| Abstract;For six of the seven species of the genus Jensenia (J. pisicolor, J. connivens, J. erythropus, J. difformis, J. spinosa and J. decipiens [Pallaviciniaceae, Hepaticophytina, Bryophyta]) geomolecular divergence patterns are evaluated by comparison of the cpDNA trnTUGU-trnLUAA 5'exon intergenic spacer and trnLUAA intron and nrDNA ITS2 sequences. All studied Jensenia taxa are characterized by a low infra- and interspecific sequence variation in the investigated DNA regions. The species are differentiated by a sequence divergence of 0-2.0% (trnT-L spacer) and 0-1.3% (trnL intron and ITS2), respectively. A comparison with the molecular data of five Pallavicinia s.str. species supports the delimitation of Jensenia as a distinct taxon. (author abst.) |
