Identification and analysis of VTC2 homologs encoding key enzyme of L-ascorbic acid biosynthesis in tomato species (Solanum section of Lycopersicon)

The complete nucleotide sequences of 11 wild and cultivated tomato GDP-L-galactose-phosphorylase-1 homologs (VTC2) were identified and characterized. The overall level of nucleotide variability was 9.19%. Totally 25 out of 54 cDNA SNPs, were non-synonymous and resulted in amino acid substitutions. In the group of green-fruited tomato species, more SNPs were detected than in the group of red-fruited species, but the percentage of non-synonymous substitutions in red-fruited tomatoes was significantly higher (66.7% vs. 37.5%). In the translated amino acid sequences the GDF-L-galactose-hexose-1-phosphate guanyltransferase domain and highly conserved HIT-motif were identified and a conservative motif specific for VTC2 of Solanoideae species was detected.
