Phylogenomic analyses of the East Asian endemic Abelia (Caprifoliaceae) shed insights into the temporal and spatial diversification history with widespread hybridization.

ABSTRACT:

Background and aims

Abelia (Caprifoliaceae) is a small genus with five species, including one artificial hybrid and several natural hybrids. The genus has a discontinuous distribution in Mainland China, Taiwan Island and the Ryukyu Islands, providing a model system to explore the mechanisms of species dispersal in the East Asian flora. However, the current phylogenetic relationships within Abelia remain uncertain.

Methods

We reconstructed the phylogenetic relationships within Abelia using nuclear loci generated by target enrichment and plastomes from genome skimming. Divergence time estimation, ancestral area reconstruction and ecological niche modelling (ENM) were used to examine the diversification history of Abelia.

Key results

We found extensive cytonuclear discor
