Genome-Wide Identification of ATP-Binding Cassette (ABC) Transporter Provides Insight to Genes Related to Anthocyanin Transportation in New Teinturier Grape Germplasm ‘ZhongShan-HongYu’

ATP-binding cassette (ABC) transporters are a large class of superfamily involved in variety biological processes with multiple functions, including phytohormone transport, heavy metal ion detoxification, and so on. Anthocyanin pigmentation grapes is commercially important feature this superfamily. To elucidate the mechanisms VvABC gene at different stages grape berries, we analyzed characterized ABC family ‘ZhongShan-HongYu’ (ZS-HY) berries using RNA-seq analysis. In study, total 146 genes were identified by comprehensive bioinformatics analysis, which outlined their structure, chromosomal location, conserved domains, phylogenetic relationships, collinearity The could be divided into eight subfamilies based on Fifty-eight from data, 31 belong to ABCG subfamily, 15 ABCC 8 ABCB 2 ABCF only 1 belongs each ABCA ABCD subfamilies. We used qRT-PCR detect expression organs found that it changed significantly organs. Phylogenetic analysis showed anthocyanin transport other species closely related members subfamily. Subsequently, promoter elements protein interactions VvABCC was performed. This study has improved our understanding functions provided basis for role transport.
