The pathogenesis-related protein PR10 plays a vital role in plant growth, development, and stress responses. This study systematically identified and analyzed PR10genes in cultivated peanut (ArachishypogaeaL.), examining their phylogenetic relationships, conserved motifs, gene structures, and syntenic relationships. The analysis identified 54 AhPR10genes, which were classified into eight groups based on phylogenetic relationships, supported by gene structure and conserved motif characterization. Analysis of chromosomal distribution and synteny demonstrated that segmental duplications played a crucial role in the expansion of the AhPR10gene family. The identified AhPR10genes exhibited both constitutive and inducible expression patterns. Significantly, AhPR10-7, AhPR10-33, and AhPR10-41demonstrated potential importance in peanut resistance to Aspergillus flavus. Invitrofungistatic experiments demonstrated that recombinant AhPR10-33 effectively inhibited A.flavusmycelial growth. These findings provide valuable insights for future investigations into AhPR10 functions in protecting peanut from A.flavusinfection.
