Chinese scientistsSuccessful measurement and analysisThe whole genome sequence of wheat is about 3800 years ago. The study was published in the journal《The Plant Journal》 In periodicals. Hexaploid wheat is one of the most important food crops in the world. The domestication of common wheat began about 10,000 years ago in the crescent fertile land of the Near East, then spread westward to Europe and eastward to East Asia. However, the transmission route of wheat into China is still unclear.
Chinese researchers extracted genomic DNA from a single wheat seed 3,800 years ago and used a new generation of sequencing technology to complete genome sequencing and sequence assembly of seven ancient wheat seeds unearthed from graveyards in Xiaohe and Gutomugou, Xinjiang. Genome data analysis and morphological observation have proved that the unearthed wheat is hexaploid common wheat. The ancient wheat is closely related to the existing common wheat landraces in southwestern China.
This study proposed the diffusion route of common wheat from the edge of the Qinghai-Tibet Plateau to the Yangtze River Basin, which provided direct evidence for understanding the cultural exchanges between the East and the West and agricultural communication.
