Genome-wide identification of glutathione peroxidase (GPX) gene family and their response to abiotic stress in cucumber.

ABSTRACT: Plant glutathione peroxidases (GPXs) are non-heme thiol peroxidases that play vital roles in maintaining H₂O₂ homeostasis and regulating plant response to abiotic stress. Here, we performed a comparative genomic analysis of the GPX gene family in cucumber (Cucumis sativus). As a result, a total of 6 CsGPX genes were identified, which were unevenly located in four out of the seven chromosomes in cucumber genome. Based on the phylogenetic analysis, the GPX genes of cucumber, Arabidopsis and rice could be classified into five groups. Analysis of the distribution of conserved domains of GPX proteins showed that all these proteins contain three highly conserved motifs, as well as other conserved sequences and residues.
