They were alexandrtum tamarense . gymnodinium sp . and niuschia pungens 由此可见， ? ?湖初级生产力极其异常，有爆发赤潮的高度危险。

2 . the primary classification of a gymnodinium sp . ( gyn - 15 ) , whose species name was undetermined 2 .对裸甲藻属未鉴定种( gyn一15 )进行了初步鉴定。

The blastn results show that gyn - 15 is closely related to a symbiont of anemones , s . californium , and the free - living strain , gymnodinium varians . sequence comparison show that the similarities among each part of the sequences from these three strains are all above 99 % . phylogenetic reconstruction with neighbor - joining ( nj ) method using sequences of variable regions ( v1 + v2 + v3 ) of ssu rdna indicated that gyn - 15 , s . californium and g . varians form a new clade with 100 % bootstrap support 以ssurdna序列中的三个可变区( vz + vz + v3 )和邻接法困eighbor一joiningmethod ， nj法)构建共生甲藻属的系统进化树表明， gyn一巧与5 . cal扣rnium和g . varian :在共生甲藻属内构成一个独立的、自检支持百分率为100 %的子类群( clade ) ，根据这些结果可将gyn一巧初步鉴定为属于共生甲藻属。

In contrast , sequences from two strains gymnodinium are divergent ( the sequence similarities of the small subunit ( ssu ) rdna , the its1 , the 5 . 8s rdna , the its2 and the large subunit ( lsu ) rdna are 76 . 5 % , 25 . 4 % , 54 . 2 % , 23 . 2 % , 56 . 5 % , respectively ) , though their phylogenetic positions are relatively close ，编号为gyn - 15 ) 、一株米氏裸甲藻( gymnodiniummikimotoi ) )虽然进化距离接近，但它们的rdna序列相似性却很低，全长序列的相似性仅为54 . 1 。
