基于高通量测序的福安刺葡萄基因组初步研究

A Preliminary Report on Genomics of Vitis davidii Foëx from Fuan District UsingHigh-throughput Genome Sequencing Method

  • 摘要: 为进一步了解福建福安刺葡萄的遗传背景,寻找刺葡萄与欧亚种葡萄之间的遗传差异,本研究基于高通量测序技术展开对福安刺葡萄基因组的分析,共得到测序数据8.4 Gb,鉴定出3 192 484处非冗余遗传差异。差异位点分布位置结果显示,30.34%的差异位于基因间区,3.67%的差异位于基因外显子区。通过对比葡萄参考基因组序列,共鉴定出刺葡萄基因组上存在1 863 237个同源SNP、1 244 590个异源SNP位点,表明本次测序所用的福安刺葡萄有可能是异源二倍体。

     

    Abstract: Genetic variants in Vitis davidii from Fuan District in Fujian were studied using the high-throughput genome sequencing method. The 8.4 Gb of raw data were analyzed to result in the identification of 3 192 484 non-redundant genetic variants. Distribution of the variants showed 30.34% in the intergenic regionand 3.67% in the exon region. By comparing the genome sequences of the V. davidii under study with those of the entire grape references, 1 863 237 homo-type SNP and 1 244 590 hetero-type SNP were found. It appeared that the V. davidii from Fuan were most likely to be allodiploidy. The study also indicated that using genetic sequencing to determine the genome-wide variants of V. davidii was a viable tool for better understanding of the genetic background of the plant in question.
