Figure 2From: Stable expression plasmids for Streptomyces based on a toxin-antitoxin systemTemperature effect in the growth of the different Strains. Growth of the host strain (S. lividans ΔTA-pKC796-Tox(pGM160- YefMslTS)) at 28°C (A) and at 37°C (B). Loss of the temperature-sensitive plasmid pGM160-YefMslTS originated a lethal strain. Strains S. lividans ΔTA-pKC796( pGM160- YefMslTS) and S. lividans ΔTA-pKC796-TA( pGM160- YefMslTS) were used as controls.Back to article page
