Evolutionarily, serotonin existed in plants even before the appearance of animals. Indeed, serotonin may be tied to the evolution of life itself *1
In plants, serotonin has been suggested to be involved in several physiological roles, including flowering, morphogenesis, and adaptation to environmental changes *2
It has been found that Serotonin-like molecules direct the growth of light-capturing structures (in plants) towards the source of light. *1
Research by Susan J. Murch et al. provides evidence that a balance of the endogenous concentration of serotonin and melatonin may modulate plant morphogenesis in vitro. *3
Serotonins regulation and functional roles are however unfortunately as yet not characterized at the molecular level. *2
We believe that there are many secrets to be unlocked through understanding the relationships between research chemicals, serotonin and plants.
We encourage plant scientists to investigate this novel research topic and have dedicated this website to providing an easy place to purchase the often hard to source research chemicals needed to conduct such research.
