摘      要：Salt stress is a major abiotic stress which severely hinders crop ***,the regulatory network controlling tomato resistance to salt remains ***,we found that the tomato WRKY transcription factor WRKY57 acted as a negative regulator in salt stress response by directly attenuating the transcription of salt-responsive genes(Sl RD29B and Sl DREB2)and an ion homeostasis gene(Sl SOS1).We further identified two VQ-motif containing proteins Sl VQ16 and Sl VQ21as Sl WRKY57-interacting *** VQ16 positively,while Sl VQ21 negatively modulated tomato resistance to salt *** VQ16 and Sl VQ21 competitively interacted with Sl WRKY57 and antagonistically regulated the transcriptional repression activity of Sl ***,the Sl WRKY57-Sl VQ21/Sl VQ16 module was involved in the pathway of phytohormone jasmonates(JAs)by interacting with JA repressors JA-ZIM domain(JAZ)*** results provide new insights into how the Sl WRKY57-Sl VQ21/Sl VQ16 module finely tunes tomato salt tolerance.
