Tiling arrays and RNA-Seq alignment. Genome-wide transcription of the B. breve UCC2003 chromosome obtained using a combination of tiling array and RNA-Seq technologies. a Alignment of transcription patterns of B. breve genes (ORFs) as obtained from tiling array (blue) or RNA-Seq (red) data. Expression levels are indicated as RPKM (Reads Per Kilobase of transcript per Million mapped reads) in RNA-Seq dataset and FC (Fold-Change expressed as RNA signal strength vs gDNA baseline) in tiling arrays. b Genome-wide transcription of the B. breve UCC2003 chromosome as determined by a strand-specific tiling array (red for the forward and blue for the reverse strand) or RNA-Seq (grey)
