Figure 7. Uaa incorporation increases over multiple generations and is reversible.
(A) LWA1852 animals show an increase in OmeY-dependent luciferase activity over 3 generations compared to 1. (B) LWA1031 animals show an increase in Ala-DanAla-dependent luciferase activity over 3 generations compared to 1. For (A) and (B), animals were grown in duplicate on solid plates of indicated Uaa concentrations at 15 °C, and assayed after 1 or 3 generations' exposure to Uaa. (C) Comparison of multi-generation data and reversibility of Uaa incorporation. LWA1852 animals were grown in duplicate at 15 °C with 2 mM OmeY on solid plates for indicated generations. Removal of worms from the Uaa for 1 generation dropped the luciferase activity to baseline levels. All error bars represent s.e.m.; n ≥ 2.
