The examination of beta-galactosidase (beta-gal) expression in the third segment of the antenna of the 2216 enhancer trap line in Drosophila melanogaster reveals two distinct spatial and temporal regulatory patterns of expression during adult life. Type 1 expression is characterized by a decline in the level of beta-gal expression with increasing age. Starting from a maximal level of expression at the time of adult emergence, there is a decrease in the number of cells that express beta-gal so… CONTINUE READING
