Maize super pan-genome facilitates genetic improvement of maize

Nanhu News Network News (Correspondent Gui Songtao) Recently, the corn team of the National Key Laboratory of Crop Genetic Improvement of our school and the Hubei Hongshan Laboratory used the genome data of 721 Maize materials to construct the first Maize "super pan-genome".

Pan-genome is the sum of the genomic information of all individuals in a species, which can effectively solve the analysis bias caused by a single reference genome, and has received more and more attention in recent years

Using previously published and other publicly available data from the maize team, the study collected and integrated whole-genome sequencing data from 721 Zea spp.

Information such as gene loss during crop domestication is often difficult to accurately identify

Based on the super pan-genome, the research team also identified a large number of structural variations (SV) in the maize population, and identified a total of 274,649 structural variants in the maize population.

Finally, the research team explored the application of pan-genome in gene discovery

Background

Maize (Zea mays L.

Results

Here, we construct an approximately 6.

Conclusions

Our results highlight the underexplored role of the pan-Zea genome and structural variations to further understand domestication of maize and explore their potential utilization in crop improvement.
