Fig 1. Viability assay in wild-type C. elegans treated with nourseothricin.

(A) The effectiveness of nourseothricin on wild-type worms was divided into 3 classes. Absent or small: The effect was absent or slightly small during larvae development or in adult worm maintenance. Some: some larvae had arrested growth at the L1/ L2 stage, others developed to adulthood, but the adult worms died earlier than the controls but laid sufficient numbers of eggs. Strong: larval development stopped completely at the L1/L2 stage, or almost all the adults died a few days after adding the NTC solutions. The black frame indicates the optimal concentration of NTC. (B) Micrographs showing larvae and adult plates at the optimal concentration (0.04 mg/mL). Both pictures were taken four days after worm placement.
