近日,中国农科院蔬菜花卉所研究员黄三文领导的研究团队,通过对世界各地的360份番茄种质进行重测序分析,构建了完整的番茄遗传变异组图谱。此研究成果揭示番茄的进化历史,并为番茄的基因挖掘和分子育种奠定了基础。据黄三文介绍,今天我们食用的栽培番茄是由野生番茄驯化而来,其果实在重量、颜色、形状等方面发生显著变化:野生番茄果实非常小,重量仅1~2克;而现代栽培番茄的果重是其祖先的100多倍。通过群体遗传学
Recently, the research team led by Huang Sanwen, a researcher at the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences, constructed a complete map of the genetic variation of tomato genomes by re-sequencing 360 tomato germplasm around the world. The research results reveal the evolutionary history of tomato and lay the foundation for gene discovery and molecular breeding of tomato. According to Huang Sanwen, the cultivated tomatoes we consume today are domesticated by wild tomatoes, and their fruits vary significantly in weight, color, shape, etc. Wild tomato fruits are very small and weigh only 1-2 grams; whereas modern cultivated tomatoes The fruit weight is 100 times more than its ancestors.
