Résumé
Black-skinned and red-fleshed grape 'Brazil' is a bud sport of rosy-skinned 'Benitaka'. 'Brazil' has a much higher anthocyanin content in the skin than that of 'Benitaka' and is characterized by the accumulation of anthocyanins in the flesh. Our genomic analysis of the VvMYBA loci, which regulate anthocyanin biosynthesis, suggested that the difference in skin and flesh color between 'Brazil' and 'Benitaka' cannot be explained by genomic alteration at the loci. Expression levels of VvMYBA1 and anthocyanin biosynthesis-related genes in skin and flesh were significantly higher in 'Brazil' than in 'Benitaka' throughout berry development. DNA methylation levels in the 3' long terminal repeat (LTR) of a retrotransposon in the upstream region of VvMYBA1
