Abstract: PR10 is a kind of pathogenesis-related protein (Pathogenesis related proteins, PRs), which was induced by various biotic and abiotic stress. This paper reviewed and summarized the recent progress of PRs and PR10 firstly. PR10 protein sequence and structural characteristics were mainly introduced and PR10 signal transduction pathways were summarized combining with domestic and foreign research production; Different functions of PR10 protein were analyzed, such as having nuclease activity, resistance to pathogenic microorganisms and other biotic and abiotic stress, as well as being closely related to the host cell programmed death. Finally, still existing problems in the present study and future prospects were put forward for PR10. So we think deep exploring on the function and mechanism of this disease resistance-related gene for improving the quality and yields of crops has important significance in the future.
