[Analysis of endophytic fungi community of Ligusticum chuanxiong using PCR-DGGE].

Objective: To research the diversity of endophytic fungal communities among Ligusticum chuanxiong growing at 5 areas in Sichuan province, and illuminate the developing mechanism of geoherbs from the microecological perspective.
Method: The PCR-DGGE and DNA sequencing techniques were used to analyze the endophytic fungi community of L. chuanxiong.
Result: The community of endophytic fungi present difference among different growing areas. Though minor difference were found among individuals at the same area, similarity among individuals from the same growing areas were higher significantly than those from different growing areas. Compared with the other 4 growing areas, L. chuanxiong from Shiyang town, Dujiangyan city had more abundant endophytic fungi and low similarity to others, and which probably had special types of fungi.
Conclusion: The abundant and stable endophytic fungal community is an important factor for the development of geoherb L. chuanxiong at Shiyang town, Dujiangyan city.
