Abstract：The R gene of tomato against root-knot nematode disease is the Mi gene family，and 10
members（Mi-1 to Mi-9，Mi-HT）have been identified．Currently，the main market commodity species
of tomato rely on the resistance of Mi-1 gene，and the available resistance sources are relatively single．In this paper，based on the research progress of tomato Mi gene members and disease resistance mechanism，the signaling pathway of tomato defense against root-knot nematode invasion was analyzed and summarized．The application value and prospects of these regulatory signals in tomato breeding for resistance to root-knot nematodes were demonstrated，which provide theoretical reference for breeders to improve the ability of resistance to the root-knot nematodes disease from the aspect of signal regulation．
