Description	Journal: Insect Molecular Biology Serotonin (5-HT) modulates various aspects of behaviours such as aggressive behaviour and circadian behaviour in the cricket. To elucidate the molecular basis of the cricket 5-HT system, we identified 5-HT-related genes in the field cricket Gryllus bimaculatus DeGeer. Complementary DNA of tryptophan hydroxylase (TRH) and phenylalanine-tryptophan hydroxylase (TPH) which convert tryptophan into 5-hydroxy-L-tryptophan (5-HTP), and that of aromatic L-amino acid decarboxylase (AADC) which converts 5-HTP into 5-HT were isolated from a cricket brain cDNA library. In addition, four 5-HT receptor genes (5-HT_[1A], 5-HT_[1B], 5-HT_[2α], and 5-HT7) were identified. Expression analysis of TRH and TPH, which are selectively involved in neuronal and peripheral 5-HT synthesis in Drosophila, suggested that two 5-HT synthesis pathways co-exist in the cricket neuronal tissues. The four of 5-HT receptor genes were expressed in various tissues at differential expression levels, suggesting that the 5-HT system is widely distributed in the cricket
