珊瑚幼虫似乎感觉到合适的环境，并通过将外部线索转化为内部信号开始变态，尽管对这些分子机制知之甚少。神经肽家族GLWamides被认为是这种内部信号，在某些水螅动物中起着诱导变态的作用。在这里，我们报告的GLWamide肽家族的成员，Hym-248，可以诱导在鹿角珊瑚属的浮游幼虫变态。扁平鹿角珊瑚对肽的反应呈浓度依赖性。GLWamide肽将模拟内源性分子以在鹿角珊瑚中开始变态，如在水螅虫的情况下。此外，该肽可用于生产“珊瑚苗”，以恢复珊瑚礁。
Coral larvae appear to sense appropriate environments for settlement and start metamorphosis by converting external cues into internal signals, although little is known about these molecular mechanisms. A family of neuropeptides, GLWamides, are thought to be such internal signals, acting hormonally to induce metamorphosis in some hydrozoan species. Here we report that one member of the GLWamide peptide family, Hym-248, can induce metamorphosis of planula larvae in the genus Acropora. The Acropora planulae responded to the peptide in a concentration-dependent manner. The GLWamide peptide would mimic endogenous molecules to start metamorphosis in Acropora as in case of hydrozoans. In addition, the peptide could be applied to produce "coral seedlings" with the aim of reef restoration.
