Research Abstract

We aimed to clone and characterize the Voltinism gene that isconceived to control the biosynthesis and release of diapause hormone, an inducer ofBombyx mori embryonic diapause. By positional cloning and analyses of the geneexpressions and the deduced amino-acid sequences, we had five candidate genes. Now, weare analyzing such gene structures.
