Activity analysis of ASH2P promoter by co-transfected with Bm-ASH genes. In the figure, ASH2P stands for the recombinanted plasmid pGL3-Basic-ASH2P; ASH1, ASH2, ASH3, ase and da respectively stands for the modified transient expression vector pBacPAK8-ie1-hr3 containing Bm-ASH1, Bm-ASH2, Bm-ASH3, Bm-ase and Dm-da (daughterless) ORFs as transcriptional factor genes. At least three independent repeats were carried out for each treatment.
