Homozygous viable. Modification of endogenous erm-1 locus mimics ERM-1(T544) phosphorylation. Variant affects ERM-1 localization and dynamics. Reduced brood size, increased embryonic and larval lethality. Reference: Ramalho JJ, et al. Development. 2020 Jul 22;147(14):dev188011. PMID: 32586975

Homozygous viable. Modification of endogenous erm-1 locus mimics non-phosphorylated ERM-1(T544). Variant affects ERM-1 localization and dynamics. Reduced brood size, increased embryonic and larval lethality. Reference: Ramalho JJ, et al. Development. 2020 Jul 22;147(14):dev188011. PMID: 32586975

Endogenous erm-1 locus tagged with eGFP. Homozygous viable, partially functional endogenous erm-1 tag. erm-1::GFP animals have a reduced brood size and incomplete outgrowth of the excretory canal, but show no other developmental or morphological abnormalities.

Homozygous viable. Endogenous erm-1 locus tagged with eGFP and modified to mimic ERM-1(T544) phosphorylation. Variant affects ERM-1 localization and dynamics. Reduced brood size, increased embryonic and larval lethality. eGFP-tagged ERM-1 is not fully functional: animals have a reduced brood size and incomplete outgrowth of the excretory canal, but show no other developmental or morphological abnormalities. The penetrance of intestinal phenotypes is slightly higher than in untagged T544 mutants, presumably owing to a detrimental influence of the COOH-terminal GFP tag. Reference: Ramalho JJ, et al.

Animals which have lost the Dp grow up to bagging adults with few progeny. Some of these hatch but die as L1s.

C01G8.5. Homozygous viable deletion chromosome balanced by lon-2-marked translocation. Heterozygotes are WT, and segregate WT, Lon-2 males, arrested szT1 aneuploids, and ok3268 homozygotes.
