我国科学家获得首个染色体级别橡胶树参考基因组图谱

 本网讯(记者 焦宏)由云南省热带作物科学研究所特聘研究员、中国科学院昆明植物研究所研究员、热带作物种质资源与基因组学云南省创新团队首席科学家高立志教授带领的云南省热带作物科学研究所、中国科学院昆明植物研究所和华南农业大学基因组学与生物信息学研究中心的联合研究团队,历经 6 年,与华大基因、美国华盛顿大学、哈佛大学等单位合作,在完成了二代基因组测序与组装的基础上,进一步克服了橡胶树基因组庞大、高杂合与高重复等困难,利用单分子实时测序(SMRT)和 Hi-C 技术,在国际上首次获得了达到染色体级别的高质量巴西橡胶树优良品种 GT1的参考基因组序列,并揭示大戟植物基因组的染色体进化、胶乳生物合成与橡胶树的驯化。该成果以 “The Chromosome-based Rubber Tree Genome Provides New Insights into Spurge Genome Evolution and Rubber Biosynthesis ” 为题发表在国际植物学顶尖刊物 Molecular Plant。
