According to phylogenetic analyses of 35 nrDNA ITS1 and ITS2 sequences of Plagiochila, the two varieties of P. cucullifolia form a monophyletic lineage and are placed in a well supported clade together with five other species of Plagiochila sect.

Within Plagiochila, nrITS sequence variation is not concordant with morphological diversification. ITS sequences of Plagiochila cucullifolia s.str. and of P. dimorpha var. ecuadorica differ in only 23 aligned positions whereas two sequences of P. subplana Lindenb. differ in 86 aligned positions. Morphologically, P. cucullifolia s.str. and P. dimorpha var. ecuadorica differ in more than 20 characters and previously these two taxa were placed in separate genera.

Accordingly, gene sequences in plant mitochondria are informative for old cladogenic events, whereas intergenic regions have so far not been considered for phylogenetic reconstruction because high recombinational activity rearranges mitochondrial gene orders too frequently. Here we report that an ancient gene continuity, the nad5-nad4-nad2 gene arrangement, is conserved among the bryophyte lineages: mosses, liverworts, and hornworts. The nad4-nad2 spacer is surprisingly conserved at a size of only 26 bp in all three bryophyte lineages. In striking contrast, the small ancestral nad5-nad4 spacer, of only 57 bp in the alga Chara, is significantly increased in size, to about 600 bp in mosses and 1000-1300 bp in liverworts, and even exceeds 3000 bp in hornworts. A large group II intron fragment and a nad6 pseudogene sequence, respectively, contribute to the expanded spacer sizes in liverworts and in hornworts. The small nad4-nad2 intergenic region is retained in the lycophyte Isoetes lacustris, whereas no linkage between nad5 and nad4 could be detected in this quillwort.

In recent times, the taxon was treated both as genus Chiastocaulon Carl, as a member of Plagiochila sect. Dendroideae Gottsche, Lindenb. and Nees, and as a representative of Plagiochila subgen. Chiastocaulon (Carl) Inoue. Sequences of the chloroplast-encoded rps4 gene and the internal transcribed spacers of nuclear ribosomal DNA of 28 representatives of the Plagiochilaceae and Herbertus subdentatus (Herbertaceae, outgroup) were obtained to test the different hypotheses. Maximum likelihood analyses were performed, both on the separate and combined data sets, and in all cases resulted in a single optimal topology. The different phylogenies were congruent, but the analyses of the combined data set led to an overall more significant bootstrap support. Jungermannia dendroides was placed in a moderately supported clade with Pedinophyllum interruptum and Plagiochilion mayebarae, sister to the well supported Plogiochila clade. The topology justifies the recognition of Jungermannia dendroides as genus Chiastocaulon. Plagiochila frondescens (Nees) Lindenb., P. fruticosa Mitt. and P. pulcherrima Horik., placed alongside Chiastocaulon/Plagiochila dendroides by some authors, form a robust clade within Plagiochila (Dumort.) Dumort., assignable to P. sect. Fruticosae Inoue. The three species share the dendroid habit and alternating foliation with Chiastocaulon dendroides but lack well developed ventral intercalary branches. 11 sectional clades with robust bootstrap support were identified within the Plagiochila lineage. Many morphological characters of monophyletic lineages within the Plagiochilaceae appeared homoplastic, indicating that a natural subdivision of the family is only possible by the integration of molecular data. The molecular topologies justify a hierarchical subdivision of Plagiochila at some point in the future; however, well supported sectional groups of the molecular trees will presumably lack morphological autapomorphisms."],["dc.identifier.doi","10.1055/s-2003-44716"],["dc.identifier.isi","000188798700005"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/45049"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1438-8677"],["dc.relation.issn","1435-8603"],["dc.title","Reinstatement of Chiastocaulon carl (Plagiochilaceae), based on evidence from nuclear ribosomal ITS and chloroplast gene rps4 sequences"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
