| Abstract: | Male courtship ritual is among the main behavioral characteristics of Drosophila. This is a complex, genetically determined process consisting of four general stages: orientation, vibration, licking, and attempts at copulation (or successful copulation). Several genes are known that control some stages of this behavior. Most of them have pleiotropic effects and are involved in other biological processes. Earlier, we have shown that a mutation in locus flamenco (20A1-3), which controls transposition and infectivity of retrotransposon gypsy (MDG4), is involved in the genetic control of behavior. In strains mutant for this locus, the male mating activity is decreased and the structure of courtship ritual is changed. To understand the mechanisms of these changes, it is important to study all behavioral stages in genetically identical strains. For this purpose, the normal allele of gene flamenco from the X chromosome of the wild-type strain (stock) Canton S was introduced into strain SS carrying flamMS. This offers new opportunities in studying the role of gene flamenco in the control of mating behavior in Drosophila. |
