Drosophila development is marked by two major morphogenetic processes: embryogenesis and metamorphosis. While insect metamorphosis is known to be controlled by the steroid hormone ecdysone, relatively little is known concerning the hormonal control of embryogenesis. Here we show that many ecdysone-regulated transcripts of metamorphosis are also expressed in a wavelike manner during embryogenesis, suggesting that these genes also participate in an embryonic ecdysone response. At metamorphosis… CONTINUE READING
