Semi-dominant. 60% of adult males will have protruding spicules; Prc (protraction constitutive) phenotype. Larval animals and adult hermaphrodites do not display any gross abnormal phenotypes. Prc males have a mating efficiency of 0. Non-Prc males have a mating efficiency of 3. Do not distribute this strain; other labs should request it from the CGC.

POPFOP(sy974) is the control plasmid with mutated binding sites. Analysis of POPFOP should always be used to subtract background expression. Do not distribute this strain; other labs should request it from the CGC.

syIs202 [vang-1::YFP + myo-2::DsRed + unc-119(+)]; outcrossing suggests array is integrated in LG V. Reference: Green JL, et al. Cell. 2008 Aug 22;134(4):646-56.

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.

syEx1147 [des-2::DES-2::GFP + pha-1(+) + pBluescript KS(+)]. Maintain at 25C to select for presence of transgene. GFP reporter is driven by the promoter of the des-2/des-3 operon and is expressed in ALA, RID, PVD, FLP, IL2, PLM, PVC, and M1 muscles of the pharynx. This construct contains 3.4 kb of sequence upstream of the des-2 start ATG (Treinin et al., 1998) (Van Buskirk and Sternberg, 2010).
