Genome-wide analysis of peroxidase genes in passion fruit (Passiflora edulis sims.) and their expression patterns induced by root colonization of Piriformospora indica under cold stress

Peroxidases (PODs) have various physiological and biochemical roles in plant growth, development stress response. The POD genes were identified species, but passion fruit has not yet been thoroughly characterized. Here, we discovered 30 putative from the genome of Passiflora edulis Sims. For further elucidation, comprehensive bioinformatics analysis was utilized to determine physicochemical properties, gene organization, conserved motifs, duplication phylogenetic relationships PePOD genes. Most proteins predicted be located extracellular region. Gene organization motif showed that number exons motifs each ranged vividly, between 1 19, 7 respectively. Synteny segmental played a dynamic role evolution fruit. Likewise, analysed expression patterns seedlings treated with Piriformospora indica under cold stress. relative expressions PePOD1, PePOD3, PePOD22, PePOD26 PePOD29 noticeably higher leaves P. as compared untreated ones. present study provided initial genome-wide identification characterisation Class III peroxidases laid foundation for their functional analysis.
