Data from: A phylogenetic analysis of the grape genus (Vitis L.) reveals broad reticulation and concurrent diversification during neogene and quaternary climate change

Background: Grapes are one of the most economically important fruit crops. There are about 60 species in the genus Vitis. The phylogenetic relationships among these species are of keen interest for the conservation and use of this germplasm. We selected 309 accessions from 48 Vitis species,varieties, and outgroups, examined ~11 kb (~3.4 Mb total) of aligned nuclear DNA sequences from 27 unlinked genes in a phylogenetic context, and estimated divergence times based on fossil calibrations....

Data from: Relative effects of segregation and recombination on the evolution of sex in finite diploid populations

Xiaoqian Jiang, Shaojun Hu, Qi Xu, Yujun Chang & Shiheng Tao
The mechanism of reproducing more viable offspring in response to selection is considered as a major factor influencing the advantages of sex. In diploids, sexual reproduction combines genotype by recombination and segregation. Theoretical studies of sexual reproduction have investigated the advantage of recombination in haploids. However, the potential advantage of segregation in diploids is less studied. The present study aimed to quantify the relative contribution of recombination and segregation to the evolution of sex in...
