Project description:Differential RNA-Seq data for Vibrio campbellii BB120 (ATCC BAA-1116, previously designated as Vibrio harveyi)

Project description:Although many members of the genus Vibrio are known to inhabit the marine photic zone, an understanding of the influence of light on the molecular physiology of Vibrio spp. has largely been neglected. To begin to characterize the photophysiology of one such Vibrio sp. (Vibrio campbellii ATCC strain BAA-1116) we used microarray-based expression profiling to compare the transcriptomes of illuminated versus dark cell cultures. Specficially, we compared the transcriptomes of wild type V. campbellii (STR) cells that were cultured in M9 minimal salts medium plus glucose under two conditions: (i) after 24 hours of continuous dark and (ii) after a 12 hour dark:12 hour light cycle (white light illumination at 54 µmol photons s-1 m-2). The results revealed a large photostimulon (differential expression of ~20% of the V. campbellii genome; adjusted p value < 0.0001) that surprisingly included ~75% of the type III secretion system (T3SS) genes which were found to be 1.6 – 5.4X more abundant in illuminated cultures. These findings, which were confirmed by quantitative reverse transcription PCR and quantitative membrane proteomics, strongly suggest that the photostimulon of strain BAA-1116 includes the T3SS.

The results revealed a large photostimulon (differential expression of ~20% of the V. campbellii genome; adjusted p value < 0.0001) that surprisingly included ~75% of the type III secretion system (T3SS) genes which were found to be 1.6 M-bM-^@M-^S 5.4X more abundant in illuminated cultures. These findings, which were confirmed by quantitative reverse transcription PCR and quantitative membrane proteomics, strongly suggest that the photostimulon of strain BAA-1116 includes the T3SS. Five biological replicates of V. campbellii BAA-1116 (STR) were grown to log phase (200 rpm, 30M-BM-0C, 25 mL M9 minimal salts medium plus glucose in 125 mL baffled Erlenmeyer flasks) under continuous dark for 24 hours or under a 12 hour dark:12 hour light cycle (white light illumination at 54 M-BM-5mol photons s-1 m-2) and total RNA was extracted from 1.0E+9 cells. Messenger RNA was isolated from the total RNA extracts treated with DNase, labeled with biotin, fragmented and hybridized to V. campbellii BAA-1116 whole genome microarrays (520694F, Affymetrix).

Project description:Vibrio campbellii is a gram-negative bacterial pathogen that is both free-living and a pathogen of marine organisms and exhibits swimming motility via a single, polar flagellum. Swimming motility is a critical virulence factor in V. campbellii pathogenesis, and disruption of the flagellar motor significantly decreases host mortality. However, while V. campbelli encodes homologs of flagellar and chemotaxis genes conserved by other members of the Vibrionaceae, the regulatory network governing these genes have not been explored. We systematically deleted all 63 known flagellar and chemotaxis genes in V. campbellii and examined their effects on motility compared to their homologs in other Vibrios. We specifically focused on assessing the roles of the core flagellar regulators of the flagellar regulatory hierarchy established in other Vibrios: rpoN, flrA, flrC, and fliA. Although V. campbellii transcription of flagellar and chemotaxis genes is governed by a multi-tiered regulatory hierarchy similar to other Vibrios, we observed two critical differences: the σ54-dependent regulator FlrA is dispensable for motility, and Class II gene expression is independent of σ54 regulation. Our genetic and phenotypic dissection of the V. campbellii flagellar regulatory network highlights the differences that have evolved in flagellar regulation across the Vibrionaceae.
