Project description:Global RNA half lives in cyanobacteria
| PRJNA429921 | ENA
Project description:We calculated global RNA half lives for all genes in the cyanobacteria Synechococcus sp. strain PCC 7002. Samples from three replicates of the WT strain were taken before and following the addition of the antibiotic rifampicin to stop nascent transcription. RNA spike-ins were added for normalization and using the number of RNA-sequencing reads we were able to calculate half lives for genes, transcripts, and for each position on the genome.

Project description:As an essential primary producer, cyanobacteria play an important role in the global cycle for both carbon and nitrogen in the ecosystems. Though the influence of nanoplastics on the carbon metabolism of cyanobacteria, especial Microcystis aeruginosa, a dominant species causing cyanobacterial blooms, is well studied, little is known about nanoplastics affecting the nitrogen metabolism.

Project description:Biological soil crusts (BSCs) are cyanobacteria-dominated microbial communities that cover extensive portions of the world’s arid and semi-arid deserts. The infrequent periods of hydration are often too short to allow for dormancy strategies based on sporulation; consequently, survival is based on the unique capabilities of vegetative cells to resuscitate from and re-enter a stress resistant dormant state, one of which is migration within the crust layers in response to hydration. In this study, we sought to characterize the events that govern the emergence of the dominant cyanobacterium from dormancy, its subsequent growth, and the events triggered by re-desiccation and a transition back to dormant state. We performed a 48 hour laboratory wetting experiment of a desert BSC and tracked the response of Microcoleus vaginatus using a whole genome transcriptional time-course including night/day periods. This allowed the identification of genes with a diel expression pattern, genes involved uniquely in the signaling after hydration and those that contribute primarily to desiccation preparation. Desert BSC samples collected from Moab, UT, were hydrated over a period of 48 hours followed by drying induced by removal of water. At periodic times soil samples were harvested and used for RNA extraction and whole genome expression analysis using an expression array representing genes from two strains of M. vaginatus (PCC 9802 and FGP-2)

Project description:In this study, we undertook a global proteomics analysis of isolated PSII complexes, comparing protein profiles of HT3 (C-terminal hexahistidine tagged CP47 protein) to those of deltaPsbV HT3, deltaPsbP HT3, and deltaPsbQ HT3. The sensitivity of these techniques allowed for identification of not only stoichiometric components of active PSII complexes, but also for the identification of proteins that are transiently associated with PSII throughout its lifecycle, such as assembly, repair, or degradation partners. From the results, we identified an operon of unknown function which contains binding domains for photosynthetic cofactors and which we have named the cofactor integration operon (cio). Upon deletion of the operon, photosynthetic capacity is decreased, indicating a function in PSII-mediated activity. Keywords: proteomic, photosystem II, cyanobacteria

Project description:Colorectal polypectomy is offten incompletely performed with high variability between endoscopists, resulting in interval cancer or repeated procedures. Current available scoring systems for polypectomy technique are lacking in different areas so the investigators developed the Global Polypectomy Assessment Tool (GPAT) which is an online video-based assessment tool for any colorectal polypectomy.
The goal of the study is to assess the validity of GPAT through demonstrating the inter-rater agreement (Fleiss Kappa (κ)). GPAT has 20 items, contains evidence-based statements to aid interpretation, calculates an overall quality score and a complexity score.
