Phylogenetic relationships in lycophyte genus Selaginella based on the 18S-5.8S-26S rDNA.

The largest lycophyte genus Selaginella (Selaginellaceae) contains ca. 800 species. It has cosmopolitan distribution but its highest species diversity is apparently found in tropical and subtropical regions. Although phylogenetic relationships and infrageneric classification of Selaginella are now relatively well established, these results are mainly based on plastid data and there are unresolved issues not addressed by plastid data. In this study phylogenetic relationships of Selaginella are explored based on nuclear 18S-5.8S-26S rDNA genes (> 2800 bp) with the goals: (1) to test the phylogenetic hypotheses based on plastid data; and (2) to gain new insights into the evolution of diagnostic morphological characters in some subgenera/sections of the genus.
