Endophytic fungi are common in living tissues of
plants and have an abundant species diversity [5]. They can generally
improve their host’s resistance to severe environment and thus
enhance the abilities of ecological competition [6]. On the other
hand, endophytic fungi can produce the same or similar active natural
products as the host plants. They are important resources from
which natural products with the new structure or new activities
can be obtained [7]. It is an important foundation to understand
the community composition for the studies of ecological value,
plant adverse resistance, natural active ingredients and so on.
