Heterozygotes are WT and segregate WT, RolUncs and dead eggs. Homozygous wDf1 embryos arrest uniformly as unenclosed balls of differentiated cells. wDf2 formerly called zen-1(w1). sc8 previously called rol-4(sc8).

Pick WT to maintain. Throws WT, Roller Uncs and dead eggs. wDf4 arrests as dead eggs with no gut. sc8 previously called rol-4(sc8).

Halicephalobus mephisto wild isolate. Grow at 37C: can survive higher temperatures than C. elegans. Useful model organism for studying heat tolerance; has expanded Hsp70 and AIG1 gene families. Has approximately 1.15% snp heterozygosity. Parthenogenetic reproduction so it cannot be out-crossed. References: Borgonie G, et al. Nature. 2011 Jun 2;474(7349):79-82. Weinstein DJ, et al. Nat Commun. 2019 Nov 21;10(1):5268.

Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and Dpy Stu homozygotes that are non-GFP. Homozygous hT2[bli-4 let-? qIs48] inviable.

Daf-c strongly but not completely suppressed; some dauers visible at 25C. sa935 alone is moderate Daf-d (dauer defective) in plate starvation assays, and resistant to exogenous dauer pheromone. sa935 confers strong suppression of daf-8 and daf-14, weak suppression of daf-1, -4, -7. scd-2(sa935) single mutant looks WT. snb-1(md247) hypomorph is an excellent balancer for scd-2; snb-1 is immediately neighboring. Maintain at 15 degrees.

Defecation motor program executed twice each cycle period. Hyperactive loopy movement. Previously called dec-8(sa200).

Nrf. sa366 previously called nrf-2.

Recessive Daf-c mutation that also causes Odr and Che defects. Maintain at 15C. [The mec-1 mutation present in the original isolates has been eliminated.] Previously known as daf-21.

Long defecation cycle period. Slightly slow growing and scrawny. Reduced brood size, especially at 25C. See also WBPaper00003693; previously called dec-4(sa73).
