植物de novo基因组数据（2019）

为了解析蔓菁如何、何时进入青藏高原，探讨蔓菁在青藏高原传播与驯化与早期人类活动的高原定居和古丝绸交流之间的关系，2018年6月，课题组利用三代基因组测序技术，对青海省囊谦县的蔓菁自交F1代品种进行全基因组测序和De Novo组装，得到组装基因组大小为409.69 Mb，Contig N50为1.21 Mb。这一结果可为研究植物扩散与人类活动之间的关系提供遗传基础。同时，这项研究有助于揭示人工驯化和人类选择对蔓菁的遗传分化的影响，以及蔓菁适应高原生态环境的适应性机制。

To clarify how and when turnip entered the Qinghai-Tibet Plateau, and investigate the correlation between the spread and domestication of turnip on the Qinghai-Tibet Plateau and two core aspects of early human activities: highland settlement and ancient Silk Road exchanges, the research team conducted whole-genome sequencing and de novo assembly on the inbred F1 variety of turnip collected from Nangqên County, Qinghai Province using third-generation genome sequencing technology in June 2018. The assembled genome has a size of 409.69 Mb, with a Contig N50 of 1.21 Mb. These findings provide a genetic foundation for research into the relationship between plant dispersal and human activities. Meanwhile, this study aids in uncovering the impacts of artificial domestication and human selection on the genetic differentiation of turnip, as well as the adaptive mechanisms that allow turnip to thrive in the highland ecological environment.
