説明
<jats:p>The root-knot nematode<jats:italic>Meloidogyne chitwoodi</jats:italic>secretes effector proteins into the cells of host plants to manipulate plant-derived processes in order to achieve successful parasitism. Mc1194 is a<jats:italic>M. chitwoodi</jats:italic>effector that is highly expressed in pre-parasitic second-stage juvenile nematodes. Yeast two-hybrid assays revealed Mc1194 specifically interacts with a papain-like cysteine protease (PLCP), RD21A in<jats:italic>Arabidopsis thaliana</jats:italic>. Mc1194 interacts with both the protease and granulin domains of RD21A. PLCPs are targeted by effectors secreted by bacterial, fungal and oomycete pathogens and the hypersusceptibility of<jats:italic>rd21-1</jats:italic>mutants to<jats:italic>M. chitwoodi</jats:italic>indicates RD21A plays a role in plant-parasitic nematode infection.</jats:p>
