Extensive genome-wide phylogenetic discordance is due to incomplete lineage sorting in the rapidly radiated East Asian genus Nekemias (Vitaceae).

ABSTRACT:

Background and aims

Nekemias is a small genus of the grape family, with nine species discontinuously distributed in temperate to subtropical zones of the Northern Hemisphere but mostly in East Asia. Previous phylogenetic studies on Nekemias have mainly been based on a few chloroplast markers, and the phylogenetic framework and systematic relationships are still highly contested.

Methods

We carried out a systematic framework reconstruction of Nekemias and intra-generic reticulate evolutionary analyses based on extensive single-copy nuclear and chloroplast genomic data obtained by the Hyb-Seq approach, combining genome skimming and target enrichment.

Key results

Both nuclear and chloroplast genomic data strongly support the monophyly of Nekemias with its division into t
