In this research, swainsonine contents of three Oxytropis species were determined by the high performance liquid chromatography coupled to mass spectrometry. The population genetic diversity was also studied and the swainsonine related molecular markers were screened by ISSR. In vitro fungi cultures from the individual plant of O. glabra were performed and microbiological morphology of the colony and the conidiophore were investigated. The 5.8S rDNA/ITS sequences of fungi amplified from total DNA in both plants and fungal endophytes were studied. These sequences were analysed and compared, and they were also compared to the 5.8S rDNA/ITS sequence of fungal enduphyte Embellisia sp. L12 from the O.lambertii, O.sericea and A.mollisimus distributed in USA.

However, the area is less studied than other areas of endophyteresearch world wide. Therefore, a series of experiments were carried out in laboratory,glasshouse and field to compare the responses of endophyte infected plants andendophyte free plants of perennial ryegrass varieties to 10 fungal pathogensisolated from turf type ryegrass in Lanzhou. The pathogens used in the experimentswere Alternaria alternata、Bipolaris sorokiniana、Fusarium avenaceum、Curvularialunata、Ascochyta leptospora、Fusarium acuminatum、Fusarium chlamydosporum、Fusarium oxysporum、Fusarium solani and Gliocladium roseum. In addition, someprotective enzymes activity and alkaloids contents of E+ and E- plants were measuredand LpsA gene of the common strain - Lp19 and mutant strain -AR1 of Neotyphodiumlolii were sequenced to identify their ...

A relationship between the frequency of occurrence and diversity of AM fungi and the elevation of the sampling sites for Swietenia macrophylla was observed. The elevation significantly affected the frequency of occurrence and diversity of Gigaspora and Scutellospora, but showed no significant influence to Glomus and Acaulospora.

The universal primers of ITS1 and ITS4 for fungi were used in amplification of genomic rDNA sequences. A target fragment was obtained by ITS-PCR. Then, the fragment is cloned into the vector of pMD18-T before sequencing. The result of sequencing showed that the fragment is 692 bp in length. The results of Blast in Genbank and the analysis of fungal rDNA systemic development show that the relation between this fragment to the fungi of Sporisorium is closest, while the relation between it to the fungi of Ustilago is much far. It suggests that the name of Ustilago scitaminea for sugarcane smut isn't consistent to the result of rDNA systemic development analysis. It still needs more experiments to support this hypothesis.

用真菌rDNA序列分析的通用引物ITS1和ITS4，通过ITS-PCR得到目的片段，克隆在pMD18-T载体上后进行测序，结果显示该片段的长度为692 bp，与Genebank中已报道的真菌序列进行Blast和系统发育树分析，表明所获得的序列与Sporisorium属真菌具有更高的亲缘关系，而与Ustilago属真菌的亲缘关系较远，这与一直沿用的甘蔗黑穗病菌的命名似乎并不吻合，有待进行更多的研究以证实。

Ninety seven spores or sporocarps of VAMF were wet sieved from the rhizosphere soil of mycorrhized pteridophytes, from which 25 VAMF species which belonged to the genera of Acaulospora, Gigaspora, Glomus, Sclerocystis and Scutellospora respectively were identified, and the taxonomic characters of the 25 species were described. The Glomus fungi were the dominant VAMF in the rhizosphere soil of pteridophytes, they took up 44% in the identified 25 VAMF (11 species belong to Glomus); the fungi in Acaulospora and Sclerocystis in the next place, they took up 24% and 16% respectively in the identified VAMF; the fungi in the other genera took up 16%. In terms of the relationships of pteridophytes and the VAMF isolated from their rhizosphere soil, there was no specifity between the VAMF and their host.

从具有VA菌根的蕨类植物对应的根际土壤中用湿筛法筛取了97份VA菌根真菌的孢子或孢子果，从中鉴定出了分属于无醒囊霉属、巨孢囊霉属、球囊霉属、硬囊霉属和盾孢囊霉属的VA菌根真菌25种，并对这25种真菌的分类学特征进行了描述；球囊霉属真菌是蕨类植物根际土壤中的优势类群，已鉴定的25种真菌中，有11种属球囊霉属真菌，占44%，其次是无梗囊霉属和硬囊霉属真菌，分别占24%和16%，其他属的VA菌根真菌占16%，从分离鉴定的蕨类植物根际土壤中的VA菌根真菌与蕨类植物的关系看，VA菌根真菌与蕨类植物之间无明显的专一性。
