Pieper, Ramón Rosselló-Móra, Jesús Sánchez, Jana Seifert and Manuel Ferrer 10 Supporting Online Material includes Text (Supporting Materials and Methods) Tables S1 to S9 Figures S1 to S7 1 SUPPORTING TEXT Supporting Materials and Methods Soil characterisation Soil pH was measured in a suspension of soil and water (1:2.5) with a glass electrode, and 5 electrical conductivity was measured in the same extract (diluted 1:5). Primary soil characteristics were determined using standard techniques, such as dichromate oxidation (organic matter content), the Kjeldahl method (nitrogen content), the Olsen method (phosphorus content) and a Bernard calcimeter (carbonate content). The Bouyoucos Densimetry method was used to establish textural data. Exchangeable cations (Ca, Mg, K and 10 Na) extracted with 1 M NH 4Cl and exchangeable aluminium extracted with 1 M KCl were determined using atomic absorption/emission spectrophotometry with an AA200 PerkinElmer analyser. The effective cation exchange capacity (ECEC) was calculated as the sum of the values of the last two measurements (sum of the exchangeable cations and the exchangeable Al). Analyses were performed immediately after sampling. 15 Hydrocarbon analysis Extraction (5 g of sample N and Nbs) was performed with dichloromethane:acetone (1:1) using a Soxtherm extraction apparatus (Gerhardt GmbH & Co. -

Abstract N-210 Contact Information The majority of the soil’s biosphere containins biodiveristy that remains yet to be discovered. The occurrence of novel bacterial phyla in soil, as well as the phylogenetic diversity within bacterial phyla with few cultured representatives (e.g. Acidobacteria, Anne Spain Dr. Mostafa S.Elshahed Verrucomicrobia, and Gemmatimonadetes) have been previously well documented. However, few studies have focused on the Composition, Diversity, and Novelty within Soil Proteobacteria Department of Botany and Microbiology Department of Microbiology and Molecular Genetics novel phylogenetic diversity within phyla containing numerous cultured representatives. Here, we present a detailed University of Oklahoma Oklahoma State University phylogenetic analysis of the Proteobacteria-affiliated clones identified in a 13,001 nearly full-length 16S rRNA gene clones 770 Van Vleet Oval 307 LSE derived from Oklahoma tall grass prairie soil.

Ehrlichiosis and Anaplasmosis Are Tick-Borne Diseases Caused by Obligate Anaplasmosis: Intracellular Bacteria in the Genera Ehrlichia and Anaplasma
Ehrlichiosis and Importance Ehrlichiosis and anaplasmosis are tick-borne diseases caused by obligate Anaplasmosis: intracellular bacteria in the genera Ehrlichia and Anaplasma. These organisms are widespread in nature; the reservoir hosts include numerous wild animals, as well as Zoonotic Species some domesticated species. For many years, Ehrlichia and Anaplasma species have been known to cause illness in pets and livestock. The consequences of exposure vary Canine Monocytic Ehrlichiosis, from asymptomatic infections to severe, potentially fatal illness. Some organisms Canine Hemorrhagic Fever, have also been recognized as human pathogens since the 1980s and 1990s. Tropical Canine Pancytopenia, Etiology Tracker Dog Disease, Ehrlichiosis and anaplasmosis are caused by members of the genera Ehrlichia Canine Tick Typhus, and Anaplasma, respectively. Both genera contain small, pleomorphic, Gram negative, Nairobi Bleeding Disorder, obligate intracellular organisms, and belong to the family Anaplasmataceae, order Canine Granulocytic Ehrlichiosis, Rickettsiales. They are classified as α-proteobacteria. A number of Ehrlichia and Canine Granulocytic Anaplasmosis, Anaplasma species affect animals. A limited number of these organisms have also Equine Granulocytic Ehrlichiosis, been identified in people. Equine Granulocytic Anaplasmosis, Recent changes in taxonomy can make the nomenclature of the Anaplasmataceae Tick-borne Fever, and their diseases somewhat confusing. At one time, ehrlichiosis was a group of Pasture Fever, diseases caused by organisms that mostly replicated in membrane-bound cytoplasmic Human Monocytic Ehrlichiosis, vacuoles of leukocytes, and belonged to the genus Ehrlichia, tribe Ehrlichieae and Human Granulocytic Anaplasmosis, family Rickettsiaceae. The names of the diseases were often based on the host Human Granulocytic Ehrlichiosis, species, together with type of leukocyte most often infected. -

Wolbachia, which are found in a variety of invertebrate species, are of great interest due to their diverse interactions with different hosts, which range from many forms of reproductive parasitism to mutualistic symbioses. Analysis of the wMel genome, in particular phylogenomic comparisons with other intracellular bacteria, has revealed many insights into the biology and evolution of wMel and Wolbachia in general. For example, the wMel genome is unique among sequenced obligate intracellular species in both being highly streamlined and containing very high levels of repetitive DNA and mobile DNA elements. -

ABSTRACT Ocean acidification significantly affects marine organisms in several ways, with complex interactions. Seaweeds might benefit from rising CO2 through increased photosynthesis and carbon acquisition, with subsequent higher growth rates. However, changes in seaweed chemistry due to increased CO2 may change the nutritional quality of tissue for grazers. In addition, organisms live in close association with a diverse microbiota, which can also be influenced by environmental changes, with feedback effects. As gut microbiomes are often linked to diet, changes in seaweed characteristics and associated microbiome can affect the gut microbiome of the grazer, with possible fitness consequences. In this study, we experimentally investigated the effects of acidification on the microbiome of the invasive brown seaweed Sargassum muticum and a native isopod consumer Synisoma nadejda. Both were exposed to ambient CO2 conditions Submitted 13 September 2017 (380 ppm, pH 8.16) and an acidification treatment (1,000 ppm, pH 7.86) for three Accepted 26 January 2018 weeks. -
Legionella Shows a Diverse Secondary Metabolism Dependent on a Broad Spectrum Sfp-Type Phosphopantetheinyl Transferase

Studies frequently focus on the abundant number of virulence factors present in this genus. However, what is often overlooked is the role of secondary metabolites from Legionella. Following whole genome sequencing, we assembled and annotated the Legionella parisiensis DSM 19216 genome. Together with 14 other members of the Legionella, we performed comparative genomics and analysed the secondary metabolite potential of each strain. We found that Legionella contains a huge variety of biosynthetic gene clusters (BGCs) that are potentially making a significant number of novel natural products with undefined function. Surprisingly, only a single Sfp-like phosphopantetheinyl transferase is found in all Legionella strains analyzed that might be responsible for the activation of all carrier proteins in primary (fatty acid biosynthesis) and secondary metabolism (polyketide and non-ribosomal peptide synthesis). Using conserved active site motifs, we predict Submitted 29 June 2016 some novel compounds that are probably involved in cell-cell communication, Accepted 25 October 2016 Published 24 November 2016 differing to known communication systems. -
