Abstract

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.
