Abstract
Tyramides are produced in microgram quantities by males of species in the large Myrmicine ant sub-family (> 7000 species). Tyramides are transferred to female sexuals during mating where a specific female sexual evolved enzyme hydrolyzes the tyramides to the biogenic amine, tyramine. Tyramine is a ligand for receptors that rapidly activate reproductive development in the newly mated queen—previously reproductively inhibited by the mother queen. Without this elaborate biogenic amine precursor and co-evolved female sexual derived tyramide hydrolase, the defenseless newly mated queen’s worker production would be delayed by up to 6 days, which could be lethal to the new queen. This is one of possibly several ant species separation mechanisms evolved to maintain species integrity. Here we report two methyl-branched tyramides from harvester ant, Pogonomyrmex badius, males, including one highly branched tyramide not previously reported.
期刊介绍：
The Science of Nature - Naturwissenschaften - is Springer''s flagship multidisciplinary science journal. The journal is dedicated to the fast publication and global dissemination of high-quality research and invites papers, which are of interest to the broader community in the biological sciences. Contributions from the chemical, geological, and physical sciences are welcome if contributing to questions of general biological significance. Particularly welcomed are contributions that bridge between traditionally isolated areas and attempt to increase the conceptual understanding of systems and processes that demand an interdisciplinary approach.
