Data on Bryology Reported by Researchers at Missouri Botanical Garden [Phylogenetic position of the genus Bryhnia Kaurin (Brachytheciaceae, Bryophyta) inferred from chloroplast (rpl16, trnG, trnL-F) and nuclear (ITS) sequence data]

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Life Science Research are discussed in a new report. According to news reporting originating in St. Louis, Missouri, by NewsRx journalists, research stated, "The systematic position of the genus Bryhnia Kaurin has been problematic and remains unsettled. A phylogenetic analysis of Bryhnia and closely related genera, based on the nuclear marker ITS1-5.8S-ITS2 and the plastid markers rpl16, trnG, and trnL-F, was carried out to clarify their relationships and systematic positions."

The news reporters obtained a quote from the research from Missouri Botanical Garden, "The phylogenetic trees generated from Maximum parsimony and Bayesian analyses show that Bryhnia s.s., represented by B. novae-angliae (Sull. & Lesq.) Grout, B. hultenii E. B. Bartram, and B. scabrida (Lindb.) Kaurin, forms a maximally supported clade nested within Brachythecium Schimp. 'Bryhnia scabrida' sensu Ignatov & Huttunen (2002) is Bryhnia brachycladula Cardot, and together they form a monophyletic group with Eurhynchiadelphus eustegia (Besch.) Ignatov & Huttunen and Myuroclada maximowiczii (G. G. Borshch.) Steere & W. B. Schofield. We propose the inclusion of the species currently recognized in Bryhnia in Brachythecium, with the transfer of Bryhnia brachycladula to the genus Myuroclada Besch."

According to the news reporters, the research concluded: "Bryhnia brachycladula is further treated as a synonym of the new combination, Myuroclada longiramea (Mull. Hal.) M. Li, Y.F. Wang, M. S. Ignatov & S. Huttunen."
