Journal of Medicinal Plants Research Vol. 6(37), pp. 5048-5058, 26 September, 2012 Available online at http://www.academicjournals.org/JMPR DOI: 10.5897/JMPR11.1733 ISSN 1996-0875 ©2012 Academic Journals Full Length Research Paper Phylogenetic relationship and evolution analysis of the peony Paeonia species using multi-locus deoxyribonucleic acid (DNA) barcodes Yan-Lin Sun1,2 and Soon-Kwan Hong2,3* 1School of Life Sciences, Ludong University, Yantai, Shandong, 264-025, China. 2Department of Bio-Health Technology, Kangwon National University, Chuncheon, Kangwon, 200-701, Korea. 3Institute of Bioscience and Biotechnology, Kangwon National University, Chuncheon, Kangwon, 200-701, Korea. Accepted 6 July, 2012 Paeonia is a phylogenetically and taxonomically complex group. In this study, two chloroplast coding region of the matK and rbcL genes, two intergenic spacers, 5’ trnK-matK and matK-3’ trnK, the ribosomal RNA 18S and 5S genes, and the nuclear ribosomal DNA ITS gene were sequenced to study phylogenetic relationships of four Paeonia species. In the matK coding region, most nucleotide variations pointed at the divergence between Paeonia suffruticosa (MO) and other three species, strongly supporting the phylogenetic evolution of section Paeonia and section Moutan in the Paeonia genus; the variable sites of Paeonia lactiflora CHA1 accession compared to CHA accession were all identical to Paeonia obovata SHAN accession, indicating that CHA1 might be a hybrid result of CHA and SHAN. Another chloroplast coding region, rbcL showed lower variation rate and less phylogenetic information than the matK region in all four Paeonia species investigated in this study, while the 5S rRNA gene and nrDNA ITS region showed higher variation rate. -

Peziza and Pezizaceae Inferred from Multiple Nuclear Genes: RPB2, -Tubulin, and LSU Rdna
Molecular Phylogenetics and Evolution 36 (2005) 1–23 www.elsevier.com/locate/ympev Evolutionary relationships of the cup-fungus genus Peziza and Pezizaceae inferred from multiple nuclear genes: RPB2, -tubulin, and LSU rDNA Karen Hansen ¤, Katherine F. LoBuglio, Donald H. PWster Harvard University Herbaria, Cambridge, MA 02138, USA Received 5 May 2004; revised 17 December 2004 Available online 22 April 2005 Abstract To provide a robust phylogeny of Pezizaceae, partial sequences from two nuclear protein-coding genes, RPB2 (encoding the sec- ond largest subunit of RNA polymerase II) and -tubulin, were obtained from 69 and 72 specimens, respectively, to analyze with nuclear ribosomal large subunit RNA gene sequences (LSU). The three-gene data set includes 32 species of Peziza, and 27 species from nine additional epigeous and six hypogeous (truZe) pezizaceous genera. Analyses of the combined LSU, RPB2, and -tubulin data set using parsimony, maximum likelihood, and Bayesian approaches identify 14 Wne-scale lineages within Pezizaceae. Species of Peziza occur in eight of the lineages, spread among other genera of the family, conWrming the non-monophyly of the genus. Although parsimony analyses of the three-gene data set produced a nearly completely resolved strict consensus tree, with increased conWdence, relationships between the lineages are still resolved with mostly weak bootstrap support. Bayesian analyses of the three- gene data, however, show support for several more inclusive clades, mostly congruent with Bayesian analyses of RPB2. No strongly supported incongruence was found among phylogenies derived from the separate LSU, RPB2, and -tubulin data sets. The RPB2 region appeared to be the most informative single gene region based on resolution and clade support, and accounts for the greatest number of potentially parsimony informative characters within the combined data set, followed by the LSU and the -tubulin region. -

MycoKeys 60: 45–67. https://doi. org/10.3897/mycokeys.60.38186 Abstract Helvella species are ascomycetous macrofungi with saddle-shaped or cupulate apothecia. They are distri- buted worldwide and play an important ecological role as ectomycorrhizal symbionts. A recent multi-locus phylogenetic study of the genus suggested that the cupulate group of Helvella was in need of comprehen- sive revision. In this study, all the specimens of cupulate Helvella sensu lato with ribbed stipes deposited in HMAS were examined morphologically and molecularly. -

An Evolving Phylogenetically Based Taxonomy of Lichens and Allied Fungi
Opuscula Philolichenum, 11: 4-10. 2012. *pdf available online 3January2012 via (http://sweetgum.nybg.org/philolichenum/) An evolving phylogenetically based taxonomy of lichens and allied fungi 1 BRENDAN P. HODKINSON ABSTRACT. – A taxonomic scheme for lichens and allied fungi that synthesizes scientific knowledge from a variety of sources is presented. The system put forth here is intended both (1) to provide a skeletal outline of the lichens and allied fungi that can be used as a provisional filing and databasing scheme by lichen herbarium/data managers and (2) to announce the online presence of an official taxonomy that will define the scope of the newly formed International Committee for the Nomenclature of Lichens and Allied Fungi (ICNLAF). The online version of the taxonomy presented here will continue to evolve along with our understanding of the organisms. Additionally, the subfamily Fissurinoideae Rivas Plata, Lücking and Lumbsch is elevated to the rank of family as Fissurinaceae. KEYWORDS. – higher-level taxonomy, lichen-forming fungi, lichenized fungi, phylogeny INTRODUCTION Traditionally, lichen herbaria have been arranged alphabetically, a scheme that stands in stark contrast to the phylogenetic scheme used by nearly all vascular plant herbaria. The justification typically given for this practice is that lichen taxonomy is too unstable to establish a reasonable system of classification. However, recent leaps forward in our understanding of the higher-level classification of fungi, driven primarily by the NSF-funded Assembling the Fungal Tree of Life (AFToL) project (Lutzoni et al. 2004), have caused the taxonomy of lichen-forming and allied fungi to increase significantly in stability. This is especially true within the class Lecanoromycetes, the main group of lichen-forming fungi (Miadlikowska et al. -
Lichen Functional Trait Variation Along an East-West Climatic Gradient in Oregon and Among Habitats in Katmai National Park, Alaska
AN ABSTRACT OF THE THESIS OF Kaleigh Spickerman for the degree of Master of Science in Botany and Plant Pathology presented on June 11, 2015 Title: Lichen Functional Trait Variation Along an East-West Climatic Gradient in Oregon and Among Habitats in Katmai National Park, Alaska Abstract approved: ______________________________________________________ Bruce McCune Functional traits of vascular plants have been an important component of ecological studies for a number of years; however, in more recent times vascular plant ecologists have begun to formalize a set of key traits and universal system of trait measurement. Many recent studies hypothesize global generality of trait patterns, which would allow for comparison among ecosystems and biomes and provide a foundation for general rules and theories, the so-called “Holy Grail” of ecology. However, the majority of these studies focus on functional trait patterns of vascular plants, with a minority examining the patterns of cryptograms such as lichens. Lichens are an important component of many ecosystems due to their contributions to biodiversity and their key ecosystem services, such as contributions to mineral and hydrological cycles and ecosystem food webs. Lichens are also of special interest because of their reliance on atmospheric deposition for nutrients and water, which makes them particularly sensitive to air pollution. Therefore, they are often used as bioindicators of air pollution, climate change, and general ecosystem health. This thesis examines the functional trait patterns of lichens in two contrasting regions with fundamentally different kinds of data. To better understand the patterns of lichen functional traits, we examined reproductive, morphological, and chemical trait variation along precipitation and temperature gradients in Oregon. -

A Synopsis of the Saddle Fungi (Helvella: Ascomycota) in Europe – Species Delimitation, Taxonomy and Typification
Persoonia 39, 2017: 201–253 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/persoonia.2017.39.09 A synopsis of the saddle fungi (Helvella: Ascomycota) in Europe – species delimitation, taxonomy and typification I. Skrede1,*, T. Carlsen1, T. Schumacher1 Key words Abstract Helvella is a widespread, speciose genus of large apothecial ascomycetes (Pezizomycete: Pezizales) that are found in terrestrial biomes of the Northern and Southern Hemispheres. This study represents a beginning on molecular phylogeny assessing species limits and applying correct names for Helvella species based on type material and specimens in the Pezizales university herbaria (fungaria) of Copenhagen (C), Harvard (FH) and Oslo (O). We use morphology and phylogenetic systematics evidence from four loci – heat shock protein 90 (hsp), translation elongation factor alpha (tef), RNA polymerase II (rpb2) and the nuclear large subunit ribosomal DNA (LSU) – to assess species boundaries in an expanded sample of Helvella specimens from Europe. We combine the morphological and phylogenetic information from 55 Helvella species from Europe with a small sample of Helvella species from other regions of the world. Little intraspecific variation was detected within the species using these molecular markers; hsp and rpb2 markers provided useful barcodes for species delimitation in this genus, while LSU provided more variable resolution among the pertinent species. We discuss typification issues and identify molecular characteristics for 55 European Helvella species, designate neo- and epitypes for 30 species, and describe seven Helvella species new to science, i.e., H. alpicola, H. alpina, H. carnosa, H. danica, H. nannfeldtii, H. pubescens and H.
