Project description:We present transcriptomic analysis of an infection by a cluster A4 mycobacteriophage of its host, Mycobacterium smegmatis, at six time points (n = 2). Viral transcription is detectable 5 minutes into infection, and viral mRNA makes up the vast majority of all transcription by 30 minutes. Kampy, like many phages, has a genome organized into two arms bearing early- and late-phase genes. We identify two transcriptional start sites (TSS’s) consistent with an early promoter driving expression of half of the genome, along with a second, late-stage promoter that becomes active around 30 minutes after the start of infection.
Project description:Here, we describe LilHazelnut, a novel mycobacteriophage that infects Mycobacterium smegmatis mc2155. LilHazelnut is a cluster Q phage that shares 99% nucleotide identity with phage Giles, is 53,746 bp in length, and has a G+C content of 67.5%. LilHazelnut is a temperate Siphoviridae virus, as is typical of cluster Q family members.
