Successful construction of super Pan -based groups, helping the research of rice germplasm resources for rice

Integrate the pan -genes with different genetic variations in the same genus, and the constructed superpatop byk -genes can better represent the genetic variation of the entire genus.

Recently, the reporter learned from the Chinese Academy of Agricultural Sciences that the Shenzhen Institute of Agricultural Genome, the Chinese Academy of Agricultural Sciences organized research to cooperate with China Agricultural University, Nanjing Agricultural University, China Rice Research Institute, the Institute of Genetics and Development Biology of the Chinese Academy of Sciences to assemble 251 251 The high -quality rice genome has built the largest population of the most systematic, the most systematic superpatient in rice, which is the largest in the group.

It is understood that the completion of the graph will greatly promote the mining of rice functional genes and the use of rice germplasm resources. Related research results have been published online in the journal "Cell Research" online.

Rice includes two cultivation of rice cultivation rice and African cultivation rice. They are domesticated from ordinary wild rice and short tongue wild rice. The study selected 202 and highly representative 202 Asian cultivated rice core germplasm materials, with 28 ordinary wild rice, 11 African cultivation rice and 10 short tongue wild rice.

The pan -based diagram can help researchers to fully tap and use the genetic genetic mutation of rice functional genes, provide the foundation for the functional function and evolutionary research of disease resistance, and provide a reference for the complex gene families or complex chromosomal regions of the group level.

It is reported that the researchers used the constructed pan -generic sequence and corresponding group expression data to conduct correlation analysis, quickly determine the candidate gene of output -related traits, and verify the function of the candidate gene through experiments. The pan -generated diagram provides an important foundation for the research and evolutionary genome research of rice comparative genome. A comparative genome research of Asian rice and African rice reveals the genetic foundation of important agricultural traits and environmental adaptation of Asian cultivation rice and African cultivation rice.
