Resistance began to increase between 1 1 2 and 3 h after inoculation under permissive conditions (wild-type strain at 20 °C or 30 °C, mutants at 20 °C), but failed to occur with the mutants under restrictive conditions (30 °C). These results imply that at 30 °C the RNA of the mutants fails to replicate in the initially infected cells. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-24-2-391
