Abstract

|
As a first step for developing universal genetic transformation vector of dilkmoths., we identified the presence of mariner-like element(MLE) which is one of transposable element discovered from many insects to human species, from Bombyx mori, Bombyx mandarina, Antherae yammamai and Antherae pernyi. We used a degenerative primer pair designed from a transposase gene of Drosophila mauritiana and Hyalophora ceropia MLE. As results, major PCR product of 500bp expected as a part of transposase of MLE was detected from all the slkmoths used of this study using these primer. And hybridization assay using pBmoMAR as a probe DNA that was previously cloned from Bombyx mori by the same primer pair, confirmed the presence of MLE from all the silkmoths. This assay showed also that the endogenous MLE in genome of the silkworm is present as high copy number unlikely Drosophila mauritiana which has 10-20 copy number. This data will be a fundamental genetic information for developing mariner-derived vector to transform the silkmoths and other useful insects.
