Preparing cDNA Libraries from Lytic Phage-Infected Cells for Whole Transcriptome Analysis by RNA-Seq.

Whole genome wide analysis of transcription using RNA-Seq methods is a powerful way to elucidate differential expression of gene features in bacteria across different conditions as well as for discovering previously exotic RNA species. Indeed, RNA sequencing has revolutionized the study of bacterial transcription with the diversity and quantity of small noncoding RNA elements that have been found and its ability to clearly define operons, promoters , and terminators . We discuss our experience with applying RNA sequencing technology to analyzing the lytic cycle, including extraction, processing, and a guide to the customized statistical analysis necessary for analyzing differential host and phage transcription.
