摘要/Abstract

摘要： 目前可用的5个芝麻（Sesamum indicum L.）基因组草图缺乏统一的染色体编号,研究利用共线性分析确定各基因组的染色体对应关系。结果表明,豫芝11号的1号染色体与新中芝13号的1号（染色体编号,统一简写）、小黑的3号以及白芝麻和中芝13号的8号染色体对应;2号染色体与新中芝13号的2号、小黑的1号以及白芝麻和中芝13号的3号染色体对应;3号染色体与新中芝13号和小黑的4号、白芝麻的9号以及中芝13号的15、9号染色体对应;4号染色体与新中芝13号的3号、小黑的2号以及白芝麻和中芝13号的6号染色体对应;5号染色体与新中芝13号和小黑的5号以及白芝麻和中芝13号的1号染色体对应;6号染色体与新中芝13号和小黑的8号以及白芝麻和中芝13号的2号染色体对应;7号染色体与新中芝13号和小黑的6号以及白芝麻和中芝13号的10号染色体对应;8号染色体与新中芝13号的10号、小黑的9号以及白芝麻和中芝13号的5号染色体对应;9号染色体与新中芝13号和小黑的7号、白芝麻的4号以及中芝13号的4、11号染色体对应;10号染色体与新中芝13号和小黑的13号以及白芝麻和中芝13号的11号染色体对应;11号染色体与新中芝13号的11号、小黑的12号以及白芝麻和中芝13号的7号染色体对应;12号染色体与新中芝13号的12号、小黑的11号、白芝麻的13号以及中芝13号13、14、5号染色体对应;13号染色体与新中芝13号的9号、小黑的10号、白芝麻的12号以及中芝13号的12、6、16号染色体对应。实现了染色体编号统一。

Abstract: The five previously available draft genomes of sesame (Sesamum indicum L.) lacked unified chromosome numbering. This study compared the chromosome nomenclature of the genomes to avoid the confusion of using different reference genomes using genome collinearity analysis. The results showed that chromosome 1 of Yuzhi 11 corresponded to chromosome 1 of Xinzhongzhi 13 , chromosome 3 of Xiaohei, and chromosome 8 of Baizhima and Zhongzhi 13. Chromosome 2 of Yuzhi 11 corresponded to chromosome 2 of Xinzhongzhi 13, chromosome 1 of Xiaohei, and chromosome 3 of Baizhima and Zhongzhi 13. Chromosome 3 of Yuzhi 11 corresponded to chromosome 4 of Xinzhongzhi 13 and Xiaohei, chromosome 9 of Baizhima, and chromosomes 15 and 9 of Zhongzhi 13. Chromosome 4 of Yuzhi 11 corresponded to chromosome 3 of Xinzhongzhi 13, chromosome 2 of Xiaohei, and chromosome 6 of Baizhima and Zhongzhi 13. Chromosome 5 of Yuzhi 11 corresponded to chromosome 5 of Xinzhongzhi 13 and Xiaohei, and chromosome 1 of Baizhima and Zhongzhi 13. Chromosome 6 of Yuzhi 11 corresponded to chromosome 8 of Xinzhongzhi 13 and Xiaohei, and chromosome 2 of Baizhima and Zhongzhi 13. Chromosome 7 of Yuzhi 11 corresponded to chromosome 6 of Xinzhongzhi 13 and Xiaohei, and chromosome 10 of Baizhima and Zhongzhi 13. Chromosome 8 of Yuzhi 11 corresponded to chromosome 10 of Xinzhongzhi 13, chromosome 9 of Xiaohei, and chromosome 5 of Baizhima and Zhongzhi 13. Chromosome 9 of Yuzhi 11 corresponded to chromosome 7 of Xinzhongzhi 13 and Xiaohei, chromosome 4 of Baizhima, and chromosomes 4 and 11 of Zhongzhi 13. Chromosome 10 of Yuzhi 11 corresponded to chromosome 13 of Xinzhongzhi 13 and Xiaohei, and chromosome 11 of Baizhima and Zhongzhi 13. Chromosome 11 of Yuzhi 11 corresponded to chromosome 11 of Xinzhongzhi 13, chromosome 12 of Xiaohei, and chromosome 7 of Baizhima and Zhongzhi 13. Chromosome 12 of Yuzhi 11 corresponded to chromosome 12 of Xinzhongzhi 13, chromosome 11 of Xiaohei, chromosome 13 of Baizhima, and chromosomes 13, 14, and 5 of Zhongzhi 13. Chromosome 13 of Yuzhi 11 corresponded to chromosome 9 of Xinzhongzhi 13, chromosome 10 of Xiaohei, chromosome 12 of Baizhima, and chromosomes 12, 6, and 16 of Zhongzhi 13. The chromosome numbers of the five genomes were unified.
