Long. Unc. At 15C ar41 suppresses the 2 AC (anchor cell) phenotype of n676n930. (Strain GS878 does not contain sel(arX) and therefore does not suppress the Egl phenotype at 25C.) See also WBPaper00002966. Do not distribute this strain; other labs should request it from the CGC.

Temperature sensitive maternal effect lethal if shifted from 15C to 25C at the L4 and later stages; sterile if it gets past embryogenesis before being shifted. Maintain at 15C. MJ61 contains a lin-12 allele (ar170) which results in 2 anchor cells. GS1369 was derived by outcrossing MJ61 to remove ar170. Do not distribute this strain; other labs should request it from the CGC. Added 10/2005: Zhuoyu Ni in Sylvia Lee's lab did not find the published missense mutation in this strain. It does have the ts sterile/lethal phenotype still.

WT. Suppresses the egg-laying defect of lin-12(n302). Do not distribute this strain; other labs should request it from the CGC.

ar200 does not display any apparent phenotype. It suppresses the Egl defect of both sel-12(ar171) and sel-12(ar131), and displays genetic interactions with various lin-12 and glp-1 alleles. Do not distribute this strain; other labs should request it from the CGC.

Heterozygotes are wild-type and segregate wild-type heterozygotes, glp-1(q35) homozygotes (Muv steriles), eT1 homozygotes (Unc-36), and males. glp-1(q35) has a semi-dominant multi-vulva phenotype as well as the loss-of-function Glp phenotype (sterility and embryonic lethality). The q35 mutation is a nonsense mutation that eliminates 122 C-terminal amino acids including a PEST sequence. The C terminus was thought to contain a negative regulatory domain that inactivates glp-1 in the VPCs; the inappropriate glp-1(q35) activity can substitute for lin-12 vulval fate determination.
