title: [Effect of plasmid R6K on the radiation resistance of Escherichia coli K-12 cells].
abstract: In y; Dp(1;3)scJ4, y+M(3)i55Pc2 ssak/mwh ssak stock, somatic y; mwh M+ clones were induced at different developmental stages by 60Co gamma-irradiation (1000 rad; 12,2 rad/sec). Expression of Pc2 (the development of sex-combs on the 2nd and the third leg-pairs) in the non-M clones was similar to that in y; Dp(1;3)scJ4, y+M(3)i55 Pc2ssak/mwh ssak flies, but significantly lower than in Pc2 ssak/+ssak flies. Such non-autonomous Minute effect may be due to the early repression of the Pc prior to the period of clone induction.
