The tandem repeat mutation in the promoter region of VvmybA1 specific for teinturier varieties. (A) PCR result of the white (MybA1a), red (MybA1c) and teinturier alleles (MybA1t2, MybA1t3 and MybA1t5) of DNA prepared from leaves (L1 + L2) and roots (L2) of three different ‘Teinturier’ clones. ‘Pinot Noir’ as reference. (B) Schematic diagram of the three teinturier alleles found (MybA1t2, MybA1t3 and MybA1t5) named based on the repeat number of the 408 bp GCE element (grapevine color enhancer) in the promoter region of VvmybA1. Red and white alleles as reference.
