Control of antennal versus leg development in Drosophila

Article Abstract:

It has been possible to identify four lines of evidence that show extradenticle (exd) and homothorax (hth) to be antennal-determining genes in Drosophila melanogaster. It seems that exd and hth generate antennal identities, with hth contributing to antennal development in more ways than by localizing Exd to the nucleus. It is likely that Hth, like Exd, is a DNA-binding transcription factor. This research supports the view that the ancestral insect possessed leg-like appendages in head and thoracic segments.
