The Arabidopsis thaliana papain-like cysteine protease RD21 interacts with a root-knot nematode effector protein
TL;DRAbstract
The root-knot nematode Meloidogyne chitwoodi secretes effector proteins into the cells of host plants to manipulate plant-derived processes in order to achieve successful parasitism. Mc1194 is a M. chitwoodi 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 Arabidopsis thaliana . 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 rd21-1 mutants to M. chitwoodi indicates RD21A plays a role in plant-parasitic nematode infection.
