Molecular marker analysis reveals the genetic nature of color reversion in cv. ‘Moscatel Galego’ variants. a Cartoon depicting the different plant tissues and respective cell layers used for molecular analyses; b Schematic representation of MYBA1 alleles (1- VvmybA1c; 2 – VvmybA1a; 3 – VvmybA1b) and genomic location of the primer combinations used in the PCR assays [F1 + d3 – VvMYBA1(1) and c + e – VvMYBA1(2)]; c PCR assays performed on cv. ‘Pinot Blanc’ (PB), cv. ‘Pinot Gris’ (PG), cv. ‘Pinot Noir’ (PN), cv. ‘Chasselas Blanc’ (CB), cv. ‘Chasselas Roxo’ (CR), cv. Moscatel Galego Branco’ (MB) and cv. ‘Moscatel Galego Roxo’ (MR) using VvMYBA1(1) (1250 bp – VvmybA1a) and VvMYBA1(2) (198 bp – VvmybA1c and 1022 bp – VvmybA1b) primer combinations.
