Perennial ryegrass (Lolium perenne L.) displays a two-locus gametophytic self-incompatibility (SI) system that remains intact at the tetraploid level. Two models are plausible for SI in autotetraploids. In Model I: both alleles at the S locus and both at the Z locus in diploid pollen matching the female genotype results in incompatibility. In Model II: only one allele at S and one at Z locus in diploid pollen matching the female results in incompatibility. The goals were to determine which of the models best explains SI in our autotetraploid ryegrass population and to evaluate the efficiency of high-resolution melting (HRM) genotyping for discriminating different iso-allelic genotypes. The progeny of a cross between two autotetraploids was characterized with three HRM-based markers co-segregating with Z. Segregation ratios were used to make inferences about the mode of action of the SI system. The observed segregation differed significantly (P < 0.001) from the expected under Model I, but not from the expected under Model II (P = 0.463). Thus, Model II explains SI in this population, and HRM is an efficient tool to distinguish different isoallelic genotypic classes. |

ABSTRACT - Although the ancient Vitis vinifera Tannat variety is virtually unknown in the international wine market, the strategy to promote it as the Uruguayan emblematic grape variety is starting to become successful in the red wines market. This paper presents a summary of the latest research and developments performed in
Uruguay with Tannat since the late 1970s, its origin and production statistics. As an expression of the state-of-the-art viticultural technology developed in Uruguay for this variety during the last ten years, the chemical characterization of the polyphenolic and aroma profiles, typical for this variety, is also presented. The high
polyphenolic content of this V. vinifera variety, when compared to other red grapes, confer its wines a high free radicals scavenging activity. Furthermore, from the
winemaking point of view, some New World wine-producing countries have planted this grape to blend it with their own varieties, with the purpose of adding more
structure and aging potential to their premium red wines. |
