Filamentous phage IKe mRNAs conserve form and function despite divergence in regulatory elements.

Abstract excerpt

As a means of determining whether there has been selection to conserve the basic pattern of filamentous phage mRNAs, the major mRNAs representing genes II to VIII have been defined for a phage distantly related to the Ff group specific for Escherichia coli hosts bearing F pili. Phage IKe has a genome with 55% identity with the Ff genome and infects E. coli strains bearing N pili. The results reveal a remarkably...
