Keyword:  黄藻多甲藻素系统演化;
Abstract: 采用聚酰胺薄层层析分离、分光光度法,对一种海生超微型黄藻品系PP983的色素组成进行了研究测定.结果表明,该黄藻中只含有叶绿素a而不含叶绿素c,检出8种类胡萝卜素,除作为黄藻特征色素的Heteroxanthin和Vaucheriaxanthin两种外,还发现该藻含有一个吸收峰在471nm,呈现多甲藻素(peridinin)特征的色素.用高效液相色谱(HPLC),并以微小多甲藻(Peridinium pusillum)作对照,对其光合色素作进一步的分析,确证该黄藻中不含有叶绿素c而含多甲藻素.结果显示此种黄藻与甲藻有更近的亲缘关系.初步讨论了黄藻中多甲藻素的存在及其在藻类系统演化中的意义.
