  • Developing a Genetic Manipulation System for the Antarctic Archaeon, Halorubrum Lacusprofundi: Investigating Acetamidase Gene Function
    www.nature.com/scientificreports OPEN Developing a genetic manipulation system for the Antarctic archaeon, Halorubrum lacusprofundi: Received: 27 May 2016 Accepted: 16 September 2016 investigating acetamidase gene Published: 06 October 2016 function Y. Liao1, T. J. Williams1, J. C. Walsh2,3, M. Ji1, A. Poljak4, P. M. G. Curmi2, I. G. Duggin3 & R. Cavicchioli1 No systems have been reported for genetic manipulation of cold-adapted Archaea. Halorubrum lacusprofundi is an important member of Deep Lake, Antarctica (~10% of the population), and is amendable to laboratory cultivation. Here we report the development of a shuttle-vector and targeted gene-knockout system for this species. To investigate the function of acetamidase/formamidase genes, a class of genes not experimentally studied in Archaea, the acetamidase gene, amd3, was disrupted. The wild-type grew on acetamide as a sole source of carbon and nitrogen, but the mutant did not. Acetamidase/formamidase genes were found to form three distinct clades within a broad distribution of Archaea and Bacteria. Genes were present within lineages characterized by aerobic growth in low nutrient environments (e.g. haloarchaea, Starkeya) but absent from lineages containing anaerobes or facultative anaerobes (e.g. methanogens, Epsilonproteobacteria) or parasites of animals and plants (e.g. Chlamydiae). While acetamide is not a well characterized natural substrate, the build-up of plastic pollutants in the environment provides a potential source of introduced acetamide. In view of the extent and pattern of distribution of acetamidase/formamidase sequences within Archaea and Bacteria, we speculate that acetamide from plastics may promote the selection of amd/fmd genes in an increasing number of environmental microorganisms.

  • Large‐Scale Genomic Sequence Data Resolve the Deepest Divergences in the Legume Phylogeny and Support a Near‐Simultaneous Evolutionary Origin of All Six Subfamilies
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2020 Large‐scale genomic sequence data resolve the deepest divergences in the legume phylogeny and support a near‐simultaneous evolutionary origin of all six subfamilies Koenen, Erik J M ; Ojeda, Dario I ; Steeves, Royce ; Migliore, Jérémy ; Bakker, Freek T ; Wieringa, Jan J ; Kidner, Catherine ; Hardy, Olivier J ; Pennington, R Toby ; Bruneau, Anne ; Hughes, Colin E Abstract: Phylogenomics is increasingly used to infer deep‐branching relationships while revealing the complexity of evolutionary processes such as incomplete lineage sorting, hybridization/introgression and polyploidization. We investigate the deep‐branching relationships among subfamilies of the Leguminosae (or Fabaceae), the third largest angiosperm family. Despite their ecological and economic importance, a robust phylogenetic framework for legumes based on genome‐scale sequence data is lacking. We generated alignments of 72 chloroplast genes and 7621 homologous nuclear‐encoded proteins, for 157 and 76 taxa, respectively. We analysed these with maximum likelihood, Bayesian inference, and a multispecies coa- lescent summary method, and evaluated support for alternative topologies across gene trees. We resolve the deepest divergences in the legume phylogeny despite lack of phylogenetic signal across all chloroplast genes and the majority of nuclear genes. Strongly supported conflict in the remainder of nuclear genes is suggestive of incomplete lineage sorting. All six subfamilies originated nearly simultaneously, suggesting that the prevailing view of some subfamilies as ‘basal’ or ‘early‐diverging’ with respect to others should be abandoned, which has important implications for understanding the evolution of legume diversity and traits.

Since then the taxonomy of bacteria has been revolutionized several times. At present, 30 phyla belong to the domain “Bacteria”, which includes over 9600 species. Unlike many eukaryotes, bacteria lack complex morphological characters and practically phylogenetically informative fossils. It is partly due to these reasons that bacterial taxonomy is complicated.

  • Fieldtrip Manual for Plant Biodiversity
    Fieldtrip manual for Plant Biodiversity Ana Juan, Mª Ángeles Alonso, Alejandro Terrones, Joaquín Moreno, Joan Pérez & José Carlos Cristóbal Department of Environmental Sciences and Natural Resources Fieldtrip manual for Plant Biodiversity Introduction Plant Biodiversity is a subject taught during the second year of the Undergraduate Degree in Biology at the University of Alicante. The main principles about the diversity and morphology of the plants are mostly given during the theoretical classes. This fieldtrip practical manual, together with the laboratory sessions, gives the students an opportunity to see our most common wild plant species. Their direct observations allow them to identify properly the main botanical families, genera and species of our wild flora. This Fieldtrip manual for Plant Biodiversity has been written to enhance the understanding of plant diversity and to identify the different ecological conditions for plant species. Students have to understand that “plants do not grow everywhere”. Most of our natural flora, and specially the endemic one, requires specific environmental conditions to grow. So, the objectives of these fieldtrips are to identify wild flora and to recognise the ecological habitats where many of the identified plant species live. According to the official organisation of the subject Plant Biodiversity at the University of Alicante, nine hours correspond to two field practical sessions, which last 4 and 5 hours, respectively. This manual has been organised in only two chapters. Each chapter includes the description of the places to visit: - Chapter 1. Fieldtrip “Urbanova”: study of coastal sand dunes and salt marshes. - Chapter 2. Fieldtrip “Estación Biológica de Torretes”: study of mountain habitats.

E. Gryzon, 1070 Bruxelles, Belgium Received 21 July 2014; accepted 21 July 2014 Available online 4 August 2014 Abstract Pseudomonas bacteria are ubiquitous Gram-negative and aerobic microorganisms that are known to harbor metal resistance mechanisms such as efflux pumps and intracellular redox enzymes. Specific Pseudomonas bacteria have been quantified in some metal-contaminated environ- ments, but the entire Pseudomonas population has been poorly investigated under these conditions, and the link with metal bioavailability was not previously examined. In the present study, quantitative PCR and cell cultivation were used to monitor and characterize the Pseudomonas population at 4 different sediment sites contaminated with various levels of metals. At the same time, total metals and metal bioavailability (as estimated using an HCl 1 M extraction) were measured. It was found that the total level of Pseudomonas, as determined by qPCR using two different genes (oprI and the 16S rRNA gene), was positively and significantly correlated with total and HCl-extractable Cu, Co, Ni, Pb and Zn, with high correlation coefficients (>0.8).

  • Aquatic Microbial Ecology 80:15
    The following supplement accompanies the article Isolates as models to study bacterial ecophysiology and biogeochemistry Åke Hagström*, Farooq Azam, Carlo Berg, Ulla Li Zweifel *Corresponding author: [email protected] Aquatic Microbial Ecology 80: 15–27 (2017) Supplementary Materials & Methods The bacteria characterized in this study were collected from sites at three different sea areas; the Northern Baltic Sea (63°30’N, 19°48’E), Northwest Mediterranean Sea (43°41'N, 7°19'E) and Southern California Bight (32°53'N, 117°15'W). Seawater was spread onto Zobell agar plates or marine agar plates (DIFCO) and incubated at in situ temperature. Colonies were picked and plate- purified before being frozen in liquid medium with 20% glycerol. The collection represents aerobic heterotrophic bacteria from pelagic waters. Bacteria were grown in media according to their physiological needs of salinity. Isolates from the Baltic Sea were grown on Zobell media (ZoBELL, 1941) (800 ml filtered seawater from the Baltic, 200 ml Milli-Q water, 5g Bacto-peptone, 1g Bacto-yeast extract). Isolates from the Mediterranean Sea and the Southern California Bight were grown on marine agar or marine broth (DIFCO laboratories). The optimal temperature for growth was determined by growing each isolate in 4ml of appropriate media at 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50o C with gentle shaking. Growth was measured by an increase in absorbance at 550nm. Statistical analyses The influence of temperature, geographical origin and taxonomic affiliation on growth rates was assessed by a two-way analysis of variance (ANOVA) in R (http://www.r-project.org/) and the “car” package.

Gostin ar , P. Zalar , I. Raymond-Bouchard , J. Zajc , C. P. McKay , N. Gunde-Cimerman and L. G. Whyte 1 The Author(s) 2021 The novel extremophilic yeast Rhodotorula frigidialcoholis, formerly R. JG1b, was isolated from ice-cemented permafrost in University Valley (Antarctic), one of coldest and driest environments on Earth. Phenotypic and phylogenetic analyses classified R. frigidialcoholis as a novel species. To characterize its cold-adaptive strategies, we performed mRNA and sRNA transcriptomic analyses, phenotypic profiling, and assessed ethanol production at 0 and 23 °C. Downregulation of the ETC and citrate cycle genes, overexpression of fermentation and pentose phosphate pathways genes, growth without reduction of tetrazolium dye, and our discovery of ethanol production at 0 °C indicate that R. frigidialcoholis induces a metabolic switch from respiration to ethanol fermentation as adaptation in Antarctic permafrost. This is the first report of microbial ethanol fermentation utilized as the major energy pathway in response to cold and the coldest temperature reported for natural ethanol production. R. frigidialcoholis increased its diversity and abundance of sRNAs when grown at 0 versus 23 °C. This was consistent with increase in transcription of Dicer, a key protein for sRNA processing. Our results strongly imply that post-transcriptional regulation of gene expression and mRNA silencing may be a novel evolutionary fungal adaptation in the cryosphere.
