Homozygous viable, gfp expression in intestine, hypodermis, somatic gonad, excretory duct, CAN neuron. Reference: Starich et al. eLife 2020;9:e58619. DOI: https://doi.org/10.7554/eLife.58619

Although this strain is maintainable as a homozygote it produces many dead embryos (~80%) and has a low viable brood size (~24 ± 18). Thus, the GFP tag compromises CYB-3 function.

Viable and fertile, grows and moves well. No apparent abnormalities yet noted. Reference: Spike CA, et al. Genetics. 2022 May 5;221(1):iyac051. doi: 10.1093/genetics/iyac051. PMID: 35377419

mTurqoise2 tag with linker sequence inserted into endogenous his-72 locus. mNeonGreen::2xFLAG tag inserted into endogenous yap-1 locus. Ubiquitous yellow fluorescence (488 nm or 514 nm) is cytosolic with modest nuclear signal and strong exclusion from nucleoli, but translocates to nuclei upon disruption of upstream Hippo pathway components.
