lb130/+ dominantly suppresses the e15 backing defect and causes recessive sterility. Three phenotypes are present in this strain: backing steriles (lb130 homozygotes), backing fertiles which are bloated (heterozygotes), and non-backing coiled Unc animals which are fertile and bloated (sup-40(+)). Maintain strain by picking fertile animals which can back. egl-1(n487) is included in the strain to facilitate identification of lb130 homozygotes, which grow slowly; their sterility contrasts with the bloating of lb130/+ heterozygotes.

Egg-laying defective. Retains late stage eggs. Semi-dominant. Males mate successfully. Egg-laying serotinin sensitive and imipramine resistant.

n1165 blocks cell death. Temperature sensitive Egl. Semi-dominant Egl.

n4871 is a 1136 bp deletion that removes the last five exons, including the putative protease active site. Reference: Denning DP, et al. PLoS Genet. 2013;9(3):e1003341.

n4872 is a 722 bp deletion that removes part of exon 2 and all of exons 3 and 4. Reference: Denning DP, et al. PLoS Genet. 2013;9(3):e1003341.
