Abstract
Phylogenic relationships of Rhizoctonia isolates of wormwood root between wormwood root endophytes and root soils fungi were investigated using fatty acid analysis and compared with their fatty acid methyl ester (FAME) profiles. The modified MIDI method was used and allowed a clear differentiation between the two Rhizoctonia and Rhizoctonia-like fungi, and fatty acid analysis was identified and classified these isolates as the Rhizoctonia serialis (AG-D). However, isolates of wormwood root endophyte was identified as AG-D (I), and isolates of Rhizoctonia-like fungi from wormwood root grown soils was identified as AG-D(II), respectively. In this experiment, we discovered the subgroup within same AG-D isolates and characterized the endophytic and endophytic related criteria within the same anastomosis groups and homologous to the subgroups levels.
