Abstract
Amino-acid starvation of a stringent strain of E. coli relieves the polar effect on distal messenger RNA imposed by a nonsense mutation. There is no relief of polarity starvation of a relaxed strain. In fact, starvation of a relaxed (but not of a stringent) strain by itself causes an artificial polar effect on distal mRNA. These findings are consistent with a mechanism for polarity based on mRNA degradation.
