The effector MgCRT1 of Meloidogyne graminicola targets the pathogenesis-related (PR) protein OsPR1#101 to facilitate nematodes parasitism in rice

Abstract

The root-knot nematodes Meloidogyne graminicola (M. graminicola) are an important pathogenic nematode that harms rice. During infection, plant parasitic nematodes use needles to penetrate the plant cell wall, and secrete effectors into cells, thus destroying the root system's ability to absorb water and nutrients. Rice root-knot nematode disease is difficult to control once established, with traditional chemical methods prone to pollution and slow efficacy. Exploring the pathogenic mechanism of effector proteins of plant parasitic nematodes will provide a solid theoretical basis for the utilization of plant innate immunity and genetic engineering or molecular breeding of nematode resistance.
