GFP inserted into the endogenous vab-10a gene at its C-terminus by Cas9-triggered homologous recombination.

vab-10a(cas627 [vab-10a::TagBFP]) I.

Heterozygotes are WT and segregate WT, Uncs and dead eggs and larvae with severe body morphology defects that do not develop beyond the L2 stage. A few very rare mc44 larvae reach adulthood but they become sterile. mc 44 is a deletion affecting the downstream transcription unit of vab-10 named vab-10b. Fails to complement the vab-10 null reference allele vab-10(h1356), but complements the vab-10a alleles vab-10a(e698) and vab-10a(ju281).
