Fern phylogeny inferred from 400 leptosporangiate species and three plastid genes
Abstract
In an effort to obtain a solid and balanced approximation of global fern phylogeny
to serve as a tool for addressing large-scale evolutionary questions, we assembled
and analyzed the most inclusive molecular dataset for leptosporangiate ferns to date.
Three plastid genes (rbcL, atpB, atpA), totaling more than 4,000 bp, were sequenced
for each of 400 leptosporangiate fern species (selected using a proportional sampling
approach) and five outgroups. Maximum likelihood analysis of these data yielded an
especially robust phylogeny: 80% of the nodes were supported by a maximum likelihood
bootstrap percentage ≥ 70. The scope of our analysis provides unprecedented insight
into overall fern relationships, not only delivering additional support for the deepest
leptosporangiate divergences, but also uncovering the composition of more recently
emerging clades and their relationships to one another.
