Genosystematics and new insight into the phylogeny and taxonomy of liverworts

The current state of molecular studies in liverworts, including original data, was considered. The traditional concepts of the liverwort phylogeny and systematics have greatly changed as a result of recent molecular researches. The phylogenetic inferences from studies of different DNA loci of different species sampling are mainly congruent. The phylogeny and systematics of the suborder Jungermaniineae, one of the largest and taxonomically difficult groups, is discussed on the basis of nucleotide sequence analyses of internal transcribed spacers 1 and 2 (ITS1-2) of nuclear rDNA and chloroplast trnL-F in a representative species sampling.
