中国农业科学院报道,中国农业科学院蔬菜花卉研究所研究员黄三文领导的国际番茄变异组研究团队通过对世界各地的360份番茄种质进行了重测序分析,构建了完整的番茄遗传变异组图谱,为揭示番茄的进化历史、基因挖掘和分子育种奠定了基础。最新研究成果以长篇幅论文在线发表于10月13日的Nature Genetics杂志。此前,番茄人工驯化过程一直未有全面研究。通过群体遗传学分析,该研究揭示了番茄果实变大经历了从醋栗番茄到樱桃番茄再到大果栽培番茄的两次进化过程,在此过程中分别有5个和13个果实重量基因受到了人类的定向选择。
According to the Chinese Academy of Agricultural Sciences, the research team led by Huang Sanwen, a researcher at the Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences, conducted a re-sequencing analysis of 360 tomato germplasm around the world to construct a complete map of tomato genetic variation, To reveal the evolutionary history of tomato, gene mining and molecular breeding laid the foundation. The latest research is published in a long essay online at Nature Genetics Magazine on October 13. Earlier, artificial domestication of tomato has not been fully studied. Through population genetics analysis, the study revealed that tomato fruit enlargement experienced two evolutionary processes from gooseberry tomato to cherry tomato to large-fruit cultivated tomato in which five and 13 fruit weight genes, respectively The human choice of direction.
