||cha-1(m324) dpy-13(e184) ama-1(m118)/nT1 IV; +/nT1 V.
||Heterozygotes are WT and segregate WT, Vul and Lethals.
||lin-1(e1275) cha-1(p1152) IV.
||Temperature sensitive Multi-vulva. Slow growing. Unc-coils, jerky going backward. Small.
||cha-1(p1182) IV; ccIs55 V.
||ccIs55 [unc-54::lacZ + sup-7(st5)] V. Unc lethal at 25C. Difficult to score <25C.
||cha-1(p1182) IV; unc-68(r1162) ccIs55 V.
||ccIs55 [unc-54::lacZ + sup-7(st5)] V. Slow movement at 25C; might not curl like cha-1 typically does. Very slow movement at 20C. unc-68 channel null.
||cha-1(p1182) IV; ccIs55 V; jIs1.
||ccIs55 [unc-54::lacZ + sup-7(st5)] V. jIs1 [myo-3::GFP + rol-6(su1006)]. jIs1 likely maps to LGI, LGII, or LGX. Rollers; not all animals roll well.
||Structural gene for choline acetyltransferase (ChAT). Slow growing. Unc-coils, jerky going backward. Small. Resistant to aldicarb and trichlorfon. 99% reduced choline acetyltransferase. Complex complementation pattern with unc-17.
||Temperature sensitive. Unc-difficulty in crawling backwards. Behavior phenotype more pronounced at 25C than at 16C or 20C. Trichlorfon resistant. This strain replaced strain DH401 because Mike Nonet tested DH401 and found it didn't contain cha-1, but did have an unc-11 mutation (5/97).
||Mild (leaky) allele of cha-1. Has approximately 10% WT ChAT activity. Behaviorally normal-normal growth and development. Males mate. Sensitive to cholinesterase inhibitor aldicarb.
||cha-1(md39) cho-1(tm373) IV.
||Temperature-sensitive lethal. Maintain at 15C. At 16-20C: aldicarb-resistant, small, Unc-coily, slow-growing, slow pharyngeal pumping. At 25C: tight coils, virtually no movement, virtually no pumping, no growth, lethal. References: Rand JB. Genetics. 1989 May;122(1):73-80. Mullen GP, et al. Genetics. 2007 Sep;177(1):195-204.
||Temperature-sensitive lethal. Maintain at 15C. At 16-20C: aldicarb-resistant, small, Unc-coily, slow-growing, slow pharyngeal pumping. At 25C: tight coils, virtually no movement, virtually no pumping, no growth, no long-term survival. The animals rapidly respond to temperature shift in either direction, even after more than an hour at the non-permissive temperature.

||cha-1(ok2253) IV/nT1 [qIs51] (IV;V).
||ZC416.8b. Homozygous lethal deletion chromosome balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok2253 homozygotes (probable early larval arrest). Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: GGACTGACACGCCAATTTTT. External right primer: TGCAATGGCCAAAATGACTA. Internal left primer: CGAGCTCATCGAAAACTTCC. Internal right primer: CCCAAGCCTAAGCCTAAACC. Internal WT amplicon: 2862 bp. Deletion size: 1712 bp. Deletion left flank: ACCGTATATCTACAGTACCCCTACATCACT. Deletion right flank: TGCAAAATATTTCTGTGAGAGGTAATTTAT.
