Phylotranscriptomics of liverworts: revisiting the backbone phylogeny and ancestral gene duplications.

ABSTRACT:

Background and aims

With some 7300 extant species, liverworts (Marchantiophyta) represent one of the major land plant lineages. The backbone relationships, such as the phylogenetic position of Ptilidiales, and the occurrence and timing of whole-genome duplications, are still contentious.

Methods

Based on analyses of the newly generated transcriptome data for 38 liverworts and complemented with those publicly available, we reconstructed the evolutionary history of liverworts and inferred gene duplication events along the 55 taxon liverwort species tree.

Key results

Our phylogenomic study provided an ordinal-level liverwort nuclear phylogeny and identified extensive gene tree conflicts and cyto-nuclear incongruences. Gene duplication analyses based on integrated phyloge
