摘要： Multiple transmembrane proteins perform functions such as immune stress and signal transduction, and we cloned and characterized an immune-functional, transmembrane protein MiRPH1, from mango. Expression analysis showed that MiRPH1 has tissue-specific characteristics and is induced by pathogens and phytohormones. Under pathogenic infection, overexpression of MiRPH1 could increase the accumulation of salicylic acid (SA), catalase (CAT), and peroxidase (POD) in plants, reduces the biomass of pathogenic fungus, and upregulates the expression of multiple defense-related genes, thereby enhancing plant disease resistance. It is speculated that MiRPH1, as a transmembrane protein that exercises immune function, can enhance the resistance of mangoes to pathogenic fungus.
