This volume is an exhaustive source of information on the control and regulation of flowering. It presents data on the factors controlling flower induction and how they may be affected b climate and chemical treatments. For each plant, specific information is provided on all aspects of flower development, including sex expression, requirements for flowering initiation and development, photoperiod, light density, vernalization, and other temperature effects and interactions. Individual species are described from the standpoint of juvenility and maturation, morphology, induction and morphogenesis to anthesis. All information is presented alphabetically for easy reference.

Finding and understanding the precise meaning of many terms in genetics is crucial to understan...
Cotton is the most important natural fiber crop of our planet, which provides humanity with cloth and vegetable oil, medicinal compounds, meal and hull for livestock feed, energy sources, organic matter to enrich soil, and industrial lubricants. Therefore, cotton research to improve sustainable cotton production worldwide is the vital task of scientific community to address the increasing demands and needs for cotton products. This Cotton Research book presents readers updated information and advances in current cotton science investigations. Chapters of this book provide the latest developments on cotton research and cover topics on cotton research infrastructure, physiology and agronomy, breeding and genetics, modern biotechnology, genomics and molecular breeding, crop management, and cotton-based product and textile researches.
A rare norovirus (NoV) genotype GII.17 has recently emerged and rapidly became predominant in most East Asian countries in the winters of 2014-2015. In this study, we report the diversity of NoV GII.17 in detail; a total of 646 GII.17 sequences obtained during 1978-2015 were analyzed and subjected to meta-analysis. At least five major recombinant GII.17 clusters were identified. Each recombinant variant group appeared to have emerged following the time order: GII.P4-GII.17 (1978-1990), GII.P16-GII.17 (2001-2004), GII.P13-GII.17 (2004-2010), GII.Pe-GII.17 (2012-2015) and GII.P3-GII.17 (2011-2015). The newly emerged GII.P3-GII.17 variant, which exhibited significant sequence and structure variations, is evolving toward a unique lineage. Our results indicate that circulation of GII.17 appears to change every 3-5 years due to replacement by a newly emerged variant and that the evolution of GII.17 is sequentially promoted by inter-genotype recombination, which contributes to the exchange between non-GII.17 and GII.17 RdRp genes and drives the evolution of GII.17 capsid genes.
This book comprises the best potato seed production practices and includes details on potato cultivation, classification, and the main structural elements of the successive stages of potato seed production. It presents potato varieties from Russian originators, describes modern technologies involved in the process of potato seed production, and presents special aspects of phytosanitary and process regulations for the cultivation of high-quality potato seed. Additionally, the authors illustrate the statutory regulation of salable quality of potato seed: purity of variety, diseases, pests, and defects. The authors identify Russian quality control methods and certification of potato seed, and consider the packaging and labeling of potato seed that is held for sale. Finally, the authors also clarify the features of foreign potato seed certification systems.
This book reviews the latest advances in multiple fields of plant biotechnology and the opportunities that plant genetics, genomics and molecular biology have offered for agriculture improvement. Advanced technologies can dramatically enhance our capacity in understanding the molecular basis of traits and utilizing the available resources for accelerated development of high yielding, nutritious, input-use efficient and climate-smart crop varieties. In this book, readers will discover the significant advances in plant genetics, structural and functional genomics, trait and gene discovery, transcriptomics, proteomics, metabolomics, epigenomics, nanotechnology and analytical & decision support tools in breeding. This book appeals to researchers, academics and other stakeholders of global agriculture.
Meeting future food needs without compromising environmental integrity is a central challenge for agriculture globally but especially for the Asia Pacific region – where 60% of the global population, including some of the world’s poorest, live on only 30% of the land mass. To guarantee the food security of this and other regions, growers worldwide are rapidly adopting genetically modified (GM) crops as the forerunner to protect against many biotic and abiotic stresses. Asia Pacific countries play an important role in this, with India, China and Pakistan appearing in the top 10 countries with acreage of GM crops, primarily devoted to Bt cotton. Genetically Modified Crops in Asia Pacific d...
