Project description:Bacteria belonging to phylum Gemmatimonadetes are found in a wide variety of environments and are particularly abundant in soils. To date, only two Gemmatimonadetes strains have been characterized. Here we report the complete genome sequence and methylation pattern of Gemmatirosa kalamazoonensis KBS708 (ATCC BAA-2150; NCCB 100411), the first characterized Gemmatimondetes strain isolated from soil. Examination of the methylome of Gemmatirosa kalamazoonenis KBS708 using kinetic data from single-molecule, real-time (SMRT) sequencing on the PacBio RS

Project description:Gemmatimonas phototrophica is the only phototrophic member of the recently discovered bacterial phylum Gemmatimonadetes. It was isolated from a freshwater lake in the Gobi desert and first described in 2014. So far, Gemmatimonas phototrophica is the only bacterium to have received a complete set of photosynthesis-related genes by horizontal gene transfer from an ancient phototrophic species from the phylum Proteobacteria. This organism illustrates the possibility for engineering phototrophic capability in a non-phototrophic organism and is therefore of great interest to the field of synthetic biology. The structure of the photosynthetic reaction center-light harvesting 1 complex is under investigation by cryo-EM. Proteomic analysis verified the identities of the expected protein components of this complex and, additionally revealed polypeptides that were previously undiscovered and could be mapped to the cryo-EM images.
Project description:Nanosynbacter lyticus type strain TM7x was the first cultivated member of the broadly prevelent, but poorly udnerstood Candidate Phylum Radiation super-phylum. TM7x was shown to be an obligate epibiont with a host range including Schaalia odontolyticus strain XH001. The process of infecting a naive host goes through multiple phases, from an initial binding and interaction phase we call the initial encounter, to a rapid die off of infected host cells, killing phase, followed by regrowth of the host cells, regrowth phase, and finally a stable symbiosis between the species, stable symbiosis.To obtain a better understanding of the process by which these species establish a stable symbiosis, we measured the transcriptome using RNA sequencing across the course of infection. We sampled infected host, XH001/TM7x, during the initial interaction, regrowth, and after attaining stable symbiosis, as well as naive host controls grown under the same culture conditions.
