Variable Absorption of Mutational Trends by Prion-Forming Domains During Saccharomycetes Evolution
Variable absorption of mutational trends by prion-forming domains during Saccharomycetes evolution Paul M. Harrison Department of Biology, McGill University, Monteal, Quebec, Canada ABSTRACT Prions are self-propagating alternative states of protein domains. They are linked to both diseases and functional protein roles in eukaryotes. Prion-forming domains in Saccharomyces cerevisiae are typically domains with high intrinsic protein disorder (i.e., that remain unfolded in the cell during at least some part of their functioning), that are converted to self-replicating amyloid forms. S. cerevisiae is a member of the fungal class Saccharomycetes, during the evolution of which a large population of prion-like domains has appeared. It is still unclear what principles might govern the molecular evolution of prion-forming domains, and intrinsically disordered domains generally. Here, it is discovered that in a set of such prion-forming domains some evolve in the fungal class Saccharomycetes in such a way as to absorb general mutation biases across millions of years, whereas others do not, indicating a spectrum of selection pressures on composition and sequence. Thus, if the bias-absorbing prion formers are conserving a prion-forming capability, then this capability is not interfered with by the absorption of bias changes over the duration of evolutionary epochs. Evidence is discovered for selective constraint against the occurrence of lysine residues (which likely disrupt prion formation) in S. cerevisiae prion-forming domains as they evolve across Saccharomycetes. These results provide a case study of the absorption of mutational trends by compositionally biased domains, and suggest methodology for assessing selection pressures on the composition of intrinsically disordered regions. -
Swim Bladder Mycosis in Farmed Rainbow Trout Oncorhynchus Mykiss Caused by Phoma Herbarum and Experimental Verification of Pathogenicity

At necropsy, the gross lesions included a thick- ened swim bladder wall, and the posterior portion of the swim bladder was enlarged due to mas- sive hyperplasia of muscle. A microscopic wet mount examination of the swim bladder contents revealed abundant septate hyphae, and histopathological examination showed periodic acid- Schiff-positive mycelia in the lumen and wall of the swim bladder. Histopathological examination of the thickened posterior swim bladder revealed muscle hyperplasia with expansion by inflam- matory cells. The causative agent was identified as Phoma herbarum through morphological an - alysis and DNA sequencing. The disease was reproduced in rainbow trout fingerlings using intra - peritoneal injection of a spore suspension. Necropsy in dead and moribund fish revealed ex tensive congestion and haemorrhages in the serosa of visceral organs and in liver and abdominal serosan- guinous fluid. Histopathological examination showed severe hepatic congestion, sinusoidal dilata- tion, Kupffer cell reactivity, leukostasis and degenerative changes. -

Naranjo-Ortiz1 and Toni Gabaldon´ 1,2,3∗ 1Department of Genomics and Bioinformatics, Centre for Genomic Regulation (CRG), The Barcelona Institute of Science and Technology, Dr. Aiguader 88, Barcelona 08003, Spain 2 Department of Experimental and Health Sciences, Universitat Pompeu Fabra (UPF), 08003 Barcelona, Spain 3ICREA, Pg. Lluís Companys 23, 08010 Barcelona, Spain ABSTRACT Fungi are a highly diverse group of heterotrophic eukaryotes characterized by the absence of phagotrophy and the presence of a chitinous cell wall. While unicellular fungi are far from rare, part of the evolutionary success of the group resides in their ability to grow indefinitely as a cylindrical multinucleated cell (hypha). Armed with these morphological traits and with an extremely high metabolical diversity, fungi have conquered numerous ecological niches and have shaped a whole world of interactions with other living organisms. Herein we survey the main evolutionary and ecological processes that have guided fungal diversity. We will first review the ecology and evolution of the zoosporic lineages and the process of terrestrialization, as one of the major evolutionary transitions in this kingdom. Several plausible scenarios have been proposed for fungal terrestralization and we here propose a new scenario, which considers icy environments as a transitory niche between water and emerged land. We then focus on exploring the main ecological relationships of Fungi with other organisms (other fungi, protozoans, animals and plants), as well as the origin of adaptations to certain specialized ecological niches within the group (lichens, black fungi and yeasts). -

Read Full License Page 1/18 Abstract High-throughput sequencing technology was used to analyze the fungal community structure and its association with the cause of decay on the wooden pillars of an ancient archway in Beijing. The dominant fungi on the rotten pillars belonged to Ascomycetes regardless of the sampling position. Compared with the fungal community composition of discolored wood previously studied, the proportion of Basidiomycetes in rotten wood pillars increased at the highest value of 37.9%. High-throughput sequencing showed that the main fungi in the rst pillar were Ascomycetes ( Phoma , Lecythophora , and Scedosporium ) and Basidiomycetes (Sporidiobolales). Ascomycetes Lecythophora and Basidiomycetes Cryptcoccus and Postia were the main fungi in pillar 2. Phoma , Trichoderma, and Entoloma were isolated from pillar 1, whereas Alternaria and Phaeosphaeriaceae were obtained from pillar 2 using culture isolation. Traditional isolation failed to obtain all dominant fungi. The importance of high-throughput sequencing technology in ancient wooden structure building biodeterioration analysis was further explained. At the three sampling sites, the contact-ground fungal community composition was similar to that of in-ground wood, whereas above-ground fungal community composition was signicantly different from the other two sites. -

Gareth Jones, [email protected] Abstract: Phylogenetic analyses of four nuclear genes, namely the large and small subunits of the nuclear ribosomal RNA, transcription elongation factor 1-alpha and the second largest RNA polymerase II subunit, established that the ecological group of marine bitunicate ascomycetes has representatives in the orders Capnodiales, Hysteriales, Jahnulales, Mytilinidiales, Patellariales and Pleosporales. Most of the fungi sequenced were intertidal mangrove taxa and belong to members of 12 families in the Pleosporales: Aigialaceae, Didymellaceae, Leptosphaeriaceae, Lenthitheciaceae, Lophiostomataceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae, Phaeosphaeriaceae, Pleosporaceae, Testudinaceae and Trematosphaeriaceae. Two new families are described: Aigialaceae and Morosphaeriaceae, and three new genera proposed: Halomassarina, Morosphaeria and Rimora. -

The function of spores is to disperse fungi to new areas and to get them through difficult periods. This Spores also makes them important vehicles for food contamination. Formation of spores is a complex process that is Conidia regulated by the cooperation of different transcription factors.

Fungi can produce different types of spores, sexual and asexually, within the same colony. The absence or Development Stress resistance presence of sexual spore formation has led to a dual nomenclature for fungi. Molecular techniques have led to a Heat-resistant fungi revision of this nomenclature. A number of fungal species form sexual spores, which are exceptionally stress- resistant and survive pasteurization and other treatments.

Results: In order to develop means of biological control appropriate to the conditions of southern Tunisia, the efficacy of the native strain of the predator Nesidiocoris tenuis Reuter (Hemiptera: Miridae) and two entomopathogenic fungi (EPF) Beauveria bassiana and Lecanicillium muscarium was tested against Bemisia tabaci (Gennadius). Indeed, the introduction of N. tenuis in doses of 1, 2, 3, or 4 nymphs per tobacco plant infested by the whitefly led to highly significant reduction in the population of B. tabaci, than the control devoid of predator. The efficacy of N. tenuis was very high against nymphs and adults of B. tabaci at all doses per plant with a rate of 98%. Likewise, B. bassiana and L. muscarium, compared to an untreated control, showed a very significant efficacy against larvae and adults of B. tabaci. In addition, the number of live nymphs of N. tenuis treated directly or introduced on nymphs of B. tabaci treated with the EPF remained relatively high, exceeding 24.8 nymphs per cage compared to the control (28.6). -

Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades. -
The Fungi Constitute a Major Eukary- Members of the Monophyletic Kingdom Fungi ( Fig
American Journal of Botany 98(3): 426–438. 2011. T HE FUNGI: 1, 2, 3 … 5.1 MILLION SPECIES? 1 Meredith Blackwell 2 Department of Biological Sciences; Louisiana State University; Baton Rouge, Louisiana 70803 USA • Premise of the study: Fungi are major decomposers in certain ecosystems and essential associates of many organisms. They provide enzymes and drugs and serve as experimental organisms. In 1991, a landmark paper estimated that there are 1.5 million fungi on the Earth. Because only 70 000 fungi had been described at that time, the estimate has been the impetus to search for previously unknown fungi. Fungal habitats include soil, water, and organisms that may harbor large numbers of understudied fungi, estimated to outnumber plants by at least 6 to 1. More recent estimates based on high-throughput sequencing methods suggest that as many as 5.1 million fungal species exist. • Methods: Technological advances make it possible to apply molecular methods to develop a stable classifi cation and to dis- cover and identify fungal taxa. • Key results: Molecular methods have dramatically increased our knowledge of Fungi in less than 20 years, revealing a mono- phyletic kingdom and increased diversity among early-diverging lineages. Mycologists are making signifi cant advances in species discovery, but many fungi remain to be discovered. • Conclusions: Fungi are essential to the survival of many groups of organisms with which they form associations. They also attract attention as predators of invertebrate animals, pathogens of potatoes and rice and humans and bats, killers of frogs and crayfi sh, producers of secondary metabolites to lower cholesterol, and subjects of prize-winning research.
