A factor that affects synthesis of sericin mRNAs of Bombyx mori was analyzed by organ transplantation and allatectomy. When silk glands of the third instar larvae were transplanted into the abdomen of fifth instar larvae, substantial amounts of sericin mRNAs were induced in the transplant. The induced sericin gene activity was suppressed upon re-transplantation into the abdomen of fourth instar larvae and induced again when the second hosts grew up to fifth instar larvae. An allatectomy performed on fourth instar larvae promoted production of these mRNAs, suggesting that the synthesis of sericin mRNA is regulated by the titer of juvenile hormone.
通过器官移植和去咽侧体手术分析了影响家蚕丝胶蛋白mRNA合成的一个因素。将三龄幼虫的丝腺移植到五龄幼虫腹部时，移植体中会诱导产生大量丝胶蛋白mRNA。当再次移植到四龄幼虫腹部时，诱导的丝胶基因活性受到抑制，而当第二宿主成长到五龄幼虫时又会再次诱导产生。对四龄幼虫进行去咽侧体手术会促进这些mRNA的产生，这表明丝胶蛋白mRNA的合成受保幼激素滴度的调节。
