Defects in postembryonic M lineage: randomized cleavage orientations, reduced cell proliferation, cell fate transformation from CCs and BWMs to SMs. About 30% larval and adult lethality.

Defects in postembryonic M lineage: over-proliferation, cell fate transformation.

mNG tag inserted into endogenous mls-2 locus after the start codon using CRISPR/Cas9 engineering, producing a translational mNG::MLS-2 reporter protein. Derived by SEC excision of mls-2(vy247[mNG::SEC::mls-2 knock-in]) in parental strain. mNG::MLS-2 is detected in the nucleus of a few cells in embryos, and localizes to the nucleus of a subset of head cells and the M mesoblast in larvae and adults.

wgIs645 [mls-2::TY1::EGFP::3xFLAG + unc-119(+)]. TY1::EGFP::3xFLAG tag inserted in frame at C-terminus of coding sequence by recombineering. Expression of transgene confirmed by GFP.
