Recently, it was reported that calcium affects polyphosphate and lipid accumulation in fungi. The purpose of this study was to assess the effect of calcium on the accumulation of lipids and polyphosphate for six oleaginous Mucoromycota fungi grown under different phosphorus/pH conditions. A Duetz microtiter plate system (Duetz MTPS) was used for the cultivation. The compositional profile of the microbial biomass was recorded using Fourier-transform infrared spectroscopy, the high throughput screening extension (FTIR-HTS). -
Succession and Persistence of Microbial Communities and Antimicrobial Resistance Genes Associated with International Space Stati
Singh et al. Microbiome (2018) 6:204 https://doi.org/10.1186/s40168-018-0585-2 RESEARCH Open Access Succession and persistence of microbial communities and antimicrobial resistance genes associated with International Space Station environmental surfaces Nitin Kumar Singh1, Jason M. Wood1, Fathi Karouia2,3 and Kasthuri Venkateswaran1* Abstract Background: The International Space Station (ISS) is an ideal test bed for studying the effects of microbial persistence and succession on a closed system during long space flight. Culture-based analyses, targeted gene-based amplicon sequencing (bacteriome, mycobiome, and resistome), and shotgun metagenomics approaches have previously been performed on ISS environmental sample sets using whole genome amplification (WGA). However, this is the first study reporting on the metagenomes sampled from ISS environmental surfaces without the use of WGA. Metagenome sequences generated from eight defined ISS environmental locations in three consecutive flights were analyzed to assess the succession and persistence of microbial communities, their antimicrobial resistance (AMR) profiles, and virulence properties. Metagenomic sequences were produced from the samples treated with propidium monoazide (PMA) to measure intact microorganisms. Results: The intact microbial communities detected in Flight 1 and Flight 2 samples were significantly more similar to each other than to Flight 3 samples. Among 318 microbial species detected, 46 species constituting 18 genera were common in all flight samples. Risk group or biosafety level 2 microorganisms that persisted among all three flights were Acinetobacter baumannii, Haemophilus influenzae, Klebsiella pneumoniae, Salmonella enterica, Shigella sonnei, Staphylococcus aureus, Yersinia frederiksenii,andAspergillus lentulus.EventhoughRhodotorula and Pantoea dominated the ISS microbiome, Pantoea exhibited succession and persistence. K. pneumoniae persisted in one location (US Node 1) of all three flights and might have spread to six out of the eight locations sampled on Flight 3. -

During a study of the fungal diversity of 12 undiscovered taxa in Korea, two mucoralean strains, CNUFC-GWD3-9 and CNUFC-EGF1-4, were 13 isolated from specific habitats including freshwater and fecal samples, respectively, in Korea. The 14 strains were analyzed both for morphology and phylogeny based on the internal transcribed 15 spacer (ITS) and large subunit (LSU) of 28S ribosomal DNA regions. On the basis of their 16 morphological characteristics and sequence analyses, isolates CNUFC-GWD3-9 and CNUFC- 17 EGF1-4 were confirmed to be Gilbertella persicaria and Pilobolus crystallinus, respectively.To the 18 best of our knowledge, there are no published literature records of these two genera in Korea. 19 Keywords: Gilbertella persicaria; Pilobolus crystallinus; mucoralean fungi; phylogeny; morphology; 20 undiscovered taxa 21 22 1. Introduction 23 Previously, taxa of the former phylum Zygomycota were distributed among the phylum 24 Glomeromycota and four subphyla incertae sedis, including Mucoromycotina, Kickxellomycotina, 25 Zoopagomycotina, and Entomophthoromycotina [1]. -

Cooper and Thomas M. Jeitner Received: 26 October 2016; Accepted: 24 February 2017; Published: 6 March 2017 Abstract: Ornithine δ-aminotransferase (OAT, E.C. 2.6.1.13) catalyzes the transfer of the δ-amino group from ornithine (Orn) to α-ketoglutarate (aKG), yielding glutamate-5-semialdehyde and glutamate (Glu), and vice versa. In mammals, OAT is a mitochondrial enzyme, mainly located in the liver, intestine, brain, and kidney. In general, OAT serves to form glutamate from ornithine, with the notable exception of the intestine, where citrulline (Cit) or arginine (Arg) are end products. -
Fungal Evolution: Major Ecological Adaptations and Evolutionary Transitions
Biol. Rev. (2019), pp. 000–000. 1 doi: 10.1111/brv.12510 Fungal evolution: major ecological adaptations and evolutionary transitions Miguel A. 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). -

However, in cucumber (Cucumis sativus L.), very little is known about the roles of SAP gene family members in regulating plant growth, development, and stress responses. In this study, a total of 12 SAP genes (named as CsSAP1-CsSAP12) were identified in the cucumber genome, which were unevenly distributed on six chromosomes. Gene duplication analysis detected one tandem duplication and two segmental duplication events. Phylogenetic analysis of SAP proteins from cucumber and other plants suggested that they could be divided into seven groups (sub-families), and proteins in the same group generally had the same arrangement of AN1 (ZnF-AN1) and A20 (ZnF-A20) domains. -

The Action Mechanism of Daptomycin
The final publication is available at Elsevier via http://dx.doi.org/10.1016/j.bmc.2016.05.052 © 2016. The Action Mechanism of Daptomycin Scott D. Taylor, Michael Palmer Department of Chemistry, University of Waterloo, Waterloo, ON N2L 3G1, Canada Abstract Daptomycin is a lipopeptide antibiotic produced by the soil bacterium Strep- tomyces roseosporus that is clinically used to treat severe infections with Gram- positive bacteria. In this review, we discuss the mode of action of this impor- tant antibiotic. Although daptomycin is structurally related to amphomycin and similar lipopeptides that inhibit peptidoglycan biosynthesis, experimen- tal studies have not produced clear evidence that daptomycin shares their action mechanism. Instead, the best characterized effect of daptomycin is the permeabilization and depolarization of the bacterial cell membrane. This ac- tivity, which can account for daptomycin’s bactericidal effect, correlates with the level of phosphatidylglycerol (PG) in the membrane. Accordingly, reduced synthesis of PG or its increased conversion to lysyl-PG promotes bacterial re- sistance to daptomycin. While other resistance mechanisms suggest that dap- tomycin may indeed directly interfere with cell wall synthesis or cell division, such effects still await direct experimental confirmation. Daptomycin’s com- plex structure and biosynthesis have hampered the analysis of its structure activity relationships. Novel methods of total synthesis, including a recent one that is carried out entirely on a solid phase, will enable a more thorough and systematic exploration of the sequence space.
