Other claims from this paper (7)
- Observation Pervasive ancient hybridization occurred in Caragana, particularly between sections Caragana and Calophaca.
- Association The hybridization events coincided with late Oligocene aridification.
- Association The hybridization events were temporally associated with sharp increases in diversification rates.
- Observation The LEA, SULTR and NAC gene families showed duplications and evolutionary rate shifts in hybrid lineages.
- Observation The NPF gene family showed duplications and evolutionary rate shifts in hybrid lineages.
- Observation Hybrid lineages occupy more arid habitats than either parent.
- Observation A chromosome-level genome assembly was generated for Caragana arborescens.
