Transposition of copia-like nomadic elements can be induced by heat shock

Four males of an isogenic gt w super(a) Drosophila) line were heat shocked and then crossed with isogenic untreated females. The genomic distributions of the elements of five copia-like families were analyzed in the four F sub(1) flies by the Southern technique and compared with those in the untreat...

Description
Summary:Four males of an isogenic gt w super(a) Drosophila) line were heat shocked and then crossed with isogenic untreated females. The genomic distributions of the elements of five copia-like families were analyzed in the four F sub(1) flies by the Southern technique and compared with those in the untreated isogenic line. The pattern heterogeneity observed in the F sub(1) samples shows that extensive rearrangements can be induced by heat shock.
