SlVQ15 recruits SlWRKY30IIc to link with jasmonate pathway in regulating tomato defence against root-knot nematodes.

ABSTRACT: Tomato is one of the most economically important vegetable crops in the world and has been seriously affected by the devastating agricultural pest root-knot nematodes (RKNs). Current understanding of tomato resistance to RKNs is quite limited. VQ motif-containing family proteins are plant-specific regulators; however, whether and how tomato VQs regulate resistance to RKNs is unknown. Here, we found that SlVQ15 recruited SlWRKY30IIc to coordinately control tomato defence against the RKN Meloidogyne incognita without affecting plant growth and productivity. The jasmonate (JA)-ZIM domain (JAZ) repressors of the phytohormone JAs signalling associated and interfered with the interaction of SlVQ15 and SlWRKY30IIc. In turn, SlWRKY30IIc bound to SlJAZs promoters and cooperated with SlVQ15 to repre
