Doc insertion in the second exon.
Mutation in sequenced strain: insertion of Doc transposon. This insertion is segregating in wild-type strains (see FBrf0188316).
Flies homozygous for the Doc{}CHKov1Doc1420 insertion show increased resistance to Sigma virus compared to control flies lacking the insertion, with infection rates dropping from 82% to 30%.
Flies carrying CHKov1Doc1420 have an increased resistance to organophosphates compared to controls.
