Metabolic pathways usually are common between archaea and bacteria. Diazotrophs are categorized into two main groups namely: root- nodule bacteria and plant growth-promoting rhizobacteria. Diazotrophs include free living bacteria, such as Azospirillum , Cupriavidus , and some sulfate reducing bacteria, and symbiotic diazotrophs such Rhizobium and Frankia . Three types of nitrogenase are iron and molybdenum (Fe/Mo), iron and vanadium (Fe/V) or iron only (Fe). The Mo-nitrogenase have a higher specific activity which is expressed better when Molybdenum is available. The best hosts for Rhizobium legumiosarum are Pisum , Vicia , Lathyrus and Lens ; Trifolium for Rhizobium trifolii ; Phaseolus vulgaris , Prunus angustifolia for Rhizobium phaseoli ; Medicago, Melilotus and Trigonella for Rhizobium meliloti ; Lupinus and Ornithopus for Lupini, and Glycine max for Rhizobium japonicum . Termites have significant key role in soil ecology, transporting and mixing soil. Termite gut microbes supply the enzymes required to degrade plant polymers, synthesize amino acids, recycle nitrogenous waste and fix atmospheric nitrogen. -
Comparative Genomic Analysis of Three Pseudomonas

Martin Luther King Jr. Blvd., Suite 305B, FSH Science Research Center, Florida A&M University, Tallahassee, FL 32307, USA; [email protected] 2 Department of Agricultural, Food and Nutritional Science, University of Alberta, Edmonton, AB T6G2P5, Canada; [email protected] * Correspondence: [email protected]; Tel.: +1-850-412-5119; Fax: +1-850-561-2248 Abstract: The eastern oysters serve as important keystone species in the United States, especially in the Gulf of Mexico estuarine waters, and at the same time, provide unparalleled economic, ecological, environmental, and cultural services. One ecosystem service that has garnered recent attention is the ability of oysters to sequester impurities and nutrients, such as nitrogen (N), from the estuarine water that feeds them, via their exceptional filtration mechanism coupled with microbially-mediated denitrification processes. It is the oyster-associated microbiomes that essentially provide these myriads of ecological functions, yet not much is known on these microbiota at the genomic scale, especially from warm temperate and tropical water habitats. Among the suite of bacterial genera that appear to interplay with the oyster host species, pseudomonads deserve further assessment because Citation: Pathak, A.; Stothard, P.; of their immense metabolic and ecological potential. To obtain a comprehensive understanding on Chauhan, A.

Performance Evaluation of Microbe and Plant-Mediated Processes in Phytoremediation of Toluene in Fractured Bedrock Using Hybrid Poplars
Performance evaluation of microbe and plant-mediated processes in phytoremediation of toluene in fractured bedrock using hybrid poplars by Michael Ben-Israel A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Environmental Sciences Guelph, Ontario, Canada © Michael Ben-Israel, March, 2020 ABSTRACT PERFORMANCE EVALUATION OF MICROBE AND PLANT-MEDIATED PROCESSES IN PHYTOREMEDIATION OF TOLUENE IN FRACTURED BEDROCK USING HYBRID POPLARS Michael Ben-Israel Advisor: University of Guelph, 2020 Dr. Kari Dunfield Efficacy of hybrid poplar trees for phytoremediation of toluene in fractured bedrock aquifers is unclear and active mechanisms require validation. This multi-year field study was conducted on a pilot phytoremediation system at an urban site, implemented to address aged toluene impacts to a shallow fractured dolostone aquifer. The study aimed to establish performance by quantifying phytoremedial activities at the site. Contaminant concentrations in groundwater, soil, and soil vapour, measured in high spatial resolution, showed the main residual toluene mass is coincident with the water table and located favourably for phyto-remedial uptake and biodegradation, with shallow groundwater concentrations approaching aqueous solubility in high-impact areas. Biodegradation occurring in the vadose zone was shown through metagenomic analyses that enumerated toluene degradation genes and gene transcripts in roots and root-associated soil, and compound-specific stable isotope analysis that showed enrichment of toluene stable carbon isotopes in soil vapour. Transpiration measurement, in planta contaminant quantification, and high-throughput sequencing of microbial taxonomic genes in roots and stem tissue were employed to measure toluene uptake through phytoextraction and resolve biodegradation influences upon uptake patterns. -

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. -

It is important to understand which are the major evolutionary groups and what are the genomic/proteomic components they have in common or are unique. Towards this goal, we analyzed 494 complete Pseudomonas proteomes and identified 297 core‐orthologues. The subsequent phylogenomic analysis revealed two well‐defined species (Pseudomonas aeruginosa and Pseudomonas chlororaphis) and four wider phylogenetic groups (Pseudomonas fluorescens, Pseudomonas stutzeri, Pseudomonas syringae, Pseudomonas putida) with a sufficient number of proteomes. As expected, the genus‐level core proteome was highly enriched for proteins involved in metabolism, translation, and transcription. In addition, between 39–70% of the core proteins in each group had a significant presence in each of all the other groups. Group‐specific core proteins were also identified, with P. -

Saline and Arid Soils: Impact on Bacteria, Plants, and Their Interaction

Michel 11, 15121 Alessandria, Italy; [email protected] (E.G.); [email protected] (G.L.) 2 Dipartimento di Scienze e Innovazione Tecnologica, Università del Piemonte Orientale, Piazza San Eusebio 5, 13100 Vercelli, Italy; [email protected] * Correspondence: [email protected] Received: 14 April 2020; Accepted: 29 May 2020; Published: 2 June 2020 Abstract: Salinity and drought are the most important abiotic stresses hampering crop growth and yield. It has been estimated that arid areas cover between 41% and 45% of the total Earth area worldwide. At the same time, the world’s population is going to soon reach 9 billion and the survival of this huge amount of people is dependent on agricultural products. Plants growing in saline/arid soil shows low germination rate, short roots, reduced shoot biomass, and serious impairment of photosynthetic efficiency, thus leading to a substantial loss of crop productivity, resulting in significant economic damage. However, plants should not be considered as single entities, but as a superorganism, or a holobiont, resulting from the intimate interactions occurring between the plant and the associated microbiota. Consequently, it is very complex to define how the plant responds to stress on the basis of the interaction with its associated plant growth-promoting bacteria (PGPB). This review provides an overview of the physiological mechanisms involved in plant survival in arid and saline soils and aims at describing the interactions occurring between plants and its bacteriome in such perturbed environments.
