Diversification and Taxonomy of the Liverwort Jubula Dumort. (Jungermanniopsida: Porellales) Inferred from Nuclear and Chloroplast DNA Sequences

摘要

Nucleotide sequence variation in the ITS1-5.8S-ITS2 region of nuclear ribosomal DNA and in the trnL-tmF region of cpDNA from 28 specimens of Jubula (Jubulaceae), and two outgroup species, was analyzed using maximum parsimony and maximum likelihood. The molecular topologies supported five to six allopatric taxa in Jubula. Relationships of most of these taxa remain unresolved due to lack of support of many deeper nodes.
