To elucidate the molecular mechanism of the wheat gene TaTPK, which encodes a Pti1-like tyrosine protein kinase, in resistance to stripe rust (Puccinia striiformis West f. sp. tritici), this study used a disease-resistant wheat variety Shumai 126 and a susceptible variety Taichang 29. The function of TaTPK was analyzed using techniques such as qRT-PCR, subcellular localization, virus-induced gene silencing, and histochemical observation. The results showed that after CYR34 infection, the expression level of TaTPK in the resistant variety Shumai 126 was significantly higher than in the susceptible variety Taichang 29. TaTPK encodes a membrane protein, and silencing TaTPK through gene silencing technology weakened the resistance of Shumai 126 to the stripe rust race CYR34, manifested by an increased number of spore pustules, accelerated hyphal growth, decreased H2O2 accumulation near infection sites, and a higher percentage of leaf area covered by spores. In summary, TaTPK participates in the wheat resistance response to stripe rust by regulating reactive oxygen accumulation. This study provides a candidate gene resource for durable wheat disease resistance breeding.
