摘要： Pathogenesis-related protein-1 (PR1) encodes a water-soluble protein produced in plants after pathogen infection or abiotic stimulation. It plays a crucial role in plant-induced resistance by attacking pathogens, degrading cell wall macromolecules and pathogen toxins, and inhibiting the binding of viral coat proteins to plant receptor molecules. Compared to model plants, the mechanism of action of PR1 in wheat remains underexplored. In this study, the recently published wheat genome database (IWGSC RefSeq V2.1) was used to identify 83 genes in the TaPR1 gene family. Compared to previous work, the duplicate genes were removed and we corrected misannotated genes. Fourteen TaPR1 genes involved in the wheat-Pst interaction were identified based on RNA sequencing from Xinchun 32. The expression patterns of eight genes were validated using qRT-PCR, and the results showed that PR1 was highly expressed following Puccinia striiformis f. sp. tritici (Pst) infection. This study enhances previous research on wheat PR1, contributing to a more comprehensive understanding of the TaPR1 gene family and providing a reference for the screening of more broad-spectrum and high-resistance wheat populations.
