Sampling plants
Plants (stem segments, leaf and root materials) were collected
from different sites of the tropical rainforests in
Xishuangbanna, Yunnan province, during the period
November 2004–April 2005. Each plant selected for endophytic
actinobacteria isolation was based on its properties
used by Dai people. Plant samples were tagged, stored in
a clean plastic bag and taken to the laboratory.
