Root-knot and cyst nematode parasitism genes: the molecular basis of plant parasitism.
Roundworms of the Nematoda comprise one of the largest animal phyla on Earth (1). They inhabit diverse terrestrial and aquatic niches through adaptations of a spectrum of trophic groups, including parasites that threaten human, animal and crop plant health. The most well-known nematode, Caenorhabditis elegans, is a native soil-dwelling microbivore that has emerged as a premier model for animal ...
متن کامل1982 Engineering durable root-knot nematode resistance in crops by RNAi silencing of a root-knot nematode parasitism gene
Secreted proteins coded by parasitism genes expressed in esophageal gland cells mediate infection and parasitism of plants by root-knot nematodes. An essential parasitism gene, designated as 16D10, encodes a conserved root-knot nematode secretory peptide that stimulates root growth and functions as a ligand for a plant transcription factor. Plants were engineered to silence this parasitism gene...
متن کاملGenetic analysis of parasitism in the soybean cyst nematode Heterodera glycines.
A genetic analysis of parasitic ability in the soybean cyst nematode Heterodera glycines was performed. To identify and characterize genes involved in parasitism, we developed three highly inbred H. glycines lines, OP20, OP25 and OP50, for use as parents for controlled crosses. Through these crosses, we have identified genes in the inbred parents that control reproduction of the nematode on hos...
متن کاملThe amino acid permeases AAP3 and AAP6 are involved in root-knot nematode parasitism of Arabidopsis.
The root-knot nematode, Meloidogyne incognita, is an obligate parasite which depends entirely on the host plant for its nutrition. Root-knot nematodes induce the formation of a highly specialized feeding site consisting of several giant cells surrounded by a network of vascular tissues. Nutrients, including amino acids and sugars, are transferred apoplastically from the vascular tissues to the ...
متن کاملAn Approach to the Parasitism Genes of the Root Knot Nematode
Plant parasitic nematodes which are highly successful parasites evolved a very specialized feeding relationship with the host plant to cause the destructive root-knot disease. They initiate their parasitic relationship with the host by releasing their secretions into root cells which in turn stimulate the root cells of the host to become specialized feeding cells which are considered as the sin...
