Maintain at 15C. Temperature-sensitive unc-119 allele. Wild-type at 15C, intermediate Unc and Egl at 20C, and fully penetrant Unc and Egl at 25C. For use in transgenesis, maintain the strain at lower temperatures for increased brood size and easier injection, then transfer animals to 25C to select for transgenic animals based on Unc rescue. Molecular characterization shows a complex allele with a 210 bp duplication from a nearby exon-intron junction, which introduces 12 amino acids and a putative splice donor at a consensus splice acceptor site. The phenotype is most likely caused by temperature-sensitive splicing defects based on RT-PCR. Reference: Aljohani M, et al.

C. briggsae reference strain formerly known as PB420. Derived from C. briggsae Gujarat, the strain that later was named G16 and then AF16. PB420 was frozen (as C. briggsae Gujarat) 22 March 1991, thawed 15 June 2020 and sent to the CGC 1 July 2020. It may be considered ancestral to AF16 and was renamed to distinguish it from AF16 strains that have been maintained in laboratory cultures. Reference: Fodor A, et al.
