The study of VvMybA1 allele status of the indigenous grapevine varieties with non-colored berries

Abstract

In the present work we describe preliminary results on a partial VvMybA1 locus sequencing of rear indigenous grapevine varieties. Obtained sequences were mostly conservative and have matches in NCBI GenBank. As expected, most of them have a sequence that is typical for varieties with non-colored berries. Surprisingly, however, cultivar Jaj izium biely demonstrated structure typical for varieties with colored berries, which implies another reason for the loss of color. Obviously, Tavlinskii pozdnii and Sypun chernyj varieties had typical for colored cultivars allele structure. Some nucleotide substitutions and differences in structure of sequences were found. Furthemore, we submitted our sequences to the NCBI and here we present their accession numbers: Unji bely (MW633123), Voskeat (MW633125), Tsolikauri (MW633126), Shabash (MW633127), Terbash (MW633130), Bajan Shirei (MW633131), Katta Kurgan (MW633132), Sirgula (MW633135), Khatmi (MW633136), Jaj izium biely (N/A), Tavlinskii pozdnii (MW633139), Sypun chernyj (MW633151). All sequences, excluding Jaj izium biely genotype, were submitted to the GenBank and will be available to the public as soon as possible.
