Description

A maternal germline specific promoter (bcd) drives expression of 4 x 2 modified forms of mir-6-1 that have been modified to target different sites in the O-fut1 5' untranslated region. This allele is used as a 'toxin' in the maternal-effect-lethal underdominance (UD[MEL]) system.

Comments

This construct is used as part of the maternal-effect-lethal underdominance (UD[MEL]) system. The U[DMEL] system utilizes two constructs, each consisting of a maternally expressed toxin and a zygotically expressed antidote. Each antidote is linked with a toxin whose activity it does not rescue (toxin A linked with antidote B and vice versa). As a result, the survival of embryos from mothers carrying one (UD[MEL-1]) or both (UD[MEL-1] and UD[MEL-2]) kinds of UD[MEL] chromosomes requires that they inherit the other (UD[MEL-2]) or both kinds of UD[MEL] chromosomes, respectively, in order to achieve zygotic rescue.
