TranscriptomicsL. lactis Î?lmrCD and cholate-adapted L. lactis Î?lmrCDR
Transcriptome profiling of a L. lactis strain lacking the MDR transporter genes lmrCD and the same strain adapted to cholate was performed. As compared to the parental strain, the cholate-adapted strain showed 124 genes that were significantly differentially expressed more than 1.8-fold . These gene...

TranscriptomicsTranscriptional changes associated to resistance to the cell wall active bacteriocin Lcn972
Lcn972 is a non-modified bacteriocin that targets exclusively Lactococcus sp. Addition of Lcn972 inhibits cell wall biosynthesis at the septum by binding to the cell wall precursor lipid II. Resistance to Lcn972 develops upon selection with subinhibitory concentrations. The transcriptome of the high...

TranscriptomicsDiscovering novel bile protection systems in Bifidobacterium breve UCC2003 through functional genomics
Tolerance of gut commensals to bile salt exposure is an important feature for their survival in and colonization of the intestinal environment. A transcriptomic approach was employed to study the response of Bifidobacterium breve UCC2003 to bile, allowing the identification of a number of bile-induc...

TranscriptomicspBL1 impairs cellobiose metabolism in Lactococcus lactis
pBL1 is a Lactococcus lactis theta-replicating 10.9-kbp plasmid that encodes the synthetic machinery of the bacteriocin Lcn972. In this work, the transcriptomes of exponentially growing L. lactis with and without pBL1 were compared. A discrete response was observed with a total of ten genes showing ...

TranscriptomicsSupervised Lowess normalization of comparative genome hybridization data: application to lactococcal strain comparisons.
Background Array-based comparative genome hybridization (aCGH) is commonly used to determine the genomic content of bacterial strains. In aCGH data, systematic errors are comparable to those occurring in transcriptome data. However, especially for microbes, an additional source of variation exists: ...

TranscriptomicsCcpA regulon in L. plantarum
This data set contains samples from Lactobacillus plantarum WCFS1 wild type and its CcpA mutant derivative. Both strains were grown in duplicate (samples L and R) and at four different growth stages samples were taken (early, mid and late log phase, early stationary phase). Samples were compared to ...

TranscriptomicsL. lactis NZ9000 (pNZbcaP-H6) Vs. L. lactis NZ9000 (pNZ8048)
Our transcriptome data shows that the two-component system CesSR, which senses cell envelope stresses of different origins, is one of the major players when L. lactis is forced to overproduce the endogenous membrane protein BcaP, a branched-chain amino acid permease. Two-condition experiment: nisin ...

TranscriptomicsSugar utilization in L. plantarum WCFS1
Lactobacillus plantarum was grown anaerobically on 4 different sugars (Mannose Lactose Fructose and Sucrose) to OD600 = 1.0. Samples were compared with a similar grown culture on glucose. An independnet biological duplicate of tht experimnet was performed (samples 1 and 2). L. plantarum WCFS1 grown ...

TranscriptomicsLytic infection of Lactococcus lactis by bacteriophages Tuc2009 and c2 trigger alternative transcriptional host responses
This study analysed the temporal transcriptional response of L. lactis UC509.9 undergoing infection with either Tuc2009 or c2, representing phages of two different species (P335 and c2, respectively) of the family Siphoviridae. For the first time, to our knowledge, both DNA microarrays of the host a...
