[High frequency induction of small mosaic cell clones in the Drosophila wings under the influence of gamma-irradiation].

As it was shown earlier in Gonzalez-Gaitan et al., one-cell and two-cells clones (tailing clones) are induced in the Drosophila wings after irradiation and represent a significant portion of clones detected with the use of mwh genetic marker. Our experiments shown that gamma-irradiation occur to be more efficient inductor of such small clones. Earlier small clones were considered as a result of the induced chromosomal aneuploidy of those low proliferating cells. Our data suggest that the small clones descend from the low proliferative cells of non-imaginal disc origin that migrate to the wing imaginal disc at some developmental point.
