Plastome phylogenomic analysis reveals evolutionary divergences of Polypodiales suborder Dennstaedtiineae.

ABSTRACT:

Background

Polypodiales suborder Dennstaedtiineae contain a single family Dennstaedtiaceae, eleven genera, and about 270 species, and include some groups that were previously placed in Dennstaedtiaceae, Hypolepidaceae, Monachosoraceae, and Pteridaceae. The classification and phylogenetic relationships among these eleven genera have been poorly understood. To explore the deep relationships within suborder Dennstaedtiineae and estimate the early diversification of this morphologically heterogeneous group, we analyzed complete plastomes of 57 samples representing all eleven genera of suborder Dennstaedtiineae using maximum likelihood and Bayesian inference.

Results

The phylogenetic relationships of all the lineages in the bracken fern family Dennstaedtiaceae were well resolved
