We have constructed a conceptual model of biogeochemical cycles and metabolic and microbial community shifts within a hot spring ecosystem via coordinated analysis of the "Bison Pool" (BP) Environmental Genome and a complementary contextual geochemical dataset of ~75 geochemical parameters. 2,321 16S rRNA clones and 470 megabases of environmental sequence(More)

Abstract OP9 is a yet-uncultivated bacterial lineage found in geothermal systems, petroleum reservoirs, anaerobic digesters, and wastewater treatment facilities. Here we use single-cell and metagenome sequencing to obtain two distinct,(More)
OP9 is a yet-uncultivated bacterial lineage found in geothermal systems, petroleum reservoirs, anaerobic digesters and wastewater treatment facilities. Here we use single-cell and metagenome sequencing to obtain two distinct, nearly complete OP9 genomes, one constructed from single cells sorted from hot spring sediments and the other derived from binned(More)
Attempts to classify living organisms by their physical characteristics are as old as biology itself. The advent of protein and DNA sequencing--most notably the use of 16S ribosomal RNA--defined a new level of classification that now forms our basic understanding of the history of life on earth. High-throughput sequencing currently provides DNA sequences at(More)
Despite the fact that heliobacteria are the only phototrophic representatives of the bacterial phylum Firmicutes, genomic analyses of these organisms have yet to be reported. Here we describe the complete sequence and analysis of the genome of Heliobacterium modesticaldum, a thermophilic species belonging to this unique group of phototrophs. The genome is a(More)
BACKGROUND Rhodospirillum centenum is a photosynthetic non-sulfur purple bacterium that favors growth in an anoxygenic, photosynthetic N2-fixing environment. It is emerging as a genetically amenable model organism for molecular genetic analysis of cyst formation, photosynthesis, phototaxis, and cellular development. Here, we present an analysis of the(More)
Joinvilleaceae is a family of tropical grass-like monocots that comprises only the genus Joinvillea. Previous studies have placed Joinvilleaceae in close phylogenetic proximity to the well-studied grass family. A full plastome sequence was determined and characterized for J. ascendens. The plastome was sequenced with next generation methods, fully assembled(More)
OP9 is a yet-uncultivated bacterial lineage found in geothermal systems, petroleum reservoirs, anaerobic digesters, and wastewater treatment facilities. Here we use single-cell and metagenome sequencing to obtain two distinct, nearly-complete OP9 genomes, one constructed from single cells sorted from hot spring sediments and the other derived from binned(More)
Metabolic flexibility revealed in the genome of the cyst-forming α-1 proteobacterium Rhodospirillum centenum. Abstract Background: Rhodospirillum centenum is a photosynthetic non-sulfur purple bacterium that favors growth in an anoxygenic, photosynthetic N 2-fixing environment. It is emerging as a genetically amenable model organism for molecular genetic(More)
