Genomic Insight Into the Host–Endosymbiont Relationship of Endozoicomonas Montiporae CL-33T with Its Coral Host
ORIGINAL RESEARCH published: 08 March 2016 doi: 10.3389/fmicb.2016.00251 Genomic Insight into the Host–Endosymbiont Relationship of Endozoicomonas montiporae CL-33T with its Coral Host Jiun-Yan Ding 1, Jia-Ho Shiu 1, Wen-Ming Chen 2, Yin-Ru Chiang 1 and Sen-Lin Tang 1* 1 Biodiversity Research Center, Academia Sinica, Taipei, Taiwan, 2 Department of Seafood Science, Laboratory of Microbiology, National Kaohsiung Marine University, Kaohsiung, Taiwan The bacterial genus Endozoicomonas was commonly detected in healthy corals in many coral-associated bacteria studies in the past decade. Although, it is likely to be a core member of coral microbiota, little is known about its ecological roles. To decipher potential interactions between bacteria and their coral hosts, we sequenced and investigated the first culturable endozoicomonal bacterium from coral, the E. montiporae CL-33T. Its genome had potential sign of ongoing genome erosion and gene exchange with its Edited by: Rekha Seshadri, host.

Oil Type and Temperature Dependent Biodegradation Dynamics
Ribicic et al. BMC Microbiology (2018) 18:83 https://doi.org/10.1186/s12866-018-1221-9 RESEARCH ARTICLE Open Access Oil type and temperature dependent biodegradation dynamics - Combining chemical and microbial community data through multivariate analysis Deni Ribicic1,2* , Kelly Marie McFarlin1, Roman Netzer1, Odd Gunnar Brakstad1, Anika Winkler3, Mimmi Throne-Holst1 and Trond Røvik Størseth1 Abstract Background: This study investigates a comparative multivariate approach for studying the biodegradation of chemically dispersed oil. The rationale for this approach lies in the inherent complexity of the data and challenges associated with comparing multiple experiments with inconsistent sampling points, with respect to inferring correlations and visualizing multiple datasets with numerous variables. We aim to identify novel correlations among microbial community composition, the chemical change of individual petroleum hydrocarbons, oil type and temperature by creating modelled datasets from inconsistent sampling time points. Four different incubation experiments were conducted with freshly collected Norwegian seawater and either Grane and Troll oil dispersed with Corexit 9500. Incubations were conducted at two different temperatures (5 °C and 13 °C) over a period of 64 days. Results: PCA analysis of modelled chemical datasets and calculated half-lives revealed differences in the biodegradation of individual hydrocarbons among temperatures and oil types. At 5 °C, most n-alkanes biodegraded faster in heavy Grane oil compared to light Troll oil. PCA analysis of modelled microbial community datasets reveal differences between temperature and oil type, especially at low temperature. For both oils, Colwelliaceae and Oceanospirillaceae were more prominent in the colder incubation (5 °C) than the warmer (13 °C). Overall, Colwelliaceae, Oceanospirillaceae, Flavobacteriaceae, Rhodobacteraceae, Alteromonadaceae and Piscirickettsiaceae consistently dominated the microbial community at both temperatures and in both oil types. -

Editor: Julian Marchesi ABSTRACT In this paper, we describe the microbial composition and their predictive metabolic profile in the sea urchin Lytechinus variegatus gut ecosystem along with samples from its habitat by using NextGen amplicon sequencing and downstream bioinformatics analyses. The microbial communities of the gut tissue revealed a near-exclusive abundance of Campylobacteraceae, whereas the pharynx tissue consisted of Tenericutes, followed by Gamma-, Alpha- and Epsilonproteobacteria at approximately equal capacities. -

CHARACTERIZATION OF ORGANISMS IN VOSTOK (ANTARCTICA) GLACIAL, BASAL, AND ACCRETION ICE Colby J. Gura A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE December 2019 Committee: Scott O. Rogers, Advisor Helen Michaels Paul Morris © 2019 Colby Gura All Rights Reserved iii ABSTRACT Scott O. Rogers, Advisor Chapter 1: Lake Vostok is named for the nearby Vostok Station located at 78°28’S, 106°48’E and at an elevation of 3,488 m. The lake is covered by a glacier that is approximately 4 km thick and comprised of 4 different types of ice: meteoric, basal, type 1 accretion ice, and type 2 accretion ice. Six samples were derived from the glacial, basal, and accretion ice of the 5G ice core (depths of 2,149 m; 3,501 m; 3,520 m; 3,540 m; 3,569 m; and 3,585 m) and prepared through several processes. The RNA and DNA were extracted from ultracentrifugally concentrated meltwater samples. From the extracted RNA, cDNA was synthesized so the samples could be further manipulated. Both the cDNA and the DNA were amplified through polymerase chain reaction. Ion Torrent primers were attached to the DNA and cDNA and then prepared to be sequenced. Following sequencing the sequences were analyzed using BLAST. Python and Biopython were then used to collect more data and organize the data for manual curation and analysis. Chapter 2: As a result of the glacier and its geographic location, Lake Vostok is an extreme and unique environment that is often compared to Jupiter’s ice-covered moon, Europa. -
Horizontal Operon Transfer, Plasmids, and the Evolution of Photosynthesis in Rhodobacteraceae
The ISME Journal (2018) 12:1994–2010 https://doi.org/10.1038/s41396-018-0150-9 ARTICLE Horizontal operon transfer, plasmids, and the evolution of photosynthesis in Rhodobacteraceae 1 2 3 4 1 Henner Brinkmann ● Markus Göker ● Michal Koblížek ● Irene Wagner-Döbler ● Jörn Petersen Received: 30 January 2018 / Revised: 23 April 2018 / Accepted: 26 April 2018 / Published online: 24 May 2018 © The Author(s) 2018. This article is published with open access Abstract The capacity for anoxygenic photosynthesis is scattered throughout the phylogeny of the Proteobacteria. Their photosynthesis genes are typically located in a so-called photosynthesis gene cluster (PGC). It is unclear (i) whether phototrophy is an ancestral trait that was frequently lost or (ii) whether it was acquired later by horizontal gene transfer. We investigated the evolution of phototrophy in 105 genome-sequenced Rhodobacteraceae and provide the first unequivocal evidence for the horizontal transfer of the PGC. The 33 concatenated core genes of the PGC formed a robust phylogenetic tree and the comparison with single-gene trees demonstrated the dominance of joint evolution. The PGC tree is, however, largely incongruent with the species tree and at least seven transfers of the PGC are required to reconcile both phylogenies. 1234567890();,: 1234567890();,: The origin of a derived branch containing the PGC of the model organism Rhodobacter capsulatus correlates with a diagnostic gene replacement of pufC by pufX. The PGC is located on plasmids in six of the analyzed genomes and its DnaA- like replication module was discovered at a conserved central position of the PGC. A scenario of plasmid-borne horizontal transfer of the PGC and its reintegration into the chromosome could explain the current distribution of phototrophy in Rhodobacteraceae. -
