Genome-wide identification and functional analysis of class III peroxidases in Gossypium hirsutum.

ABSTRACT: Class III peroxidase (PRX) genes play essential roles in various processes, such as auxin catabolism, removal of H₂O₂, crosslinking cell wall components, and response to biotic and abiotic stresses. In this study, we identified 166, 78 and 89 PRX genes from G. hirsutum, G. arboretum and G. raimondii, respectively. These PRX genes were classified into seven subfamilies based on phylogenetic tree analysis and the classification of PRX genes in Arabidopsis. Segmental duplication and purifying selection were the major factors driving the evolution of GhPRXs. GO and KEGG enrichment analysis revealed that GhPRX genes were mainly associated with responding to oxidative stresses, peroxidase activitie
