Gene names and functions follow Genoscope terminology and annotations [17]. Dashes (-) represent wild-type alleles. Letters (P1, P2, SZ) represent alleles with TE insertions, discovered by genomic analyses. a. Wild-type alleles according to PCR, TE inserted alleles according to genomic sequences, may be unique to the sequenced individual of Genoscope. b. Pinot Noir allele according to both PCR and genomic sequences (P1: 6421 bp). c. Pinot noir allele according to both PCR and genomic sequences (P2: 8175 bp). d. Sangiovese and Zinfandel alleles according to PCR, not found in genomic sequences (SZ: 3246 bp)
