Abstrakt: •We screened for new X-linked lethal mutations in the germ lines of male flies.•The flies carried mutant alleles of genes involved in transposon regulation.•Mutant ago3alleles did not affect the germ-line mutation rate.•Mutant piwiand Su(var)205(HP1) alleles tripled the germ-line mutation rate.•Depletion of chromatin-organizing proteins Piwi or HP1 may de-repress transposons.
