Involvement of GLWamide neuropeptides in polyp contraction of the adult stony coral Euphyllia ancora.

ABSTRACT: The existence and function of neurons remain largely unexplored in scleractinian corals. To gain a better understanding of neuronal functions in coral physiology, this study focused on Glycine-Leucine-Tryptophan-amide family neuropeptides (GLWamides), which have been shown to induce muscle contraction and larval metamorphosis in other cnidarians. Molecular identification and functional characterization of GLWamides in the adult stony coral Euphyllia ancora were performed. We successfully elucidated the full-length cDNA of GLWamide preprohormone in E. ancora (named EaGLW preprohormone). The deduced amino acid sequence was predicted to contain six potential GLWamide peptides. Tissue distribution analysis demonstrated that transcripts of EaGLW preprohormone were mainly expressed in the mouth
