Biogenic amine receptor gene expression in the ovarian tissue of the honey bee Apis mellifera

Dopamine receptors are expressed in ovaries of workers. Their expression is strongly correlated with the reproductive
status of workers. It is possible that dopamine is involved in regulation of worker sterility Biogenic amine receptor gene expression in the ovarian tissue of the honey bee Apis mellifera,
