Driving miRNA expression in the V6 lineage can repress egl-5 expression. A. The integrated egl-5 reporter gene bxIs13 is expressed in ray sublineages, male sex muscles, tail hypodermis, and PLM. B. A transgene containing the mir-56 gene under the control of the V6 lineage cis-regulatory element V6CRE blocks bxIs13 expression in the ray sublineages and PLM but not in sex muscles or tail hypodermis. C. Transgenes containing mir-56 and mir-247 under the control of V6CRE can block bxIs13 expression in the V6 lineage and also generate a ray-defective phenotype consistent with absence of chromosomal egl-5 gene expression. Transgenes designed to express three other mir genes did not. Expression data is given for three independently transformed lines. P values are for comparison to bxIs13.
