Book Description
The germplasm sources highly resistant to Meloidogyne incognita (Southern root-knot nematode) in Upland cotton (Gossypium hirsutum L) contain the resistance QTLs qMI-C11 and qMi-C14. Previous research documented resistance expressed at two stages of nematode development, and later research documented an epistatic interaction between the two QTLs, both of which suggest the QTLs have different modes of action. Our experiments demonstrated that qMi-C11 reduces the number of galls and egg masses, total egg production, and eggs/egg mass whereas qMi-C14 reduces the number of egg masses, total egg production, and eggs/egg mass without reducing galling. Fusarium oxysporum f. sp. vasinfectum (Fov) interacts with M. incognita resulting in increased Fusarium wilt (FW), therefore, we tested the effect of the nematode resistance QTLs on the severity of FW. A reduction of plant growth and an increase in FW severity was seen on all genotypes regardless of nematode resistance QTLs when coinfected with Fov and M. incognita. FW has been reported more frequently in Georgia in recent years, which suggests that something affecting the disease complex may have changed. In 2015 and 2016, a survey of Georgia cotton fields was conducted. The survey showed that Fov race 1 is still the dominant race, but Fov genotypes not previously reported in Georgia were found. Additionally, many instances of FW in Georgia are due to Fov interacting with Belonolaimus longicaudatus and not M. incognita as previously believed.

Nematode Interactions

Pages : 388
Book Description
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.

Book Description
Compendium of Cotton Diseases, Second Edition provides practical, up-to-date information on the diagnosis and control of cotton diseases worldwide. This new edition begins with an overview of the origin and evolution of cultivated cotton and a description of the growth and development of the plant, which is fundamental in disease diagnosis and effective management strategies. Expanded disease sections include detailed pathogen descriptions, characteristic symptoms that occur, the disease cycle, and control information. Includes twice as many color photographs as the first edition.Additional improvements include:-greater attention to noninfectious disorders, including nutritional disorders, herbicide injury and toxicity, and environmental stresses.-sections on common disease interactions, host plant resistance to pathogens, and general principles of disease management in integrated production systems.
Plant Parasitic Nematodes

Languages : en
Pages : 529
Book Description
Plant Parasitic Nematodes, Volume III provides a comprehensive discussion of the different advances in plant nematology. This includes biochemical techniques to taxonomy and innovation in transmission and scanning electron microscopy technology. It explains a broadened basis for understanding nematode physiology and behavior and the sensory mechanisms that govern nematode actions and plant host-nematode interactions. The book discusses the development of modern approaches to the evaluation and reduction of crop losses. The emphasis of this volume is on plant parasites and insights gained through research on other nematodes. In particular, the book explains the anatomical, developmental, behavioral, and genetic studies on the free-living nematode Cenorhabditis elegans, which is a widely used laboratory model for examining various biological problems. The information provided by various researches on C. elegans increases our understanding about the relevance of nematodes to general biological processes in higher organisms, including man. The book is divided into 19 chapters which cover the following concepts of plant nematology: biochemistry, cytochemistry, and genetics; morphology and function; host-parasite relations; and evaluation and control of crop losses. The present volume is an excellent reference for students, lecturers, and research professionals in plant parasitology and related fields.
