Genome-Wide Identification and Evolutionary Analysis of AOMT Gene Family in Pomegranate (Punica granatum)

Gene duplication is the major resource with which to generate new genes, provide raw material for novel functions evolution. Thus, elucidate gene family evolution after events of vital importance. Anthocyanin O-methyltransferases (AOMTs) have been recognized as being capable anthocyanin methylation, increases diversity and stability improves protection plants from environmental stress. Meanwhile, no detailed identification or genome-wide analysis AOMT members in pomegranate (Punicagranatum) reported. Three published genome sequences offer substantial resources explore based on whole genome. Altogether, 58 identified OMTs five other species were divided into group OMT group, according their phylogenetic tree AOMTs derived OMTs. same subclade a similar structure protein conserved motifs. The PgAOMT evolved expanded primarily via whole-genome (WGD) tandem duplication. PgAOMTs expression pattern peel aril development by qRT-PCR verification indicated that had tissue-specific patterns. main fates neo- non-functionalization events. High genes PgOMT04 PgOMT09 speculated contribute “Taishanhong” pomegranate’s bright red color. Finally, we integrated above order infer evolutionary scenario family.
