Reconstructing the evolutionary trajectory of Chamaelirium (Melanthiaceae) through phylogenomics: insights from plastome dynamics and historical biogeography.

ABSTRACT:

Background

The East Asia-eastern North America disjunction represents a classic biogeographic pattern, widely interpreted as a relic of Tertiary temperate forests that were widespread across the Northern Hemisphere. Although this pattern has been well-documented in woody plants, disjunctions in herbaceous taxa have remained relatively unexplored, despite their potential to provide significant evolutionary insights. The genus Chamaelirium represents a suitable system for investigating herbaceous discontinuity between East Asia and eastern North America. However, unresolved section-level relationships within the genus based on limited molecular data indicated that its systematics still required clarification. Here, we generated complete plastid genomes (plastomes) for five Chamaeliri
