The new data suggest that the glutamate receptors and other similar neuro - transmitter receptors may actually evolve from ancestral methods of simple communication , common to plants and animals alike . selective environmental pressure may have led to a higher production of these neurotoxins for defense against predators more recently in evolutionary time . neurotoxins isolated from plants may be originally signalling molecules regulating these plant receptors 林教授指出以往生物學家相信植物制造神經毒素純是為了防御草食類動物的侵襲，但這項植物?氨酸感受器的研究卻指向另一可能性，即神經毒素最初可能是植物用來作訊息傳遞的分子，通過?氨酸感受器和其他類似的感受器來調控植物本身的生命功能。
