Somatic embryogenesis receptor kinases (SERKs) belong to the leucine-rich repeat receptor-like kinase (LRR-RLK) subfamily, and many LRR-RLKs have been proven play a key role in plant immune signal transmission. However, functions of SERKs resistance stripe rust caused by Puccinia striiformis f. sp. tritici remains unknown. Here, we identified gene, TaSERK1, from Xiaoyan 6, wheat cultivar possessing high-temperature seedling-plant (HTSP) fungal pathogen P. expresses its at seedling stage. The expression level TaSERK1 was upregulated upon inoculation under relatively high temperatures. transcriptional significantly increased exogenous salicylic acid brassinosteroids treatments. barley mosaic virus-induced gene silencing assay indicated that positively regulated HTSP rust. transient tobacco leaves confirmed subcellular localization on plasma membrane. Furthermore, interacted with phosphorylated chaperone protein TaDJA7, which belongs heat shock 40 subfamily. Silencing TaDJA7 compromised results when membrane perceives infection temperatures, it transmits activate pathogen.
