Plant Pathogenesis-Related Protein PR10 and Their Research Progress in Peanut
[Objective]The research progress on plant PR10 genes were reviewed to lay a foundation for the analysis of the molecular mechanism of plant resistance to stress and the mining of stress resistance genes.[Method]By consulting related literatures,the basic structure,biological functions and signal transduction pathways in response to adverse stresses of the plant PR10 protein family were summarized and commented.[Result]PR10 proteins exist widely in the genome of higher plants.It is a kind of intra-cellular proteins without signal peptides and has nuclease activity which is closely related to its highly conserved"P-loop"(GXGGXG)motif.PR10s,with constitutive and inducible expression patterns,play an important role in plant resistance to stress.However,the clear regulatory mechanism remains to be fur-ther dissected,and the research progress of PR10s in peanut is relatively backward.[Conclusion]The cloning and analysis of regulation mechanism of PR10 genes associated with stress resistance in peanut need to be strengthened.Further mining of excellent allelic variation can provide genetic resources for the cultivation of new peanut varieties with stress tolerance.
