Title

A high-quality Buxus austro-yunnanensis (Buxales) genome provides new insights into karyotype evolution in early eudicots

Zhenyue Wang; Ying Li; Pengchuan Sun; et al. BMC Biology 2022. doi:10.1186/s12915-022-01420-1

Other claims from this paper (12)

Observation Buxales and Trochodendrales were classified as sister lineages.
Observation Buxales and Trochodendrales were placed as sisters to core eudicots.
Observation Ranunculales was the first lineage to diverge from these groups.
Mechanism Incomplete lineage sorting and hybridization were identified as main contributors to 34.33% phylogenetic discordance.
Observation B. austro-yunnanensis underwent one whole-genome duplication event.
Observation Collinear gene phylogenies suggested independent polyploidizations in five eudicot lineages.
Method / resource The ancestral eudicot karyotype was reconstructed.
Method / resource Nearly gapless karyotype projections were generated for each eudicot species.
Observation A common chromosome fusion event was recovered in asterids.
Observation A common chromosome fusion event was recovered in malvids.
Observation Aquilegia and Vitis fused ancestral karyotypes at different positions.
Mechanism Different fusion positions imply different karyotype evolution histories for Aquilegia and Vitis.
