Recently, rRNA gene phylogenetic analyses of two atypical parasitic fungi with amoeboid zoospores and long kinetosomes, the sanchytrids Amoeboradix gromovi and San- chytrium tribonematis, showed that they formed a monophyletic group without close affinity with known fungal clades. Here, we sequence single-cell genomes for both species to assess their phylogenetic position and evolution. Phylogenomic analyses using different protein datasets and a comprehensive taxon sampling result in an almost fully-resolved fungal tree, with Chytridiomycota as sister to all other fungi, and sanchytrids forming a well-supported, fast-evolving clade sister to Blastocladiomycota. Comparative genomic analyses across fungi and their allies (Holomycota) reveal an atypically reduced metabolic repertoire for sanchy- trids. We infer three main independent flagellum losses from the distribution of over 60 flagellum-specific proteins across Holomycota. Based on sanchytrids’ phylogenetic position and unique traits, we propose the designation of a novel phylum, Sanchytriomycota. In addition, our results indicate that most of the hyphal morphogenesis gene repertoire of multicellular fungi had already evolved in early holomycotan lineages. 1 Ecologie Systématique Evolution, CNRS, Université Paris-Saclay, AgroParisTech, Orsay, France. 2 Zoological Institute, Russian Academy of Sciences, St. ✉ Petersburg, Russia. 3 St.

  • Biological Classification Chapter 2
    16 BIOLOGY CHAPTER 2 BIOLOGICAL CLASSIFICATION 2.1 Kingdom Monera Since the dawn of civilisation, there have been many attempts to classify living organisms. It was done instinctively not using criteria that were 2.2 Kingdom Protista scientific but borne out of a need to use organisms for our own use – for 2.3 Kingdom Fungi food, shelter and clothing. Aristotle was the earliest to attempt a more 2.4 Kingdom Plantae scientific basis for classification. He used simple morphological characters to classify plants into trees, shrubs and herbs. He also divided animals 2.5 Kingdom into two groups, those which had red blood and those that did not. Animalia In Linnaeus' time a Two Kingdom system of classification with 2.6 Viruses, Viroids Plantae and Animalia kingdoms was developed that included all plants and Lichens and animals respectively. This system was used till very recently. This system did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organisms and photosynthetic (green algae) and non-photosynthetic (fungi) organisms. Classification of organisms into plants and animals was easily done and was easy to understand, inspite, a large number of organisms did not fall into either category. Hence the two kingdom classification used for a long time was found inadequate. A need was also felt for including, besides gross morphology, other characteristics like cell structure, nature of wall, mode of nutrition, habitat, methods of reproduction, evolutionary relationships, etc. Classification systems for the living organisms have hence, undergone several changes over time. Though plant and animal kingdoms have been a constant under all different systems, the understanding of what groups/organisms be included under these kingdoms have been changing; the number and nature of other kingdoms have also been understood differently by different scientists over time.

  • Clade (Kingdom Fungi, Phylum Chytridiomycota)
    TAXONOMIC STATUS OF GENERA IN THE “NOWAKOWSKIELLA” CLADE (KINGDOM FUNGI, PHYLUM CHYTRIDIOMYCOTA): PHYLOGENETIC ANALYSIS OF MOLECULAR CHARACTERS WITH A REVIEW OF DESCRIBED SPECIES by SHARON ELIZABETH MOZLEY (Under the Direction of David Porter) ABSTRACT Chytrid fungi represent the earliest group of fungi to have emerged within the Kingdom Fungi. Unfortunately despite the importance of chytrids to understanding fungal evolution, the systematics of the group is in disarray and in desperate need of revision. Funding by the NSF PEET program has provided an opportunity to revise the systematics of chytrid fungi with an initial focus on four specific clades in the order Chytridiales. The “Nowakowskiella” clade was chosen as a test group for comparing molecular methods of phylogenetic reconstruction with the more traditional morphological and developmental character system used for classification in determining generic limits for chytrid genera. Portions of the 18S and 28S nrDNA genes were sequenced for isolates identified to genus level based on morphology to seven genera in the “Nowakowskiella” clade: Allochytridium, Catenochytridium, Cladochytrium, Endochytrium, Nephrochytrium, Nowakowskiella, and Septochytrium. Bayesian, parsimony, and maximum likelihood methods of phylogenetic inference were used to produce trees based on one (18S or 28S alone) and two-gene datasets in order to see if there would be a difference depending on which optimality criterion was used and the number of genes included. In addition to the molecular analysis, taxonomic summaries of all seven genera covering all validly published species with a listing of synonyms and questionable species is provided to give a better idea of what has been described and the morphological and developmental characters used to circumscribe each genus.

  • Evolution and Phylogeny of Fungi
    Dr. Archana Dutta Study material for M.Sc Botany- First Semester ​ Assistant Professor(Guest Faculty) Dept. of Botany, MLT College, Saharsa [email protected] Mob No. - 9065558829 Evolution And Phylogeny Of Fungi Fungi have ancient origins, with evidence indicating they likely first appeared about one billion years ago, though the fossil record of fungi is scanty. Fungal hyphae evident within the tissues of the oldest plant fossils confirm that fungi are an extremely ancient group. Indeed, some of the oldest terrestrial plantlike fossils known, called Prototaxites, which were common in all parts of the world throughout the Devonian Period (419.2 million to 358.9 million years ago), are interpreted as large saprotrophic fungi (possibly even Basidiomycota). Fossils of Tortotubus protuberans, a filamentous fungus, date to the early Silurian Period (440 million years ago) and are thought to be the oldest known fossils of a terrestrial organism. However, in the absence of an extensive fossil record, biochemical characters have served as useful markers in mapping the probable evolutionary relationships of fungi. Fungal groups can be related by cell wall composition (i.e., presence of both chitin and alpha-1,3 and alpha-1,6-glucan), organization of tryptophan enzymes, and synthesis of lysine (i.e., by the aminoadipic acid pathway). Molecular phylogenetic analyses that became possible during the 1990s have greatly contributed to the understanding of fungal origins and evolution. At first, these analyses generated evolutionary trees by comparing a single gene sequence, usually the small subunit ribosomal RNA gene (SSU rRNA). Since then, information from several protein-coding genes has helped correct discrepancies, and phylogenetic trees of fungi are currently built using a wide variety of data largely, but not entirely, molecular in nature.

E-mail : [email protected] Received 21 November 2003; accepted 28 January 2004. Rhizophlyctis rosea was found in 44% of 59 soil samples from national parks, urban reserves and gardens, and agricultural lands of eastern New South Wales, Australia. As some of the soils are periodically dry and hot, we examined possible mechanisms that enable survival in stressful environments such as agricultural lands. Air-dried thalli of R. rosea in soil and pure cultures of R. rosea, two isolates of Allomyces anomalus, one isolate of Catenaria sp., one of Catenophlyctis sp. and one of Spizellomyces sp. recovered following incubation at 90 xC for two days. Powellomyces sp. recovered following incubation at 80 x. Sporangia of all seven fungi shrank during air-drying, and immediately returned to turgidity when rehydrated. Some sporangia of R. rosea released zoospores immediately upon rehydration. These data indicate that some Chytridiomycota have resistant structures that enable survival through periodic drying and high summer temperatures typical of soils used for cropping. Eleven Chytridiomycota isolated from soil did not survive either drying or heat. Neither habitat of the fungus nor morphological type correlated with the capacity to tolerate drying and heat.

Hibbett, Corresponding Author's Institution: Clark University First Author: David S Hibbett, PhD Order of Authors: David S Hibbett, PhD; David S. Hibbett Manuscript Region of Origin: UNITED STATES Abstract: A comprehensive phylogenetic classification of the kingdom Fungi is proposed, with reference to recent molecular phylogenetic analyses, and with input from diverse members of the fungal taxonomic community. The classification includes 195 taxa, down to the level of order, of which 19 are described or validated here: Dikarya subkingdom nov.; Chytridiomycota, Neocallimastigomycota phyla nov.; Agaricomycetes, Dacrymycetes, Monoblepharidomycetes, Neocallimastigomycetes, Tremellomycetes class. nov.; Eurotiomycetidae, Lecanoromycetidae, Mycocaliciomycetidae subclass. nov.; Acarosporales, Corticiales, Baeomycetales, Candelariales, Gloeophyllales, Melanosporales, Trechisporales, Umbilicariales ords. nov. The clade containing Ascomycota and Basidiomycota is classified as subkingdom Dikarya, reflecting the putative synapomorphy of dikaryotic hyphae. The most dramatic shifts in the classification relative to previous works concern the groups that have traditionally been included in the Chytridiomycota and Zygomycota.

  • CHAPTER 25. Phylogeny and Evolution
    CHAPTER 25. Phylogeny and Evolution Not long after taxonomists recognized that among the saprolegniaceous fungi there were homologous groups possessing similar devices for insuring reproduction, they began industriously arranging these groups into hierarchical clusters to suggest relationships. Although the resulting phylogenetic schemes were fashioned around the relatively simple structure of the individual species, mycologists weighted differently the few available morphological similarities and differences. The family unit itself has not escaped attempts at phylogenetic speculation, and at the suprafamilial level, concepts of relationships have touched upon the origin of the fungi as a whole and of the Oomycetes (Mastigomycetes) in particular. In fact, more attention has been paid to the phylogenetic derivation of the larger taxonomic units in which the watermolds are placed than to the infrafamilial components. For example, Margulis (1968), who proposed that the eukaryotic cell arose through a series of specific symbioses with prokaryotes, suggested that animals and most fungi had a protozoan ancestry. On the other hand, Klein and Cronquist (1967) saw the Oomycetes as misfits in the otherwise cohesive unit of organisms recognizable as the fungi. These authors thought that oomycete ancestry was traceable to a different group of algae than that from which the fungi allegedly arose. Klein (1970) adopted essentially this same view. Chiefly, the phylogeny of the saprolegniaceous fungi has long been thought to be woven closely with some ancestral alga, and the morphological resemblance of watermolds to certain existing algal groups is usually advanced to testify to the soundness of this view. The propositions that derive the Saprolegniaceae (or Oomycetes in a broader sense) from algae has, of course, gone beyond simply selecting these chlorophyllous plants to be likely ancestors (C.

  • 21St Century Guidebook to Fungi OUTLINE CLASSIFICATION of FUNGI
    Outline Classification of Fungi: Page 1 21st Century Guidebook to Fungi OUTLINE CLASSIFICATION OF FUNGI Evolution and phylogeny Until the latter half of the twentieth century fungi were classified in the Plant Kingdom (strictly speaking into the subkingdom Cryptogamia, Division Fungi, subdivision Eumycotina) and were separated into four classes: the Phycomycetes, Ascomycetes, Basidiomycetes, and Deuteromycetes (the latter also known as Fungi Imperfecti because they lacked a sexual cycle). These traditional groups of ‘fungi’ were largely defined by the morphology of their sexual organs, whether or not their hyphae had cross-walls (septa), and the ploidy (degree of repetition of the basic number of chromosomes) of nuclei in their vegetative mycelium. The slime moulds, all grouped in the subdivision Myxomycotina, were also included in Division Fungi. Around the middle of the twentieth century the three major kingdoms of multicellular eukaryotes were finally recognised as being absolutely distinct; the crucial character difference being the mode of nutrition: animals (whether single cells or multicellular) engulf food; plants photosynthesise; and fungi excrete digestive enzymes and absorb externally- digested nutrients. Other differences can be added to these. For example: in their cell membranes animals use cholesterol, fungi use ergosterol; in their cell walls, plants use cellulose (a glucose polymer), fungi use chitin (a glucosamine polymer); recent genomic surveys show that plant genomes lack gene sequences that are crucial in animal development, and vice-versa, and fungal genomes have none of the sequences that are important in controlling multicellular development in animals or plants. This latter point implies that animals, plants and fungi separated at a unicellular grade of organisation.

  • Updates on the Taxonomy of Mucorales with an Emphasis on Clinically Important Taxa
    Journal of Fungi Review Updates on the Taxonomy of Mucorales with an Emphasis on Clinically Important Taxa Grit Walther 1,*, Lysett Wagner 1 and Oliver Kurzai 1,2 1 German National Reference Center for Invasive Fungal Infections, Leibniz Institute for Natural Product Research and Infection Biology – Hans Knöll Institute, 07745 Jena, Germany; [email protected] (L.W.); [email protected] (O.K.) 2 Institute for Hygiene and Microbiology, University of Würzburg, 97080 Würzburg, Germany * Correspondence: [email protected]; Tel.: +49-3641-5321038 Received: 17 September 2019; Accepted: 11 November 2019; Published: 14 November 2019 Abstract: Fungi of the order Mucorales colonize all kinds of wet, organic materials and represent a permanent part of the human environment. They are economically important as fermenting agents of soybean products and producers of enzymes, but also as plant parasites and spoilage organisms. Several taxa cause life-threatening infections, predominantly in patients with impaired immunity. The order Mucorales has now been assigned to the phylum Mucoromycota and is comprised of 261 species in 55 genera. Of these accepted species, 38 have been reported to cause infections in humans, as a clinical entity known as mucormycosis. Due to molecular phylogenetic studies, the taxonomy of the order has changed widely during the last years. Characteristics such as homothallism, the shape of the suspensors, or the formation of sporangiola are shown to be not taxonomically relevant. Several genera including Absidia, Backusella, Circinella, Mucor, and Rhizomucor have been amended and their revisions are summarized in this review. Medically important species that have been affected by recent changes include Lichtheimia corymbifera, Mucor circinelloides, and Rhizopus microsporus.
