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.

Received: 27 November 2019; Accepted: 9 January 2020; Published: 10 January 2020 Abstract: Members of the Microvirga genus are metabolically versatile and widely distributed in Nature. However, knowledge of the bacteria that belong to this genus is currently limited to biochemical characteristics. Herein, a novel thermo-tolerant bacterium named Microvirga thermotolerans HR1 was isolated and identified. Based on the 16S rRNA gene sequence analysis, the strain HR1 belonged to the genus Microvirga and was highly similar to Microvirga sp. 17 mud 1-3. The strain could grow at temperatures ranging from 15 to 50 ◦C with a growth optimum at 40 ◦C. It exhibited tolerance to pH range of 6.0–8.0 and salt concentrations up to 0.5% (w/v). It contained ubiquinone 10 as the predominant quinone and added group 8 as the main fatty acids. -

A Primary Assessment of the Endophytic Bacterial Community in a Xerophilous Moss (Grimmia Montana) Using Molecular Method and Cultivated Isolates
Brazilian Journal of Microbiology 45, 1, 163-173 (2014) Copyright © 2014, Sociedade Brasileira de Microbiologia ISSN 1678-4405 www.sbmicrobiologia.org.br Research Paper A primary assessment of the endophytic bacterial community in a xerophilous moss (Grimmia montana) using molecular method and cultivated isolates Xiao Lei Liu, Su Lin Liu, Min Liu, Bi He Kong, Lei Liu, Yan Hong Li College of Life Science, Capital Normal University, Haidian District, Beijing, China. Submitted: December 27, 2012; Approved: April 1, 2013. Abstract Investigating the endophytic bacterial community in special moss species is fundamental to under- standing the microbial-plant interactions and discovering the bacteria with stresses tolerance. Thus, the community structure of endophytic bacteria in the xerophilous moss Grimmia montana were esti- mated using a 16S rDNA library and traditional cultivation methods. In total, 212 sequences derived from the 16S rDNA library were used to assess the bacterial diversity. Sequence alignment showed that the endophytes were assigned to 54 genera in 4 phyla (Proteobacteria, Firmicutes, Actinobacteria and Cytophaga/Flexibacter/Bacteroids). Of them, the dominant phyla were Proteobacteria (45.9%) and Firmicutes (27.6%), the most abundant genera included Acinetobacter, Aeromonas, Enterobacter, Leclercia, Microvirga, Pseudomonas, Rhizobium, Planococcus, Paenisporosarcina and Planomicrobium. In addition, a total of 14 species belonging to 8 genera in 3 phyla (Proteo- bacteria, Firmicutes, Actinobacteria) were isolated, Curtobacterium, Massilia, Pseudomonas and Sphingomonas were the dominant genera. Although some of the genera isolated were inconsistent with those detected by molecular method, both of two methods proved that many different endophytic bacteria coexist in G. montana. According to the potential functional analyses of these bacteria, some species are known to have possible beneficial effects on hosts, but whether this is the case in G. -
Complete Genome Sequence of the Nitrogen-Fixing Bacterium Azospirillum Humicireducens Type Strain Sgz-5T
Yu et al. Standards in Genomic Sciences (2018) 13:28 https://doi.org/10.1186/s40793-018-0322-2 SHORT GENOME REPORT Open Access Complete genome sequence of the nitrogen-fixing bacterium Azospirillum humicireducens type strain SgZ-5T Zhen Yu1, Guiqin Yang1, Xiaoming Liu1, Yueqiang Wang1, Li Zhuang2* and Shungui Zhou3 Abstract The Azospirillum humicireducens strain SgZ-5T, belonging to the Order Rhodospirillales and the Family Rhodospirillaceae, was isolated from a microbial fuel cell inoculated with paddy soil. A previous work has shown that strain SgZ-5T was able to fix atmospheric nitrogen involved in plant growth promotion. Here we present the complete genome of A. humicireducens SgZ-5T, which consists of a circular chromosome and six plasmids with the total genome size of 6,834,379 bp and the average GC content of 67.55%. Genome annotations predicted 5969 protein coding and 85 RNA genes including 14 rRNA and 67 tRNA genes. By genomic analysis, we identified a complete set of genes that is potentially involved in nitrogen fixation and its regulation. This genome also harbors numerous genes that are likely responsible for phytohormones production. We anticipate that the A. humicireducens SgZ-5T genome will contribute insights into plant growth promoting properties of Azospirillum strains. Keywords: Azospirillum humicireducens, Complete genome, Nitrogen fixation, PGPP Introduction report [11], the nitrogen-fixing capability of strain Bacteria that live in the plant rhizosphere and possess a SgZ-5T was confirmed by acetylene-reduction assay and large array of potential mechanisms to enhance plant identification of a nifH gene. Furthermore, this strain growth are considered as PGPR [1–3]. -

Td3 is a Sesbania plant growth promoting, Cajanus cajan nodulating rhizobia. Studying its whole Rhizobia genome was important as it is a potent phosphate solubilizer with constitutive gluconic acid production ability P solubilization through operation of the periplasmic glucose oxidation pathway even under conditions of catabolite repression. Gluconic acid This is in contrast to the other explored phosphate solubilizers. Rhizobial isolates sequenced so far are known to Plant growth promotion lack components of the direct glucose oxidation pathway and cannot produce gluconic acid on its own. Here, we present the genome sequence of Rhizobium sp. Td3. Genome comprises of a single chromosome of size 5,606,547 bp (5.6 Mb) with no symbiotic plasmid. Rhizobium leguminosarum bv. viciae USDA2370 was the closest whole genome known. 109 genes responsible for diverse plant growth promoting activities like P solubilization, synthesis of acetoin, nitric oxide, indole-3 acetic acid, exopolysaccharide, siderophore and trehalose have been identified. Flagellar proteins, genes encoding antibiotic and metal resistance, enzymes required for combating oxidative stress as well as attachment and colonization in the plant rhizosphere are also present. Availability of genome sequence of such a versatile plant growth promoting agent will help in exploiting all the phyto-bene- ficial traits of Td3 for its use as a biofertilizer. -
