Other claims from this paper (6)
- Method / resource Chromosome-scale assemblies were generated for A. zhejiangensis and A. hemsleyana.
- Observation The two A. zhejiangensis haplomes originated from A. eriantha and A. hemsleyana.
- Observation A. zhejiangensis were mainly F 1 hybrids of A. hemsleyana and A. eriantha.
- Observation Gene flow began about 0.98 million years ago.
- Observation The genomic data imply strong barriers and ongoing hybridization.
- Observation A. zhejiangensis has not initiated speciation despite recurrent hybrid origin.
