Multiplicity of signals and diversity of signaling pathways exist during the establishment of mycorrhizal associations together with the regulation of symbiosis - specific genes expression . this mechanism of signal recognition and transduction related with development process of the symbiont was reviewed at the molecular level 在菌根共生体建立过程中存在信号分子的多重性和信号通路的多样性以及共牛体特异基因的表达调控,从分子水平上揭示了菌根整个发育过程。

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。
