Genome and Transcriptome of Sesames

The cultivated sesame S. indicum cv. XH has high sesamin content (~10 g/Kg), while S. schinzianum is a wild allotetraploid sesame with high sesamolin content (~9 g/Kg) and resistance (such as drought resistance). In this study, we presented chromosome-level genome sequences for the two sesames, respectively. We further performed compared genome and transcriptome analysis to understand the genetic and molecular feature of the two sesames. The high-quality genome assemblies and reliable analysis results contribute to the subsequent breeding research.

栽培芝麻（Sesamum indicum cv. XH）的芝麻素（sesamin）含量较高，约为10 g/Kg；而S. schinzianum为野生异源四倍体（allotetraploid）芝麻，其芝麻素林（sesamolin）含量约为9 g/Kg，且兼具抗旱等抗性。本研究分别报道了这两种芝麻的染色体级基因组（chromosome-level genome）序列。我们进一步开展了比较基因组与转录组（transcriptome）分析，以解析二者的遗传与分子特征。上述高质量基因组组装（genome assembly）结果与可靠的分析结论，可为后续育种研究提供有力支撑。
