Abstract:
To study the ecological distribution and diversity of endophytic fungi associated with Ferula of medicinal plants in Xinjiang. The endophytic fungi were isolated from roots, stems and leaves of Ferula by microbiology research methods and technology. The endophytic fungi were identified using ITS rDNA sequence analysis and morphology analysis. The composition, diversity and preference of endophytic fungal community were analyzed with Shannon-Wiener biodiversity index (H') and Sorensen coefficient (Cs). A total of 337 strains endophytic fungi were isolated and classified into 38 genera, Alternaria, Aureobasidium and Fusarium were the dominant genera. Among the 337 isolates, the endophytic fungi of F. sinkiangensis were the most, The Shannon-Wiener biodiversity index (H') associated with roots of F. fukanensis was the highest, reached 1.85. The highest Sorensen coefficient ( Cs) was between leaf of F. sinkiangensis and leaf of F. ovina, reached 0.75. From the result, endophytic fungi were widely distributed in six Ferula, there are some notable differences between distribution and composition of the endophytic fungi isolated from different issues and different species of Ferula, show a certain degree of species and tissue preference. The results obtained in this study will provide realistic basis and theoretical basis for further study the secondary metabolites of endophytic fungi associated with Ferula, and the relationship between endophytic fungi and their host plants.
