In this study, we cloned and analyzed the multifunctional <i>Ostrinia furnacalis</i> AKHR (OfAKHR) cDNA (GenBank accession number MF797868). <i>OfAKHR</i> has a 2206 bp full-length cDNA, which includes an open reading frame containing 1194 bp.

These CP genes responded to ecdysone and ecdysone pulse; therefore, CP genes were applied for the analysis of transcriptional regulation by ERTF. The binding sites of ERTF have been reported to exist upstream of CP genes in several insects, and the activation of CP genes occurred by the binding of ERTFs.
