Root-Knot-Nematodes are obligate plant parasites able to infect a large panel of cultivated plants. These parasites have the ability to induce redifferentiation of five to seven root cells into specialized giant cells, hypertrophied, multinucleated and metabolically overactive. These giant cells form the feeding site upon which nematodes feed...

BackgroundRoot-knot nematodes (RKN), genus Meloidogyne, are plant parasitic worms that have the ability to transform root vascular cylinder cells into hypertrophied, multinucleate and metabolically over-active feeding cells. Redifferentiation into feeding cells is the result of a massive transcriptional reprogramming of root cells targeted by...

Root knot nematodes (RKN) are root parasites that induce the genetic reprogramming of vascular cells into giant feeding cells and the development of root galls. MicroRNAs (miRNAs) regulate gene expression during development and plant responses to various stresses.Disruption of post-transcriptional gene silencing in Arabidopsis ago1 or ago2...
