AI Article Synopsis
- The Sanya population (SY-medaka) of Hainan medaka has a gene deletion in all males, complicating the understanding of its evolutionary background.
- Researchers resequenced the genomes of four medaka populations, identifying significant genetic differences and a bottleneck effect in the SY-medaka, which indicates a recent population decline.
- The study highlights that environmental selection strongly affects SY-medaka and identifies potential genomic regions that could explain their adaptive responses to new environmental conditions.
Article Abstract
The gene is deleted in all males of the Sanya population (SY-medaka) of the Hainan medaka, , as recently reported by us. However, due to limited knowledge regarding their population genetic background, it is difficult to explore the possible evolutionary pathway. Herein, we resequenced the whole genome of four populations, including SY-medaka. A total of 56 mitogenomes and 32,826,105 SNPs were identified. We found that the genetic differentiation is highest between SY-medaka and the other populations. The results of the population history of the suggest that the SY-medaka has been in a bottleneck period recently. Further analysis shows that SY-medaka are the most strongly affected by environmental selection. Moreover, we screened some potential genomic regions, and the genes contained in these regions may explain the potential mechanism of the selection process of the SY-medaka. In conclusion, our study can provide new clues for the adaptation process of medaka in the new environment of Sanya.
