Management strategies for control of soybean cyst nematode and their effect on the nematode community
Soybean cyst nematode (SCN), Heterodera glycines, is the major yield-limiting pathogen on soybean and various plant-parasitic nematodes can damage corn. Additionally, the nematode community is a useful bioindicator for soil health. In chapter 1, relevant research is reviewed. Chapter 2 describes …

An investigation into the potential of crude and partially separated material of selected non–crop plant species as control agents of root–knot nematodes (Meloidogyne incognita) in tomato
Plant-parasitic nematodes (PPN) are a serious problem in vegetable production and can cause severe damage to several crops. In rural, low-input farming nematode damage is much higher and yields can be completely destroyed. Some Commercial nematicides have been withdrawn from the market due to …

The role of heterodera glycines biotin synthase in the nematode-soybean interactions
Heterodera glycines, the soybean cyst nematode (SCN), is a plant-parasitic nematode capable of manipulating host plant biochemistry and development. Many studies have shown that the nematode has acquired genes from bacteria via horizontal gene transfer events (HGTs) that have the potential to …

Evaluation of resistance in Glycine max to Fusarium virguliforme and in perennial Glycine species to Phakopsora pachyrhizi and Heterodera glycines
… soybean rust, and infection by soybean cyst nematode caused by fungal pathogens Fusarium virguliforme and Phakopsora pachyrhizi and the plant-parasitic nematode Heterodera glycines, respectively, are three major yield-limiting problems. Soybean cultivars have a narrow genetic base due to …

Plant-parasitic nematodes: from genomics to functional analysis of parasitism genes
Nematodes (roundworms) belong to the largest phylum on earth. The numerous species inhabit practically all ecological niches, including plants. Plant-parasitic species live on plant roots, causing substantial damage to the plant and hampering its development. As such, they cause gigantic economical …

Characterization of horizontally transferred vitamin B biosynthesis genes in the soybean cyst nematode, Heterodera glycines
… glycines), commonly known as the soybean cyst nematode (SCN), is an obligate plant parasite and a major pest of soybean. It is highly adapted to manipulate and parasitize host plants. It possesses parasitism/effector genes that enable it to developmentally alter host cells and establish feeding …

Analysis of Genes Expressed by Meloidogyne incognita Males: Generation of ESTs and Comparative Genomics
… knowledge that has revolutionized the study of plant parasitic nematode biology and disease. Meloidogyne incognita is one of the most devastating plant parasitic nematodes worldwide and has proven to be a prime example of the utility of comparative genomics in the investigation of plant …

Molecular analysis of migratory plant-parasitic nematodes with a focus on plant cell wall modifying enzymes
Plant-parasitic nematodes cause a considerable amount of crop damage worldwide. These nematodes all have a stylet to damage plant cells mechanically, but through which they also secrete proteins important for their infection process. Most studies on genes encoding these so-called parasitism …

Developmental biology of heterodera glycines (soybean cyst nematode) and other plant - parasitic nematodes
Nematodes are unsegmented round worms with a pseudocoelomate body cavity. Nematodes are omnipresent in nature. Most are free-living, living as bacterial or fungal feeders, while many nematodes species are parasitic to animals or plants and have a huge impact on human health and agriculture …

Developing a genetic toolkit for plant-parasitic nematodes
Nematodes belong to one of the most diverse phyla on the planet. Most nematodes are free living and feed on bacteria, fungi, and protozoa. Plant-parasitic lifestyles are relatively rare in terms of numbers, however, through their parasitism these nematodes have a substantial impact on agriculture. …
