Root-knot nematodes (RKN) infect a large number of plant species triggering the formation of galls by inducing vascular cells to reenter the cell cycle. These nematodes infect the host root and usurp the plant cell cycle machinery by inducing multinucleate giant-feeding cells surrounded by asymmetrically dividing neighboring cells. Cell cycle...

Although generally unnoticed, nearly all crop plants have one or more species of nematodes that feed on their roots, frequently causing tremendous yield losses. The group of sedentary nematodes, which are among the most damaging plant-parasitic nematodes, cause the formation of special organs called nematode feeding sites (NFS) in the root...

Plant-parasitic nematodes produce at least one structurally unique class of small helix-rich retinol-and fatty-acid-binding proteins that have no counterparts in their plant hosts. Herein we describe a protein of the plant-parasitic root-knot nematode Meloidogyne javanica, which is a member of the nematode-specific fatty-acid- and...
