 .A mutant M47286 with a stunted growth, low fertility and dark-brown phenotype was identified from a T-DNA-tagged rice mutant library. This mutant contained a copy of the T-DNA tag inserted at the location where the expression of two putative tryptophan decarboxlyase genes, TDC -1 and TDC - 3 , were activated.

 tryptophan decarboxlyase activities that converted tryptophan to tryptamine, which could be converted to serotonin by a constitutively expressed tryptamine 5'hydroxylase (T5H) in rice plants.transgenic plants that produced TDC showed a normal phenotype and contained 25-fold and 11-fold higher serotonin in the leaves and seeds, respectively, than the wild-type plants.
 .over-expression of TDC results in stunted growth, low fertility and the accumulation of serotonin, which when converted to serotonin dimer, leads to a dark brown plant color.The degree of stunted growth and dark-brown color was proportional to the expression levels of TDC-1. The levels of tryptamine and serotonin accu-mulation in these transgenic rice lines were also directly

 ===Evolution===
+Serotonin (5-hydroxytryptamine) is a well-known aromatic amine neurotransmitter that controls several important physiological functions such as mood, sleep and anxiety in animals and humans.
+Evolutionarily, serotonin existed in plants even before the appearance of animals, with the first report coming in the fruit of the cowhage (Mucuna pruriens ) plant.Similar to the multiple roles played by serotonin in animal cells, serotonin has also been sug-gested to be involved in several physiological functions in plants, such as growth regulation , seed germination, flowering, ion per-meability, adaptation to environmental changes and morphogenesis. Recently, serotonin has been reported to accumulate in rice leaves to delay senescence and at
