Overview of molecular features supporting the proposed speciation within the Physcomitrium-Physcomitrella species complex. The re-classified species (subspecies following the former classification of Tan 1979 in brackets) are arranged as supported by data presented in this study, modified after [12]. Dashed lines indicate hybridization events resulting in the three species of Physcomitrium. The dotted line illustrates the clustering of A. serratum together with P. patens. The requirement of editing at particular positions in nad3 and nad4 is shown. The RNA editing site nomenclature consists of affected gene, position in the reading frame and the resulting amino acid codon change induced by RNA editing [32]. C (Cytidine) at the DNA level indicates an editing site, whereas no editing is required in the case of a thymidine (T) at the appropriate position. The number of BRK1 loci (homeologs) is depicted for all analyzed species, while *indicates SSR-based support for the three Physcomitrella species.
