摘　　要：报道了一种快速制备PCR扩增甲藻细胞模板DNA的方法。以赤潮甲藻塔玛亚历山大藻(Alexandriumtamarense)和链状亚历山大藻(A.catenella)为目标藻,对藻液预处理后直接用于PCR扩增,获得5.8S核糖体RNA基因及其两侧的核糖体RNA基因转录单元内基因间隔区(internaltranscribedspacer,ITS)序列片段,成功测序。此方法避免了复杂的DNA提取过程。A method for quickly preparing PCR amplification of dinoflagellate total DNA template was reported. Alexandrium tamarense and A. catenella were solved in advance and used as template of PCR amplification. The production of internal transcribed spacer including 5.8s RNA gene was sequenced. It was demonstrated that the method was simple and useful to molecular analysis of dinoflagellate.
