| 英文摘要 | Sugar content is a key feature of grape quality. The sugar content of grapes has been significantly improved after nearly a thousand years of artificial selection. However, the mechanism underlying the changes in the grape sugar content during the process of artificial selection remains largely unknown although several genes involved in sugar metabolism and transportation in grape have been identified. In this study, the genomes of 13 wild Vitis species and 14 cultivated Vitis vinifera accessions were resequenced to 2-5 X depth using the Illumina Hiseq2000 platform. Genetic variation of 138 genes involved in sugar biosynthesis and transport was investigated, and 7,690 and 12,717 single nucleotide polymorphisms/insertions and deletions (SNPs/InDel) were identified within the cultivated V. vinifera and wild Vitis species, respectively. The percentages of SNPs/InDels were 0.93 and 1.54 % in cultivated and wild species, respectively, and the wild Vitis species had 1.65-fold more SNPs/InDels than the cultivated V. vinifera. Moreover, the distribution of SNPs/InDels in gene regions was also investigated. Eight genes (HT4, PPFTK4, PPFTK6, PMT3, SPS1, HT8, HT15, SUSy1) showed low level of allelic diversity in cultivated species, suggesting they might have undergone purifying selection during the domestication process of grapes. Our genome DNA resequencing data provided a valuable resource for analyzing the effects of artificial selection on trait-related pathways in grape. The result that eight genes showed lower level of DNA variation in cultivated species than in wild species will be very helpful in understanding sugar accumulation in grapes. |
