trial design, se lection and computing.

Book Synopsis Salinity and Water Stress by : M. Ashraf
Download or read book Salinity and Water Stress written by M. Ashraf and published by Springer Science & Business Media. This book was released on 2008-12-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salinity and water stress limit crop productivity worldwide and generate substantial economic losses each year, yet innovative research on crop and natural resource management can reveal cost-effective ways in which farmers can increase both their productivity and their income. Presenting recent research findings on salt stress, water stress and stress-adapted plants, this book offers insights into new strategies for increasing the efficiency of crops under stressful environments. The strategies are based on conventional breeding and advanced molecular techniques used by plant physiologists, and are discussed using specific case studies to illustrate their potential. The book emphasizes the effects of environmental factors on specific stages of plant development, and discusses the role of plant growth regulators, nutrients, osmoprotectants and antioxidants in counteracting their adverse affects. Synthesising updated information on mechansisms of stress tolerance at cell, tissue and whole-plant level, this book provides a useful reference text for post graduate students and researchers involved in the fields of stress physiology and plant physiology in general, with additional readership amongst researchers in horticulture, agronomy, crop science, conservation, environmental management and ecological restoration.
