Good reception in fruitfly antennae
Article Abstract:
Some insects can sense pheromones from several miles away. The genes for olfactory receptors in vertebrates and Caernorhabditis elegans, the nematode worm, are well known, but they are elusive for their insect counterparts. New reports have identified genes for olfactory receptors in Drosophila melanogaster, the fruitfly, using genomic DNA sequences. Clyne and colleagues used a pure in silico approach to identify two candidate genes . Vosshall and colleagues identified an olfactory-specific rare messenger RNA, and both groups discovered further transmembrane homologues.

Splits in fruitfly Hox gene complexes
Article Abstract:
The homeotic genes in Drosophila virilis are into two separate clusters, like the homeotic genes in Drosophila malenogaster, a closely related genes. However, while the split in the D. melanogaster is into the two separate clusters Antennapedia complex and the Bithorax complex (BX-C), that in the D. virilis occurs within the Bithorax ccomplex alone. These two independent splits in two Drosophila speciesindicates that the fruitflies do not have the molecular constraint which is responsible for ordered clusters in other animals.

Memories of a fruitfly
Article Abstract:
The learning in fruitfly depends on the Rutabaga enzyme and show that to learn visual patterns, the fly must have a Rutabaga in a brain region known as the central complex. Rutabaga enzyme is a calcium-calmodulin-dependent adenylyl cyclase that could be a molecular site for the convergence of signals from the cued stimulus and the reinforcement.
