Tridge summary

A team of researchers from Hunan Agricultural University and the Oil Crop Research Institute of the Chinese Academy of Agricultural Sciences have unraveled the long-standing mysteries surrounding the origin and domestication of mustard. Publishing their findings in the prestigious journal 'Nature-Genetics', they used whole-genome sequencing and a unique local cultivar, 'Sichuan Yellow Seed', to reconstruct the mustard genome. The team's comprehensive analysis, which included research on 38 global regions and 480 mustard germplasms, revealed that mustard originated in the Middle East around 8000-14000 years ago and diversified into six distinct groups. This breakthrough not only provides crucial insights into mustard's evolution but also offers a solid foundation for utilizing mustard germplasm resources and accelerating genome selection breeding, with potential implications for enhancing mustard breeding efficiency.

New knowledge Science and Technology Daily (Reporter Yu Huiyou, Correspondent Tuo Lian Kang Lei) Mustard is one of the important economic crops in our country. It is a common oil, vegetable and condiment. Although common, the origin of mustard is still an unsolved mystery. September 7th, reporter It is learned from Hunan Agricultural University that a research result completed by the team of Professor Liu Zhongsong of the school and the team of researcher Hua Wei from the Oil Crop Research Institute of the Chinese Academy of Agricultural Sciences has effectively answered the long-standing scientific questions about the origin and domestication of mustard, and revealed the diversity and variation of mustard. The genetic basis has laid a good foundation for the utilization of mustard germplasm resources and genome selection breeding. The related results were published online in the internationally renowned journal "Nature-Genetics". The team carried out whole-genome sequencing on my ...
