摘要:
造礁石珊瑚共生藻的系统分类研究对于理解珊瑚礁生态系统对全球变化的响应具有十分重要的意义。本研究利用PCR技术扩增核糖体基因大亚基片段以及限制性片段长度多态性(RFLP)的方法, 对海南三亚鹿回头岸礁的8科14属22种造礁石珊瑚的共生藻组成进行了研究。结果表明鹿回头岸礁造礁石珊瑚共生藻以C系群为优势系群, 偶尔发现D系群与鹿角杯形珊瑚(Pocilolpora damicornis)和黄癣蜂巢珊瑚(Favia favus)共生; 另外丑鹿角珊瑚(Acropora horrida)和丛生盔形珊瑚(Galaxea fascicularis)可以同时与C系群和D系群共生。共生多型性的发现暗示珊瑚与共生藻的共生关系具有灵活性。研究结果同样显示共生藻的核糖体基因大片段的DNA多态性偏低。未来应该结合其他的分子标记对鹿回头岸礁造礁石珊瑚共生藻的DNA多态性进行更深入的研究。
