Systematics Of Root Knot Nematodes Nematoda Meloidogynidae

This book is the first complete illustrated compendium of root-knot nematode species from the genus Meloidogyne including 97 species descriptions with comprehensive diagnoses, information on biology, plant-hosts, pathogenicity, symptoms, distribution and biochemical and molecular diagnostics.

"Root-knot nematodes of the genus Meloidogyne represent one of the most damaging and agricultural important group of plant-parasitic nematodes. These nematodes are obligate sedentary endoparasites infecting most species of higher plants and have a cosmopolitan distribution. Annual worldwide economic losses due to nematode infection of crops have been estimated at several hundred billion US dollars. This book is the first complete illustrated compendium of root-knot nematode species and contains 98 species descriptions with comprehensive diagnoses, information on biology, plant-hosts, pathogenicity, symptoms, distribution and biochemical and molecular diagnostics. It also includes introductions into morphology, biology, biogeography, genomics, phylogeny and host-parasite relationships of root-knot nematodes"--

This book provides an overview (chapter 1) of the general biology, ecology and economic importance of root-knot nematodes (Meloidogyne spp.), and covers in detail the following: general morphology (chapter 2); taxonomy, identification and principal species (chapter 3); biochemical and molecular identification (chapter 4); molecular taxonomy and phylogeny (chapter 5); hatch and host location (chapter 6); invasion, feeding and development (chapter 7); reproduction, physiology and biochemistry (chapter 8); survival mechanisms (chapter 9); interactions with other pathogens (chapter 10); population dynamics and damage levels (chapter 11); sampling (chapter 12); mechanisms and genetics of resistance (chapter 13); development of resistant cultivars (chapter 14); plant biotechnology and control (chapter 15); complete sequence of the genomes of M. incognita and M. hapla (chapter 16); biological control using microbial pathogens, endophytes and antagonists (chapter 17); current and future management strategies in intensive crop production systems (chapter 18); and current and future management strategies in resource-poor farming (chapter 19).

The genus Meloidogyne Göldi, 1892, or root-knot nematodes, represent a relatively small but economically important group of obligate plant pathogens. They are distributed worldwide and parasitize on almost every higher plant species. While reproducing and feeding within roots, they induce galls or root-knots and disorder the physiology of the infected plant, reducing crop yield and product quality. More than eighty nominal species have been described worldwide, while twenty species have been detected in Europe so far. This book includes a historical review on the genus, followed by a revision of the European species, and completed with a study on one of the most characteristic morphological structures within the genus: the perineal pattern.

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.

Volume 8 in the series, appearing in two parts, A and B, deals with the systematics of cyst nematodes of the subfamily Heteroderinae. Cyst nematodes are important pathogens causing extensive damage and significant yield loss to many crops in both temperate and tropical regions.

Nematodes are one of the most abundant groups of invertebrates on the face of the earth. Their numbers are estimated to range from 1000 per cm2 in the sand-covered hydrogen sulphide ‘black zone’ beneath the ocean floors to 1.2 billion in a single hectare of soil. Estimates for their species diversity range from 100 000 to 10 million. The past history of nematodes is a mystery, since very few fossils have been discovered. This book establishes a solid base in palaeonematology with descriptions of 66 new fossil species and accounts of all previous fossil and subfossil nematodes from sedimentary deposits, coprolites, amber and mummies. It shows how nematode fossils can be used to establish lineages at various locations and time periods in the earth’s history and when nematodes entered into symbiotic and parasitic associations with plants and animals.

This volume gives a detailed morphology of the dorylaims and provides a thorough overview of their feeding behaviour, reproduction, ecology, and diversity. You will learn what dorylaims are like and how they live.
