Population Structure, and Comparative Genome Hybridization of European flor yeast reveal a unique family with few gene duplications.

ABSTRACT: Wine biological ageing is led in different countries in Europe: Spain, Italy, France, and Hungary, but until now no comparison of all these flor strains has been led. In this manuscript we investigated the population structure of these European flor strains from their microsatellite genotypes and analysed as well as their ploidy. We showed that almost all of these strains belong to the same cluster, and are mainly diploids. In order to detect a shared amplification pattern, we compared the hybridization profile on array of 6 flor strains from these four countries, and found only 2 genes amplified in the genome of 4 strains. Finally FLO11 polymorphism analysis revealed that most strains carry a 111 deletion in ICR1 non coding RNA, except a group of Jura Flor strains, which in contrast prese
