Identification of Candidate Auxin Response Factors Involved in Pomegranate Seed Coat Development.

ABSTRACT: Auxin response factors (ARFs) are transcription factors, regulating the auxin signaling pathways involved in plant development and related processes. In this study, we performed the genome-wide identification and characterization of ARFs in pomegranate and compared them with ARFs from three other species. Seventeen PgrARFs were identified and clustered into four groups, according to their phylogenetic relationship with the remaining 59 ARFs. A recent whole-genome duplication event in pomegranate may have contributed to the expansion and diversification of PgrARFs. Genomic truncation and variant splicing mechanisms contributed to the divergence of PgrARFs, a conclusion that was supported by different exon-intron structures of genes and incomplete conserved domain
