The dosage compensation system of Drosophila is co-opted by newly evolved X chromosomes
Article Abstract:
The binding of male-specific lethal (MSL) proteins, which mediate dosage compensation in Drosophila melanogaster, correlates with the evolution of the X chromosome. In species that have acquired a second X chromosome arm, due to an X-autosome translocation, MSL binding to the new arm occurs only when its homologue has degenerated. In Drosophila miranda, the pattern of MSL binding to the new X chromosome correlates with the known ways of dosage compensation.

Male-specific fruitless specifies the neural substrates of Drosophila courtship behavior
Article Abstract:
Genetic, developmental, and behavioral studies suggest that the fruitless (fru) gene encodes a set of male-specific transcription factors [Fru(super M)] that act to establish the potential for courtship in Drosophila. The yeast GAL4 gene is inserted into the fru locus by homologous recombination to demonstrate that Fru(super M)] proteins specify the neural substrates of male courtship.

Median bundle neurons coordinate behaviors during Drosophila male courtship
Article Abstract:
Attempts made to eliminate male-specific isoforms [Fru(M)] expression in one group of about 60 neurons in the Drosophila central nervous system is presented and the severely contracted courtship behavior, including rapid courtship initiation, absence of orienting and tapping, and the simultaneous occurrence of wing vibration, licking and attempted copulation is observed.
