Abstract

Root-knot nematode (RKN), an important pathogenic nematode, causes huge economic losses to agricultural production. The second-stage juveniles of root knot nematode invade root of host plants, then inject secretions of their esophageal gland through their stylets, which stimulate the formation of giant cells and thus root knots in their hosts. The proteins synthesized in the esophageal glands have been shown to play important roles in the interactions of root-knot nematode with their host plants. We found that, MiPDCD6 from RKN could interact with a tomato transcription factor LeMYB330 and proposed a role of for how MiPDCD6 from RKN to modulate the apoptosis process of giant cells vacuolation in the host.
