Both UASt and ms(3)K81 upstream regulatory sequences are fused upstream of a chimeric fusion protein composed of N-terminal two thirds of ms(3)K81 and the C-terminal one third of HipHop. The coding sequence is tagged at the N-terminal end with EGFP.
HipHop::ms(3)K81aKbKcH.UAS.K81.EGFP is a non-suppressor of male sterile phenotype of ms(3)K81unspecified
HipHop::ms(3)K81aKbKcH.ms(3)K81.T:Avic\GFP is unable to suppress the sterility of ms(3)K81unspecified mutants.
