Using RIViT-seq technology, which combines an in vitro transcription assay with RNA sequencing, researchers identified the target genes of 11 sigma factors in Streptomyces coelicolor. The work, published in Nature Communications, was conducted by Joint Genome Institute (JGI) Director Nigel Mouncey and research scientist Hiroshi Otani. Both are members of the JGI’s Secondary Metabolite Science Program, which Mouncey leads. Transcription factors control when and how genes are turned on or off, making transcriptional regulation critical as it ensures those genes vital for growth and survival across various environments are expressed when their functions are needed.
