The highly conserved Ubiquitin proteins are expressed from genes with strong, constitutively active promoters in many species, making these promoters attractive candidates for use in driving transgene expression. Here we report the cloning and characterization of the Tribolium castaneum Polyubiquitin ( TcPUb ) gene. We placed the TcPUb promoter upstream of the coding region of the T. castaneum eye‐colour gene Tc vermilion ( Tcv ) and injected this construct into embryos from a Tcv ‐deficient strain. Transient expression of Tcv during embryogenesis resulted in complete rescue of the larval mutant phenotype. We then incorporated the TcPUb‐Tcv chimera into a piggyBac donor. Resulting germline transformants were easily recognized by rescue of eye pigmentation, illustrating the potential of the TcPUb promoter for use in driving transgene expression.
