Temperature sensitive defect in germ-line proliferation during larval development. Defect can be reversed by shifting worms from restrictive (25C) to permissive temperature (16C). Germ-line proliferation defect at restrictive temperature may be due to arrest in mitotic prophase. This strain is very useful for producing large populations of worms that essentially lack a germ line.

feIs5 [sur-5p::luciferase::GFP + rol-6(su1006)] X. Temperature-sensitive sterile. Maintain at 15C. Rollers. Strain is bioluminescent when provided with exogenous D-luciferin (potassium salt) due to sur-5 promoter driving expression of firefly (Photinus pyralis) luciferase (lacking the peroxisome tagging signal) fused in-frame to GFP(S65C). Pick animals with high levels of fluorescence to retain expression of luciferase transgene. This strain is for academic use only. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects. References: Lagido C, et al. BMC Physiol. 2008 Apr 2;8:7. McLaggan D, et al. PLoS One. 2012;7(10):e46503.
