中国农业科学院棉花研究所棉花生物学国家重点实验室喻树迅研究组、华大基因研究院王俊研究组和北京大学蛋白质工程与植物基因工程国家重点实验室朱玉贤研究组等合作,完成对二倍体棉花雷蒙德氏棉基因组测序,并组装出其基因组草图。超过73%的组装序列被锚定在雷蒙德氏棉的13条染色体上。基因组包括了40976个蛋白质编码基因,其中92.2%得到了转录组学数据的证实。他们在这些数据中发现了双子叶植物共有的六倍体化事件以及棉花特有的发生在1300—2000万年前的
Institute of Cotton, Chinese Academy of Agricultural Sciences State Key Laboratory of cotton biology Yu Shuxun research group, Wang Gen Junhua Research Group and Peking University Institute of protein engineering and plant genetic engineering Zhu Yuxian Research Group and other cooperation to complete the double Genomic cotton was sequenced and the genomes were assembled. Over 73% of the assembly sequences were anchored on 13 chromosomes of Raymond cotton. The genome contains 40,976 protein-coding genes, of which 92.2% have been confirmed by transcriptomic data. They found in these data that dicotyledonous hexaploidization events and cotton-specific events that occurred between 13 and 20 million years ago
