RT Journal Article SR Electronic T1 Molecular transfer of a species-specific behavior from Drosophila simulans to Drosophila melanogaster JF Science JO Science FD American Association for the Advancement of Science SP 1082 OP 1085 DO 10.1126/science.1900131 VO 251 IS 4997 A1 Wheeler, DA A1 Kyriacou, CP A1 Greenacre, ML A1 Yu, Q A1 Rutila, JE A1 Rosbash, M A1 Hall, JC YR 1991 UL http://science.sciencemag.org/content/251/4997/1082.abstract AB Drosophila males modulate the interpulse intervals produced during their courtship songs. These song cycles, which are altered by mutations in the clock gene period, exhibit a species-specific variation that facilitates mating. We have used chimeric period gene constructs from Drosophila melanogaster and Drosophila simulans in germline transformation experiments to map the genetic control of their song rhythm difference to a small segment of the amino acid encoding information within this gene.
