Expression data from adult male and female Drosophila melanogaster antenna, proboscis, and front leg

Sex-specific gene expression in sensory organs may play an important role in mating and foraging behavior. We used long-oligonucleotide microarrays to compare gene expression profiles of males and females in three adult appendages that carry large numbers of chemosensory organs – antenna, proboscis, and front leg. Keywords: tissue-specific expression profiles Drosophila isogenic line WI89 was used. Adult male and female antennae (a3+arista), front legs (from distal tibia down), and proboscises were dissected at 1-2 hours after eclosion. Total RNA was extracted and the mRNA fraction was amplified by reverse transcription followed by in vitro transcription with T7 RNA polymerase.
