The putative ABCG transporter VviABCG20 from grapevine (Vitis vinifera) is strongly expressed in the seed coat of developing seeds and may participate in suberin biosynthesis.

ABSTRACT: Half-size ATP binding cassette G (ABCG) transporters participate in many biological processes by transporting specific substrates. Our previous study showed that VviABCG20 was strongly expressed in the seeds of seeded grape and the silencing of VviABCG20 homolog gene in tomato led to a reduction in seed number. To reveal the molecular mechanism of VviABCG20 gene involved in grape seed development/abortion, the gene expression and functional analysis of VviABCG20 were further carried out in the grapevine. It was shown that the gene expression of VviABCG20 was higher in seeds of seeded grapes compared with seedless. Further the expression of VviABCG20 in the seed coat was significantly higher than in ovules (young seeds) and endosperm. VviABCG20</
