Heterozygotes segregate wild-type heterozygotes, Dpy, and sec-5 homozygotes (scrawny, small broods, abnormal gut appearance) sec-5 is homozygous maternal-effect lethal; M+Z- animals produce a few dead L1-L2 stage larvae with Vab defects. Based upon phenotype, pk2357 is a strong loss-of-function, but likely not a null allele; molecular lesion produces a premature stop at position 389. Reference: Frische EW, et al. EMBO J. 2007 Dec 12;26(24):5083-92. [NOTE: This strain was previously described as carrying pk2358, but pk2357 is the correct allele. Both pk2357 and pk2358 cause the same nonsense (amber) change.]

Bacteria. E. coli HT115(DE3) bacterial strain carrying pGC8. pGC8 is a partial cDNA of him-14 (ZK1127.11) cloned into the Timmons and Fire "double T-7 vector" L4440. The source of the cDNA is Yuji Kohara's clone yk240h12. pGC8 was constructed by inserting the 1.65kb KpnI/SacI fragment of the him-14 cDNA (from base pair 1071 to 192 base pairs beyond the stop codon) into the same sites in L4440. HT115(DE3) carrying pGC8 should be selected in the presence of 50 um/ml tetracyline and 100 um/ml ampicillin. Prior to an actual feeding experiment, it can be grown in liquid in the presence of amp alone (no tet) and then seeded onto NGM plates containing amp and 1 mM IPTG. This technique does not work well if the cells are old; therefore, the strain should be seeded onto IPTG-containing plates from a fresh overnight that was grown from a colony on an amp/tet plate. Biosafety Level: BSL-1. For more info see http://www.wormbook.org/wli/wbg17.1p32/

Heterozygotes are WT with GFP+ (pharynx) and segregate Dpy with GFP+ (pharynx) and slow growing GFP- animals which are generally sterile (with germline tumor at 25C). pro-1(na48) is a weak, recessive, loss-of-function allele that behaves as a stronger loss-of-function at lower temperatures. At 25C, 85% of na48 animals will develop a proximal germline tumorr. Although tumors are less common at lower temperatures, the animals are generally sterile due to low proliferation and somatic gonad defects. na48 animals are slow growing at all temperatures.

Heterozygotes are WT and GFP+, and segregate Sterile non-GFP (homozygous ar232) and dead eggs. ar232 have severely reduced germline proliferation.

At 20C and below, worms have smaller brood size than WT, although the gonad develops properly. At 25C, worms are sterile (either Glp or Pro). The animals grow slower than WT at all temperatures. Maintain at 20C or below.

At 20C and below, worms are visibly WT; animals grow somewhat larger than WT. At 25C, segregates WT, Glp and Pro. Maintain at 20C or below.
