Investigated variants, we carried out two experiments. First, we tested all the accessions for the stenospermocarpy causal mutation within the gene CDK3 drug VvAGL11 to know if it’s essential also in stenospermocarpic genetic backgrounds unique from Sultanina. Then, we searched for single nucleotide polymorphisms involving Sangiovese and Corinto Nero by exploiting the transcriptomic information created by [52]. Validated variants had been lastly tested on further clones and accessions of Sangiovese/Corinto Nero and around the other genotypes.VvAGLGenotyping with the CAPS-26.88 marker confirmed that the Sultanina accession used in this study had the point variation (G T) causing the stenospermocarpy-associated Arg197Leu substitution inside the VvAGL11 gene. All the other accessions were homozygous for the seeded allele (G/G), using the only exception of Aspirant. This accession was genotyped numerous occasions for the SNP position, corroborating the G/T genotype. Such polymorphism differentiated Aspirant from its seeded counterpart, ALDH1 manufacturer Liseiret (data not shown).Table four Cross-pollination of Trebbiano Toscano and Nebbiolo with Corinto Nero pollen.
