Deep sequencing of Ptilidium (Ptilidiaceae) suggests evolutionary stasis in liv...
Forrest, L. L.; Wickett, N. J.; Cox, C. J.; Goffinet, B.Background and aims – Organellar genome sampling is patchy for non-vascular groups, with the earliest land plants poorly represented; currently only two liverworts, two mosses and one hornwort have sequenced, annotated plastid genomes. This is in part due to methodological difficulties that have hampered attempts to generate plastid genome data from liverworts. In this paper we present a method that overcomes s...
Global patterns of moss diversity: taxonomic and molecular inferences
Shaw, A. J.; Cox, C. J.; Goffinet, B.Taxonomic and molecular data were utilized to test the hypothesis that moss diversity is greatest near the equator. Species richness estimates from 86 taxonomic checklists representing global moss diversity do not support the hypothesis that, in general, mosses are more species-rich in the tropics than at higher latitudes.
Phylogenetic significance of the rpoA loss in the chloroplast genome of mosses
Goffinet, B.; Wickett, N. J.; Shaw, A. J.; Cox, C. J.A recent survey of arthrodontous mosses revealed that their chloroplast genome lacks the gene encoding the alpha subunit of the RNA polymerase (i.e., rpoA), and that at least in Physcomitrella patens the gene has been transferred to the nuclear genome. Subsequently the gene was recorded from the cytoplasmic genome in Takakia and Sphagnum. Here we extend the survey to representatives of all major lineages of mos...
