Rollers. Throws males. mgIs19 [lim-4::GFP + rol-6(su1006)].

syIs78 [ajm-1::GFP + unc-119(+)] is probably on LG I (not on II, III, V or X). Not sure if unc-119(ed4) from the parent strain is still present. Do not distribute this strain; other labs should request it from the CGC.

syIs197 [hs::LIN-3c(cDNA) + myo-2p::DsRed + pha-1(+)]. Him. Maintain at 15C. To induce LIN-3/EGF expression, heat shock at 33C for 30min (water bath) and let animals recover at least 1hr from the behavioral effects of the heat shock. Heat shock-induced LIN-3 should inhibit feeding, locomotion and sensory responses for several hours. For details on EGF-induced quiescence, see Nature Neuroscience 10, 1300 - 1307 (2007). PS5970 is identical to PS5628 as described in Development 137, 2065-2074 (2010) except that it has been outcrossed to remove accumulating suppressors.

This strain carries a knockout of the Nematode-Specific Peptide family, group F (NSPF) gene family, which localizes to sperm membranous organelles.

ncIs3 [pH20::GFP + pBlueScript]. Expresses GFP in nearly all neurons. No morphological or behavioral phenotypes.

Him. Temperature-sensitive sterile. Small brood size even at permissive temperatures; pick fertile animals and maintain at 15C. Worms lacking spe-45 function produce morphologically normal and motile sperm that cannot fuse with oocytes despite direct contact in the reproductive tract. spe-45 hermaphrodites and males are subfertile at 16C and sterile at 25C.
