An intact RNA interference pathway is required for expression of the mutant wing phenotype of vg(21-3), a P-element-induced allele of the vestigial gene in Drosophila
{{output}}
We have determined that two P elements, P[21-3] and P[21r36], residing in the 5'-UTR of the vestigial wing gene, encode functional repressors in eye tissue. However, neither element fits a previous categorization of repressor-making elements as Type I or II. B... ...
