New evidence for old detective work

Article Abstract:

A genetic selection procedure was utilized in an experiment conducted in 1982 to characterize the effects of tamA mutations in Aspergillus nidulans. The formation of a repressed phenotype due to tamA mutations in Aspergillus nidulans was mediated by glnA mutations which induced nitrogen metabolite derepression. Translation fusion reporter gene experiments that were conducted in 1985 and 1986 also supported the ability of tamA mutations to induce a partially-repressed phenotype.

Temporal transcription of the lactococcal temperate phage TP901-1 and DNA sequence of the early promoter region

Article Abstract:

The transcriptional pattern during the lytic growth of the temperate lactococcal bacteriophage TP901 was examined using hybridizing Northern blots of RNA from infected cells with various regions of the TP901 genome. Clusters of early, middle and late transcribed genes were identified and candidates for regions of gene regulation were determined. It was also shown that the region upstream of the integrase was transcribed early during the infection by TP901-1.
