Genomic signatures of different adaptations to environmental stimuli between wild and cultivated Vitis vinifera L.

ABSTRACT: The application of population genetic methods in combination with gene mapping strategies can help to identify genes and mutations selected during the evolution from wild plants to crops and to explore the considerable genetic variation still maintained in natural populations. We genotyped a grapevine germplasm collection of 44 wild (Vitis vinifera subsp. sylvestris) and 48 cultivated (V. vinifera subsp. sativa) accessions at 54 K single-nucleotide polymorphisms (SNPs) to perform a whole-genome comparison of the main population genetic statistics. The analysis of Wright Fixation Index (F_ST) along the whole genome allowed us to identify several putative "signatures of selection" spanning over two thousand SNPs significantly differentiated betwee
