  • Diversity of Bacteria and Archaea in the Deep-Sea Low-Temperature Hydrothermal Sulfide Chimney of the Northeastern Pacific Ocean

Accepted 4 November, 2011 Our knowledge of the diversity and role of hydrothermal vents microorganisms has considerably expanded over the past decade, while little is known about the diversity of microorganisms in low-temperature hydrothermal sulfide chimney. In this study, denaturing gradient gel electrophoresis (DGGE) and 16S rDNA sequencing were used to examine the abundance and diversity of microorganisms from the exterior to the interior of the deep sea low-temperature hydrothermal sulfide chimney of the Northeastern Pacific Ocean. DGGE profiles revealed that both bacteria and archaea could be examined in all three zones of the chimney wall and the compositions of microbial communities within different zones were vastly different. Overall, for archaea, cell abundance was greatest in the outermost zone of the chimney wall. For bacteria, there was no significant difference in cell abundance among three zones. In addition, phylogenetic analysis revealed that Verrucomicrobia and Deltaproteobacteria were the predominant bacterial members in exterior zone, beta Proteobacteria were the dominant members in middle zone, and Bacillus were the abundant microorganisms in interior zone.

  • Analysis of Tardigrade Damage Suppressor Protein (Dsup) Expressed in Tobacco
    Analysis of Tardigrade Damage Suppressor Protein (Dsup) Expressed in Tobacco by Justin Kirke A Thesis Submitted to the Faculty of The Charles E. Schmidt College of Science In Partial Fulfillment of the Requirements for the Degree of Master of Science Florida Atlantic University Boca Raton, FL December 2019 Copyright 2019 by Justin Kirke ii Abstract Author: Justin Kirke Title: Analysis of Tardigrade Damage Suppressor Protein (Dsup) Expressed in Tobacco Institution: Florida Atlantic University Thesis Advisor: Dr. Xing-Hai Zhang Degree: Master of Science Year: 2019 DNA damage is one of the most harmful stress inducers in living organisms. Studies have shown that exposure to high doses of various types of radiation cause DNA sequence changes (mutation) and disturb protein synthesis, hormone balance, leaf gas exchange and enzyme activity. Recent discovery of a protein called Damage Suppressor Protein (Dsup), found in the tardigrade species Ramazzotius varieornatus, has shown to reduce the effects of radiation damage in human cell lines. We have generated multiple lines of tobacco plants expressing the Dsup gene and preformed numerous tests to show viability and response of these transgenic plants when exposed to mutagenic chemicals, UV radiation and ionizing radiation. We have also investigated Dsup function in association to DNA damage and repair in plants by analyzing the expression of related genes using RT-qPCR. We have also analyzed DNA damage from X-ray and UV treatments using an Alkaline Comet Assay. This project has the potential to help generate plants that are tolerant to more extreme stress environments, particularly DNA damage and iv mutation, unshielded by our atmosphere.

The sediment was incubated together with a mix- ture of four electron donors and pentaCB, and after five months of incubation, the microbial community structure was analyzed. Both DGGE and clone library analyses showed that the most expansive phylogenetic group within the consortium was affiliated with the phylum Chloroflexi, which includes Dehalococcoides-like bacteria. PCR using a degenerate primer set targeting conserved regions in reductive-dehalogenase-homologous (rdh) genes from Dehalococcoides species revealed that DNA fragments (approximately 1.5–1.7 kb) of rdh genes were am- plified from genomic DNA of the consortium. The deduced amino acid sequences of the rdh genes shared sever- al characteristics of reductive dehalogenases.

  • Diapause in Tardigrades: a Study of Factors Involved in Encystment

Tardigrades represent one of the few animal phyla able to perform both forms of dormancy: quiescence and diapause. Different forms of cryptobiosis (quiescence) are widespread and well studied, while little attention has been devoted to the adaptive meaning of encystment (diapause). Our goal was to determine the environmental factors and token stimuli involved in the encystment process of tardigrades. The eutardigrade Amphibolus volubilis, a species able to produce two types of cyst (type 1 and type 2), was considered. Laboratory experiments and long-term studies on cyst dynamics of a natural population were conducted. Laboratory experiments demonstrated that active tardigrades collected in April produced mainly type 2 cysts, whereas animals collected in November produced mainly type 1 cysts, indicating that the different responses are functions of the physiological state at the time they were collected. The dynamics of the two types of cyst show opposite seasonal trends: type 2 cysts are present only during the warm season and type 1 cysts are present during the cold season.

  • A DNA Ligase from the Psychrophile Pseudoalteromonas Haloplanktis Gives Insights Into the Adaptation of Proteins to Low Temperatures
    Eur. J. Biochem. 267, 3502±3512 (2000) q FEBS 2000 A DNA ligase from the psychrophile Pseudoalteromonas haloplanktis gives insights into the adaptation of proteins to low temperatures D.

Protein sequence analysis revealed that the cold- adapted Ph DNA ligase shows a significant level of sequence similarity to other NAD1-dependent DNA ligases and contains several previously described sequence motifs. Also, a decreased level of arginine and proline residues in Ph DNA ligase could be involved in the cold-adaptation strategy. Moreover, 3D modelling of the N-terminal domain of Ph DNA ligase clearly indicates that this domain is destabilized compared with its thermophilic homologue. The recombinant Ph DNA ligase was overexpressed in Escherichia coli and purified to homogeneity. Mass spectroscopy experiments indicated that the purified enzyme is mainly in an adenylated form with a molecular mass of 74 593 Da. Ph DNA ligase shows similar overall catalytic properties to other NAD1-dependent DNA ligases but is a cold-adapted enzyme as its catalytic efficiency (kcat/Km) at low and moderate temperatures is higher than that of its mesophilic counterpart E.
