Abstract
Six species of dinoflagellates were investigated for their responsiven ess to the indoleamine melatonin (and its homologue 5-methoxytryptamin e), the vertebrate hormone for circadian rhythm regulation. Five speci es were observed forming pellicle cysts in response to 5-methoxytrypta mine at concentrations around 10(-6) M. Cells of Oxyrrhis marina were observed retracting from the theca, part of the responsive pathway to indoleamine, but the resulting naked cells were unable to form a new c ell wall and lysed.
