Chloroplast phylogenomic analysis provides insights into the evolution of the largest eukaryotic genome holder, Paris japonica (Melanthiaceae).

ABSTRACT:

Background

Robust phylogenies for species with giant genomes and closely related taxa can build evolutionary frameworks for investigating the origin and evolution of these genomic gigantisms. Paris japonica (Melanthiaceae) has the largest genome that has been confirmed in eukaryotes to date; however, its phylogenetic position remains unresolved. As a result, the evolutionary history of the genomic gigantisms in P. japonica remains poorly understood.

Results

We used next-generation sequencing to generate complete plastomes of P. japonica, P. verticillata, Trillium govanianum, Ypsilandra thibetica and Y. yunnanensis. Together with published plastomes, the infra-familial relationships in Melanthiaceae and infra-generic phylogeny in Paris were investigated, and their divergence
