Abstract
The Bradysia hygida (Diptera, Sciaridae) DNA puff C4 BhC4-1 gene is amplified and expressed in a developmentally regulated manner in the salivary gland at the time DNA puff C4 is formed. Since it is not possible to perform functional assays in Sciaridae, the BhC4-1 regulation is studied in Drosophila, a system in which the pattern of BhC4-1 expression is largely conserved. In transgenesis…
