Wild isolate from Palm Canyon, CA. Segregated to remove gro-1(e2400) [CB4512]. Caenorhabditis elegans wild isolate CB gro-1(+) subclone of PaC1 (Tc1 pattern IV).

Slow growing. Homozygous gro-1(e2400) derived from PaC-1 (CB4507). Caenorhabditis elegans wild isolate CB subclone of PaC1 (Tc1 pattern IV?)].

Develops slowly (at the clk-3(qm38) rate). Segregates 1/4 Dpy. gro-1(e2400) is maternally rescued. clk-3; gro-1 doubles throw no Dpy and their progeny develop very slowly. To maintain strain pick WT worms singly onto plates and score progeny.

Slow growing. Not fertile at 25C. Daf-c at 27C.

Hets are WT and segregate WT, Dpys and maternally rescued GroClks (WT). To study gro-1 clk-2 doubles, pick WT worms singly onto plates. Maternally rescued gro-1 clk-2 worms segregate very slow hatching and developing progeny and no Dpys. Double mutants do not give a viable strain but rather die out after a few generations.
