Global plastid phylogeny of the fern family Aspleniaceae.

The family Aspleniaceae within the eupolypod II clade of leptosporangiate ferns is one of the largest fern families, including more than 700 species all over the world. They are among the most subcosmopolitan groups of ferns, but mainly distributed in the montane and (sub)tropical regions. Though two genera, Asplenium and Hymenasplenium, are generally recognized in the family, few studies have focused on the overall classification and phylogeny of Aspleniaceae. In the present project, DNA sequences of six plastid markers of ca. 1000 accessions (ca. 600 accessions are newly added) representing ca. 60% species diversity from all over the world (mainly in Southeast Asia, Pacific regions, and Americas) in the family were used to infer a phylogeny. The objective of this study is to determine major clades and the relationships among the major clades in Aspleniaceae.
