图5 基于ITS序列以Maximum Likehood法构建的Phytophthora nicotianae系统发育树编号PYA1和PYA2分别为实验菌株ITS1/ITS4和特异引物Pn1/Pn2扩增出来的2个序列,其他为NCBI上下载的可信度高的菌株序列。 Fig. 5 Maximum Likehood phylogenetic tree based on rDNA-ITS sequences of Phytophthora nicotianae PYA1 and PYA2 were two sequences of isolate from Phytophthora blight of Spathiphyllum sp. which were amplified by primers ITS1/ITS4 and Pn1/Pn2 , other sequences were from NCBI with high credibility. |
