The Selaginella Genome Identifies Genetic Changes Associated with the Evolution of Vascular Plants
2011
International audience; Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported. By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Sela…
Towards a Critical Flora of Italy: Assessing the Lycopodiophyta
2013
Conspectus of Italian Selaginella (Selaginellaceae), with some typifications
2015
An annotated synonymic inventory of Italian Selaginella taxa, a practical key for their identification and their dot distribution maps are presented, as a result of our work on the Selaginellaceae account for the Flora Critica d'Italia. The names Lycopodium helveticum L. and Selaginella denticulata var. platystachya Hieron. are typified.
Diversity of Pharmacological Properties in Chinese and European Medicinal Plants: Cytotoxicity, Antiviral and Antitrypanosomal Screening of 82 Herbal…
2011
In an extensive screening, the antiviral, antitrypanosomal and anticancer properties of extracts from 82 plants used in traditional Chinese medicine and European phytomedicine were determined. Several promising plants that were highly effective against hepatitis B virus (HBV), bovine viral diarrhoea virus (BVDV)—a flavivirus used here as a surrogate in vitro model of hepatitis C virus, trypanosomes (Trypanosoma brucei brucei) and several cancer cell lines were identified. Six aqueous extracts from Celosia cristata, Ophioglossum vulgatum, Houttuynia cordata, Selaginella tamariscina, Alpinia galanga and Alpinia oxyphylla showed significant antiviral effects against BVDV without toxic effects …
Lectotypification of the spikemosses Selaginella denticulata and S. ornithopodioides (Selaginellaceae, Lycopsida)
2015
The typification of the names Selaginella denticulata (L.) Spring (≡ Lycopodium denticulatum L.) and S . ornithopodioides (L.) Spring (≡ L . ornithopodioides L.) (Selaginellaceae) is discussed. A specimen at LINN is designated as the lectotype of S . denticulata , and a specimen at BM is designated as the second-step lectotype of the name S . ornithopodioides .
