Based on 16S rDNA sequences, phylogenetic trees of the
35 strains from Dioscorea bulbifera, Chenopodium album,
and Populus adenopoda were separately constructed and
analyzed in the present study. Other isolates from Podocarpusmacrophyllus, Forsythia suspensa, and Solanum torvum have
been published in previous reports [34-35]. 16 strains isolated
from D. bulbifera were sorted to seven different clades (Fig.
2). 11 strains isolated from C. album and eight strains from P.
adenopoda were both sorted to six different clades (Figs. 3
and 4), with 8 isolates from P. adenopoda being affiliated to 4
genera. All the three groups showed considerable high
diversity among the medicinal plants. These results suggested
that actinomycetes inhabited in the unique niches inside
medicinal plant tissues with abundant diversity of genotypes.
Streptomyces was the most frequently isolated genus from
these plants, and rare actinomycetes were demonstrated to be
able to dwell interiorly too.
