Project description:Purpose -Comparison of proteome incubated in different media (rich and minimal media) -Three Xanthomonas species were used (Xanthomonas oryzae pv. oryaze, X. campestris pv. vesicatoria, and X. axonopodis pv. glycines. -Shotgun proteomic was used
Project description:Expression data for Desulfovibrio alaskensis strain G20 and mutants in regulator proteins grown on lactate sulfate media and then pelleted and transferred to another media when they reached stationary phase. The Choline mutant was transferred to lacte/sulfate minimal media and choline/sulfate minimal media. The LysX mutant was transferred to minimal media with lysine and rich media. G20 was transferred to minimal media, choline/sulfate minimal media, lactate/choline/sulfate minimal media, minimal media with lysine, and rich media. We aimed to confirm or expand the regulons of each of the transposon interupted regulator mutants and compare gene expression responses of the regulators in different growth conditions. 10 samples were collected: 2 regulator mutants (2 conditions each), Desulfovibrio alaskensis G20 (5 conditions), 2 replicates for G20 minimal media condition. Control sample -G20 rich media.
Project description:Enterohemorrhagic Escherichia coli (EHEC) are transmitted from cattle to human by means of contaminated food products resulting from fecal contamination. Transcriptome analysis was performed to gain further insight into the metabolic pathways required for persistence and growth of EHEC in the bovine intestine. Understanding the physiology of EHEC in the gut of ruminants is critical to identifying the potential nutritional basis to limiting EHEC shedding. A global transcriptome analysis was performed to gain further insight into the metabolic pathways required for persistence and growth of EHEC in the bovine intestine. DNA microarrays were performed using RNA from EHEC O157:H7 EDL933 incubated in bovine small intestine content (BSIC) compared with cells incubated in M9-minimal media. Four biological replicates collected for bacterial cultures on separate days for each media and labelled following a dye-switch design : For each media two replicates labeled in Cy3 and two replicates in Cy5.
Project description:Transcriptional profiling of Paracoccus denitrificans PD1222 wild type incubated in continuous culture (continuous culture (CSTR)) in minimal media with aerobic or anaerobic conditions. The goal was to define the core respiratory genes. Overall design: Two growth conditions, three biological replicates of each condition. Each sample hybridised in a two-channel hybridization against Paracoccus denitrificans genomic DNA as the comparator/reference, which also acted as a control for spot quality.
Project description:October 2010 surface seawater collected from Pacifica pier was incubated with 14 different substrates for 12 hours. Community RNA was extracted and hybridized to a Roche Nimblegen microarray and analyzed by NanoSIMS to obtain isotope ratio data for all probe spots. Overall design: Three Chips for fluorescence, and 14 Chips for different substrates from samples incubated for 12 hours.
Project description:Transcriptome of A. nidulans TNO2a3 and ∆ptpB strains when grown on minimal media plus casaminoacids and transferred to minimal media plus glucose as a sole carbon source for 4 hours Three conditions minimal media plus casaminoacids during 24 hours (reference) and minimal media plus glucose for 4 hours. Three strains TNO2a3 and ∆ptpB. Three biological repetitions of each timepoint of TNO2a3 / ∆ptpB
