刺胞动物和共生甲藻（甲藻）之间的共生关系是形成珊瑚礁这一巨大而重要结构的关键。今天，许多环境和/或人为的威胁损害了这种紧密的关系，并导致更频繁的事件的急剧损失的共生藻色素，并最终藻类本身从刺胞动物，更好地称为刺胞漂白。虽然潜在的机制崩溃的藻类珊瑚共生逐渐得到解开，漂白刺胞动物的共生藻从头感染的机制的理解仍然难以捉摸。在这篇综述中，我们描述了需要建立一个稳定的共生关系共生甲藻和刺胞动物之间的各个步骤。我们回顾了宿主共生体识别和共生体形成和持久性的机制，特别强调凝集素和Rab蛋白所起的作用。更好地了解这些分子机制可能有助于制定战略，以促进珊瑚漂白后的恢复。(C)2012 Elsevier B.

The symbiosis between cnidarians and Symbiodinium algae (dinoflagellates) is the keystone responsible for the formation of the huge and important structures that are coral reefs. Today many environmental and/or anthropogenic threats compromise this tight relationship and lead to more frequent events of drastic loss of Symbiodinium pigments and eventually of algae themselves from cnidarians, better known as cnidarian bleaching. While the mechanisms underlying the collapse of the algae-coral symbiosis are progressively getting unraveled, the understanding of the mechanisms involved in the de novo infection of bleached cnidarians by Symbiodinium remains elusive. In this review, we describe the various steps needed to establish a stable symbiotic relationship between Symbiodinium and cnidarians. We review the mechanisms implicated in host-symbiont recognition and in symbiosome formation and persistence, with a special emphasis on the role played by lectins and Rab proteins. A better understanding of these molecular mechanisms may contribute to the development of strategies to promote post-bleaching recovery of corals. (C) 2012 Elsevier B.V. All rights reserved.
