预测珊瑚礁的命运的关键是造礁珊瑚适应和适应气候变化的能力。跨代可塑性可能使一些海洋生物能够适应几代人的环境，有人假设，表观遗传过程和微生物协会可能有助于适应性反应。然而，目前的证据是模棱两可的，对基本过程的理解是有限的。在这里，我们讨论了观察珊瑚的跨代可塑性的前景和机制，可以使适应性可塑性的珊瑚holobiont，包括表观遗传学和珊瑚相关的微生物的潜在作用。需要精心设计和严格控制的实验来区分跨代可塑性和其他形式的可塑性，并阐明潜在的机制及其相对于遗传适应的重要性。
Pivotal to projecting the fate of coral reefs is the capacity of reef-building corals to acclimatize and adapt to climate change. Transgenerational plasticity may enable some marine organisms to acclimatize over several generations and it has been hypothesized that epigenetic processes and microbial associations might facilitate adaptive responses. However, current evidence is equivocal and understanding of the underlying processes is limited. Here, we discuss prospects for observing transgenerational plasticity in corals and the mechanisms that could enable adaptive plasticity in the coral holobiont, including the potential role of epigenetics and coral-associated microbes. Well-designed and strictly controlled experiments are needed to distinguish transgenerational plasticity from other forms of plasticity, and to elucidate the underlying mechanisms and their relative importance compared with genetic adaptation.
