The genome sequence of grapevine (Vitis vinifera) reveals ancestral hexaploidization in major angiosperm phyla. The study reports a high-quality draft genome sequence of grapevine, obtained from a highly homozygous genotype, which is the fourth flowering plant genome sequence, the second for a woody species, and the first for a fruit crop. The grapevine genome has not undergone recent duplication, allowing the discovery of ancestral traits. The analysis shows that the grapevine haploid genome is derived from three ancestral genomes, a common feature in many dicotyledonous plants but not in rice, a monocotyledon. The grapevine genome sequence reveals that the three ancestral genomes contributed to the current genome. The study also shows that the grapevine genome has a higher number of gene families related to wine characteristics, such as stilbene synthases and terpene synthases, compared to other sequenced plants. The grapevine genome has a higher proportion of repetitive elements than the rice genome. The study also shows that the grapevine genome has a different distribution of genes and repetitive elements compared to rice and Arabidopsis.
