摘要/Abstract

摘要： 造礁石珊瑚白化死亡现象日益频繁, 严重时会造成珊瑚礁退化。温度、光和环境化学毒物胁迫是导致造礁石珊瑚大量白化的重要原因, 而造礁石珊瑚白化机制假想模型认为造礁石珊瑚的关键功能基因参与并影响珊瑚白化过程。利用基因芯片等分子生物学技术研究表明关键功能基因的表达和调控状况与珊瑚白化死亡或恢复有密切关系。本文概括了该领域的重要研究进展, 并重点介绍了造礁石珊瑚的几个白化相关功能基因家族的研究状况, 包括温度相关基因家族、光辐射相关基因家族、细胞防御相关基因家族、Ca²⁺平衡相关基因家族和其他重要基因家族。目前, 我国珊瑚功能基因的研究仍处于探索阶段, 因此, 应该加强该领域的研究, 为造礁石珊瑚白化机制研究提供基础理论。

Abstract: Coral reef bleaching appears frequently nowadays, and even leads to degradation of coral reefs. Thermal, light and environmental toxicant stress are the main causes of coral bleaching. A proposed model of coral bleaching suggests that some functional genes are involved in bleaching process. Micro-array analysis can detect functional genes that are crucial in bleaching. This article summarized the progress in the related area, and focused on introducing important function genes that are related to bleaching. These genes include temperature-related gene family, light radiation-related gene family, cellular defense gene family, Ca²⁺ regulated gene family, and other important genes. The research on coral bleaching in China is behindhand the world, and research using gene expression markers will help to expand basic theory of coral bleaching.

Key words: coral reefs, bleaching, stress response, gene expression, micro-array
