摘要： Plants utilize different mechanisms to respond and adapt to continuously changing environmental factors. Receptor-like protein kinases (RLKs) comprise one of the largest families of plant transmembrane signaling proteins, which play critical and diverse roles in plant growth, development, and stress response. Here, we identified the necrotic dwarf (ndw) mutant introgression line (IL) 6-2, which demonstrated stunting, leaf curl, and progressive necrosis at low temperatures. Based on map-based cloning and transgenic analysis, we deter-mined that the phenotype of ndw mutant is caused by decreased expression of NDW, which encodes an RLK. NDW is a plasma membrane and cytoplasmic located protein. Overexpression of NDW can restore both of the semi-dwarf and necrotic phenotype in IL6-2 at low temperatures, further we found that NDW could significantly reduce susceptibility to Botrytis cinerea. On the contrary, knockdown NDW in M82 plants could increase the sensitivity to B. cinerea. Furthermore, transcriptional expression analysis showed that NDW affects the expression of genes related to the abscisic acid (ABA) signaling pathway. Taken together, these results indicate that NDW plays an important role in regulating plant growth, cold tolerance and mitigating susceptibility to Botrytis cinerea.
