The fruit fly Drosophila is a genetically tractable model system that can be used to understand sex-specific differentiation. Sex-specific somatic tissue differentiation and the potential for male courtship behaviors are specified by a genetic regulatory hierarchy, called the sex determination hierarchy. These sex-specific differences are genetically specified, and so can be examined using the myriad of powerful tools developed to study Drosophila.

520 $a The fruit fly Drosophila is a genetically tractable model system that can be used to understand sex-specific differentiation. Sex-specific somatic tissue differentiation and the potential for male courtship behaviors are specified by a genetic regulatory hierarchy, called the sex determination hierarchy. These sex-specific differences are genetically specified, and so can be examined using the myriad of powerful tools developed to study Drosophila.
520 $a The sex determination hierarchy consists of an alternative pre-mRNA splicing cascade culminating in the production of sex-specific transcription factors encoded by fruitless (fru) and doublesex (dsx). Male-specific splicing of on transcript class, fru P1 (producing FRUM), is necessary for all aspects of male courtship behavior. dsx is required for sex-specific development of nearly all somatic tissues outside of the central nervous system and aspects of nervous system development. Despite our detailed knowledge of the hierarchy, little is known regarding the targets of these transcription factors which ultimately specify sex-specific somatic tissue development and pattern the neural circuitry underlying sex-specific behavior.
520 $a Identifying genes regulated downstream of FRUM and DSX in the adult head and nervous system tissues is important for the understanding of how the potential for behaviors are established and maintained. Using a microarray-based approach, we have identified many genes regulated downstream of DSX and FRUM activity in these tissues. Functional analyses and understanding how these genes are deployed by the sex determination hierarchy provides insight into how a regulatory network functions on a genome-wide scale.
520 $a We characterized several genes, including a DSX-regulated gene known to play a role in visual transduction, and a FRUM-regulated gene which functions in the timing of male courtship behavior. We present extensive analyses of neurons which express a gene regulated downstream of FRUM. These neurons appear to function in both the FRU M and the circadian pacemaker circuits. We show that ablating, or electrically silencing these neurons results in defects in male courtship behavior and circadian periodicity.
520 $a We developed a web-based transcription factor binding site search program which predicts regulatory regions known as cis-regulatory modules based on significance of transcription factor binding site clustering. We used this in silico method in conjunction with expression data to identify potential DSX and FRUM direct targets.
