Book Synopsis Diversidade genética entre acessos de algodão determinada por marcadores moleculares microssatélites e caracteristicas agronômicas by : T.de C. COUTINHO
Download or read book Diversidade genética entre acessos de algodão determinada por marcadores moleculares microssatélites e caracteristicas agronômicas written by T.de C. COUTINHO and published by . This book was released on 2006 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: O conhecimento sobre a variabilidade genética é um importante recurso em programas de melhoramento. A variação genética em algodão tem sido extensivamente estudada por características morfológicas e marcadores moleculares. Os marcadores microssatélites ou SSR (Sequências Simples Repetitivas) são seqüências de pequenas repetições em pares de bases distribuídos ao longo do genoma. A identificção genotípica a partir destes marcadores pode diagnosticar marcas polimórficas existentes no genoma, que poderão auxiliar na seleção de genes envolvidos em características agronômicas. O presente trabalho teve por objetivo avaliar a diversidade genética entre 32 acessos pertencentes ao banco ativo de germoplasma da EPAMIG por meio de microssatélites e, correlacionar características morfológicas aos dados obtidos pelos marcadores. Dos 37 loci de microsatélite estudados, o número de alelos por locus variou de 1 a 7, com uma média de 2,86 alelos por locus. A maior taxa de heterozigosidade foi de 0,15 para o acesso Dendera, enquanto que, a menor taxa de heterozigosidade foi de 0,05 para os acessos T-7044 e COKER-310. O dendrograma gerado com dados morfológicos permitiu inferir que o acesso T-295-1-1 foi o mais divergente, diferente do obtido por marcadores molecu lares onde os acessos mais divergentes foram Dendera e Giza 80. As correlações entre os dados morfológicos e de marcadores microssatélites não apresentaram significância, demonstrando que nenhum dos marcadores microssatélites foi capaz de detectar alguma marca relacionada às características morfológicas avaliadas.
Book Synopsis Integrated Management and Biocontrol of Vegetable and Grain Crops Nematodes by : A. Ciancio
Download or read book Integrated Management and Biocontrol of Vegetable and Grain Crops Nematodes written by A. Ciancio and published by Springer Science & Business Media. This book was released on 2007-12-08 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second volume of the IMPD series describes aspects related to the most important phytoparasitic nematodes, considering the integration of biological control methods with other management practices and technologies, including the use of predatory nematodes and microbial rhizosphere antagonists. A focus is given on regional issues. A review on nematode management in cotton is integrated by a chapter on management of nematodes on wheat. New technologies are also revised.
Book Synopsis Plant Nematology, 3rd Edition by : Roland N. Perry
Download or read book Plant Nematology, 3rd Edition written by Roland N. Perry and published by CABI. This book was released on 2024-07-12 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.
Book Synopsis Nematode Interactions by : M. Wajid Khan
Download or read book Nematode Interactions written by M. Wajid Khan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.
