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.

Porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) are very two important pathogens that have coursed huge economic losses in swine production in worldwide. In this study,a vector pCMV-TJM containing the full-length cDNA clone of PRRSV attenuated strain TJM-F92 was firstly constructed by PCR method. Then a gene sequence containing Afl II/Mlu I e restriction enzyme sites and a transcription regulatory sequence for ORF6 (TRS6) was inserted be- tween ORF7 and 3'UTR, yielding a expression vector pCMV-TJM-TRS. Subsequently, a plasmid pCMV-TJM-Cap was constructed by cloning of PCV2 ORF2 gene into the unique sites Afl II /Mlu I of pCMV- TJM-TRS plasmid DNA. Then three recombinant PRRSV, rTJM, rTJM/TRS and rTJM/Cap, were rescued by transfection of pCMV-TJM, pCMV-TJM-TRS and pCMV-TJM-Cap into Marc-145 cells, respectively,and confirmed by the genome sequence, restriction enzyme digestion, Western Blot and IFA. They all had the molecular markers which was different from the parent virus. The growth characteristics of the rescued viruses were similar to that of parent virus. rTJM/Cap could also express efficiently PCV2 Cap protein in Marc-145 cells. At passage 8, it still had PCV2 ORF2 gene which examined by RT-PCR. It indicated that the full-length cDNA clone of PRRSV attenuated strain TJM-F92 and recombinant PRRSV rTJM/Cap expressing PCV2 Cap protein were successfully constructed. It made an important foundation for studying on the pathogenic mechanisms of PRRSV and PRRSV-PCV2 vaccine in the future.
