FUNCTIONAL STUDIES on Csis and Csps
FUNCTIONAL STUDIES ON CSIs AND CSPs FUNCTIONAL SIGNIFICANCE OF NOVEL MOLECULAR MARKERS SPECIFIC FOR DEINOCOCCUS AND CHLAMYDIAE SPECIES BY F M NAZMUL HASSAN, B.Sc. A Thesis Submitted to the School of Graduate Studies in Partial Fulfillment of the Requirements for the Degree Master of Science McMaster University © Copyright by F M Nazmul Hassan, December, 2017 MASTER OF SCIENCE (2017) McMaster University (Biochemistry) Hamilton, Ontario TITLE: Functional Significance of Novel Molecular Markers Specific for Deinococcus and Chlamydiae Species AUTHOR: F M Nazmul Hassan, B.Sc. (Khulna University) SUPERVISOR: Professor Radhey S. Gupta NUMBER OF PAGES: xv, 108 ii This thesis is dedicated to my mom and dad. I lost my mother when I was a high school student. She always liked to share stories about science and inspired me to do something for the beneficial of human being. Her dream was guided by my father. I was always encouraged by my father to do higher education. I have lost my father this year. It was most critical moment of my life. But, I have continued to do research because of fulfill his dream. iii THESIS ABSTRACT The Deinococcus species are highly resistant to oxidation, desiccation, and radiation. Very few characteristics explain these unique features of Deinococcus species. This study reports the results of detailed comparative genomics, structural and protein-protein interactions studies on the DNA repair proteins from Deinococcus species. Comparative genomics studies have identified a large number of conserved signature indels (CSIs) in the DNA repair proteins that are specific for Deinococcus species. In parallel, I have carried out the structural and protein-protein interactions studies of CSIs which are present in nucleotide excision repair (NER), UV damage endonuclease (UvsE)-dependent excision repair (UVER) and homologous recombination (HR) pathways proteins. -

Global Metagenomic Survey Reveals a New Bacterial Candidate Phylum in Geothermal Springs
ARTICLE Received 13 Aug 2015 | Accepted 7 Dec 2015 | Published 27 Jan 2016 DOI: 10.1038/ncomms10476 OPEN Global metagenomic survey reveals a new bacterial candidate phylum in geothermal springs Emiley A.

Ivanova1 Analysis of the increasing wealth of metagenomic data collected from diverse environments can lead to the discovery of novel branches on the tree of life. Here we analyse 5.2 Tb of metagenomic data collected globally to discover a novel bacterial phylum (‘Candidatus Kryptonia’) found exclusively in high-temperature pH-neutral geothermal springs. This lineage had remained hidden as a taxonomic ‘blind spot’ because of mismatches in the primers commonly used for ribosomal gene surveys. Genome reconstruction from metagenomic data combined with single-cell genomics results in several high-quality genomes representing four genera from the new phylum. Metabolic reconstruction indicates a heterotrophic lifestyle with conspicuous nutritional deficiencies, suggesting the need for metabolic complementarity with other microbes. Co-occurrence patterns identifies a number of putative partners, including an uncultured Armatimonadetes lineage. The discovery of Kryptonia within previously studied geothermal springs underscores the importance of globally sampled metagenomic data in detection of microbial novelty, and highlights the extraordinary diversity of microbial life still awaiting discovery. 1 Department of Energy Joint Genome Institute, Walnut Creek, California 94598, USA. 2 Department of Biological Sciences, University of Calgary, Calgary, Alberta T2N 1N4, Canada. -
The Effects of Natural Variation in Background Radioactivity on Humans, Animals and Other Organisms
Biol. Rev. (2012), pp. 000–000. 1 doi: 10.1111/j.1469-185X.2012.00249.x The effects of natural variation in background radioactivity on humans, animals and other organisms Anders P. Møller1,∗ and Timothy A. Mousseau2 1Laboratoire d’Ecologie, Syst´ematique et Evolution, CNRS UMR 8079, Universit´e Paris-Sud, Bˆatiment 362, F-91405, Orsay Cedex, France 2Department of Biological Sciences, University of South Carolina, Columbia, SC 29208, USA ABSTRACT Natural levels of radioactivity on the Earth vary by more than a thousand-fold; this spatial heterogeneity may suffice to create heterogeneous effects on physiology, mutation and selection. We review the literature on the relationship between variation in natural levels of radioactivity and evolution. First, we consider the effects of natural levels of radiation on mutations, DNA repair and genetics. A total of 46 studies with 373 effect size estimates revealed a small, but highly significant mean effect that was independent of adjustment for publication bias. Second, we found different mean effect sizes when studies were based on broad categories like physiology, immunology and disease frequency; mean weighted effect sizes were larger for studies of plants than animals, and larger in studies conducted in areas with higher levels of radiation. Third, these negative effects of radiation on mutations, immunology and life history are inconsistent with a general role of hormetic positive effects of radiation on living organisms. Fourth, we reviewed studies of radiation resistance among taxa. These studies suggest that current levels of natural radioactivity may affect mutational input and thereby the genetic constitution and composition of natural populations. -

Horizontal Gene Transfer Elements: Plasmids in Antarctic Microorganisms
Chapter 5 Horizontal Gene Transfer Elements: Plasmids in Antarctic Microorganisms Matías Giménez, Gastón Azziz, Paul R. Gill, and Silvia Batista Abstract Plasmids play an important role in the evolution of microbial communi- ties. These mobile genetic elements can improve host survival and may also be involved in horizontal gene transfer (HGT) events between individuals. Diverse culture-dependent and culture-independent approaches have been used to character- ize these mobile elements. Culture-dependent methods are usually associated with classical microbiological techniques. In the second approach, development of spe- cific protocols for analysis of metagenomes involves many challenges, including assembly of sequences and availability of a reliable database, which are crucial. In addition, alternative strategies have been developed for the characterization of plas- mid DNA in a sample, generically referred to as plasmidome. The Antarctic continent has environments with diverse characteristics, including some with very low temperatures, humidity levels, and nutrients. The presence of microorganisms and genetic elements capable of being transferred horizontally has been confirmed in these environments, and it is generally accepted that some of these elements, such as plasmids, actively participate in adaptation mechanisms of host microorganisms. Information related to structure and function of HGT elements in Antarctic bac- teria is very limited compared to what is known about HGT in bacteria from temper- ate/tropical environments. Some studies are done with biotechnological objectives. The search for mobile elements, such as plasmids, may be related to improve the expression of heterologous genes in host organisms growing at very low tempera- tures. More recently, however, additional studies have been done to detect plasmids in isolates, associated or not with specific phenotypes such as drug resistance. -

This strain was resistant to UV irradiation (810 J m”2) and slightly more sensitive to desiccation as compared with Deinococcus radiodurans. Phylogenetic analyses based on the 16S rRNA gene sequence of the isolate indicated that the organism belongs to the genus Deinococcus. Highest sequence similarities were with Deinococcus ficus CC-FR2-10T (93.5 %), Deinococcus xinjiangensis X-82T (92.8 %), Deinococcus indicus Wt/1aT (92.5 %), Deinococcus daejeonensis MJ27T (92.3 %), Deinococcus wulumuqiensis R-12T (92.3 %), Deinococcus aquaticus PB314T (92.2 %) and T Deinococcus radiodurans DSM 20539 (92.2 %). Major fatty acids were C18 : 1v7c, summed feature 3 (C16 : 1v7c and/or C16 : 1v6c), anteiso-C15 : 0 and C16 : 0. The G+C content of the genomic DNA of strain G3-6-20T was 63.1 mol%. Menaquinone 8 (MK-8) was the predominant respiratory quinone. Based on its phylogenetic position, and chemotaxonomic and phenotypic characteristics, strain G3-6-20T represents a novel species of the genus Deinococcus, for which the name Deinococcus antarcticus sp. -
