Allele-specific PCR reveals that CYP6D1 is on chromosome 1 in the house fly, Musca domestica.
A cytochrome P450, termed P450lpr, is the major P450 responsible for pyrethroid resistance in the Learn-PyR (LPR) strain of house fly. Recently, the putative gene (CYP6D1) coding for P450lpr has been sequenced from the LPR and aabys strains of house fly. Allele-specific polymerase chain reaction (ASPCR) was used for linkage group analysis with backcross progeny from the wild type LPR strain and a multiple marker strain (aabys). We found that CYP6D1 is linked to chromosome 1. The possible role of regulatory or modifying genes responsible for elevated P450lpr expression is discussed in relation to the chromosomal linkage of CYP6D1.
