A Single MicroRNA-Hox Gene Module Controls Equivalent Movements in Biomechanically Distinct Forms of Drosophila (Current Biology)

Issa, Picao-Osorio et al. explore the molecular cellular basis of behavior. Through the combination of gene expression, optical imaging, and quantitative behavioral analyses in Drosophila, they show that a single genetic module--including a microRNA and a Hox gene--controls functionally equivalent movements in biomechanically distinct organisms.
