Cytogenetic, geographical, spore type and plastid haplotype data reveal cryptic patterns of species diversity in the cosmopolitan Cystopteris fragilis complex (Polypodiopsida: Cystopteridaceae) / Libor Ekrt in Botanical Journal of the Linnean Society, vol. 199, n°3 (Année 2022)

Rothfels, Auteur ; Kristýna Hanušová (Hanusova), Auteur ; Ondřej Hornych, Auteur ; Tomas Urfus, Auteur Année de publication : 2022 Article en page(s) : pp. 728-739 Langues : Anglais Catégories : [Espèces (in biblio)] Cystopteris dickieana [Espèces (in biblio)] Cystopteris fragilis [Thèmes] Ptéridophytes (fougère, prêle, lycopode, isoète, sélaginelle) [Thèmes] Taxonomie Mots-clés : cytogénétique, cytotaxonomie  hybridation  polyploïdie  Spore  ADN chloroplastique  phylogénétique Résumé : "The delimitation of lineages in the Cystopteris fragilis complex is complicated by the presence of multiple cytotypes and a lack of defining morphological characters. One character, the production of rugose instead of regular spiny spores, is sometimes associated with a potential Scottish endemic, C. dickieana; however, whether this character is associated with a distinct lineage is uncertain. To better understand the diversity in the C. fragilis complex, we selected 87 C. fragilis samples of known ploidy (4x, 5x, 6x) for sequencing of two plastid loci and we assessed their spore types. These samples represent the variability found in Northern Hemisphere populations, including the type locality of C. dickieana in Scotland. Our analyses revealed two haplotype lineages, which we label the hemifragilis and reevesiana clades, based on their potential relationship to the two presumed diploid parents of C. fragilis. Hexaploids and tetraploids were both polyphyletic. Rugose spores were rarer overall (26% of samples), but five times more prevalent in the hemifragilis clade. Although proper delimitation and understanding of C. fragilis remains a challenge, this study further describes great genotypic and cytotypic complexity present in this complex. Furthermore, rugose-spored plants are widely distributed and should not be associated with a single name."

How many orchid species are currently native to the British Isles ? / Richard M. Bateman

Public in Current taxonomic research on the British & European Flora (Leicester, 13-14 September 2003) / John Bailey (2006) Titre : How many orchid species are currently native to the British Isles ? Type de document : Livre Auteurs : Richard M. Bateman, Auteur Importance : pp. 89-110 Langues : Anglais Catégories : [Espèces (in biblio)] Orchidaceae [ZG] Europe [Thèmes] Génétique Mots-clés : classification  DNA  phylogénétique  population génétique Résumé : "The British Isles probably host the most intensively studied flora in the world, and within that flora the Orchidaceae has long been the most intensively studied family. Nonetheless, molecular phylogenetic studies performed only during the last decade have revolutionised our understanding of species relationships among European orchids, eliminating former monotypic genera such as Aceras, Coe/oglossum and Hammarbya, apportioning many former Orchis species to expanded concepts of Anacamptis and Neotinea, and combining 'Listera' into Neottia. Emphasis has now switched from species comparison to species delimitation, integrating morphometric approaches with population genetic techniques via simultaneous ordinations. Early results suggest that several distinct speciation mechanisms operate within the British and Irish orchid flora, and challenge the validity of several 'Schedule 8' species. No meaningful differences exist between British Dactylorhiza 'lapponica' and D. 'traunsteineri' , and neither represents the same allopolyploid speciation event as D. traunsteineri from the type locality in Austria. AIso, contrary to the recent Atlas of the British & Irish flora, D. majalis s.s. does not occur in the British Isles. By contrast, three habitat 'races' within Gymnadenia merit species status. Epipactis 'youngiana' is not reliably distinct from E. helleborine, whereas the autogamous E. leptochila and E. dunensis both warrant species status, alongside E. sancta recently described from Lindisfame. Controversial taxa are either widely recognised but lack biological cohesion (Emperor's New Clothes species), rarely if ever recognised but possess biological cohesion (Cinderella species, including Robinson Crusoe species recently diverged on islands such as Dactylorhiza ebudensis), or are migrating northward, presumably in response to climate change (Bleriot species, such as Serapias parviflora). Recent arrivaIs by origination or migration are partly negated by extirpation of longer established species, notably Spiranthes aestivalis and arguably Epipogium aphyllum. Present evidence suggests that the orchid flora of the British Isles (excluding the iogeographically French Channel Islands) currently consists of52 species in 20 genera; these taxa are herein reclassified in anticipation of the third edition of Stace's Flora."

Molecular confirmation of Helosciadium×moorei (H. inundatum x H. nodiflorum; Apiaceae) from County Cork, Ireland / Stuart Desjardins in New Journal of botany, vol. 6, n°2-3 (Année 2016)

Public [article]  inNew Journal of botany > vol. 6, n°2-3 (Année 2016) . - pp. 90-97 Titre : Molecular confirmation of Helosciadium×moorei (H. inundatum x H. nodiflorum; Apiaceae) from County Cork, Ireland Type de document : Livre Auteurs : Stuart Desjardins, Auteur Année de publication : 2016 Article en page(s) : pp. 90-97 Langues : Anglais Catégories : [ZG] Royaume-Uni [Espèces (in biblio)] Apiaceae [Espèces (in biblio)] Apium [Espèces (in biblio)] Helosciadium x moorei Mots-clés : hybridation  phylogénétique Résumé : "Helosciadium x moorei (Apiaceae), collected from County Cork, Ireland, is confirmed as an interspecific hybrid between H. inundatum and H. nodiflorum. The origin of this taxon was investigated using sequence data from a maternally inherited chloroplast marker (rps16-trnK), sequence data from a biparentally inherited nuclear marker (ITS), and fluorescent in situ hybridisation with labelled total genomic probes (GISH). The maternally inherited chloroplast marker identified H. inundatum as the seed-parent, the biparentally inherited nuclear marker identified contributions from two parental species, H. inundatum and H. nodiflorum, and GISH identified two parental genomes in H.x moorei (2n = 22): 11 chromosomes from H. inundatum and 11 chromosomes from H. nodiflorum. No evidence of recombination between parental genomes was detected in the hybrid, which strongly indicates that it is an F1. This definitive molecular and cytogenetic study unequivocally establishes the parentage of H.x moorei for the first time, and confirms the suspicions of generations of botanists."
