摘　　要：本文对分离于我国海南三亚鹿回头海域的两株虫黄藻SYSC-14-11和SYSC-2-8进行了分类学研究。通过光学显微镜、扫描电子显微镜和分子生物学方法描述了两株藻的形态和系统发育特征,并与世界其他地理区系的Effrenium属虫黄藻进行了差异性比较,发现本研究中的两株虫黄藻的形态和系统发育特征与Effrenium属虫黄藻模式种Effrenium voratum基本一致,推测本文中的两株Effrenium属虫黄藻均为E.voratum。本研究丰富了我国热带海域虫黄藻的物种多样性,为完善我国的虫黄藻种质资源奠定了基础。In this study,we analyzed taxonomy of two strains(SYSC-14-11 and SYSC-2-8)of zooxanthellae isolated from the Luhuitou reef region in Sanya.Morphological characteristics were determined by light microscope and scanning electron microscope,while phylogenetic analyses were constructed based on the sequences of the LSU rDNA and the internal transcribed spacer sequence(ITS2).The results showed that the morphological and phylogenetic characteristics of the two strains in the present study were basically consistent with Effrenium voratum reported in other geographical regions of the world.This study enriches the species diversity of zooxanthellae in the tropical coral reef ecosystems,and provides a solid foundation for further utilizing the resources of zooxanthellae.
