结果表明，同属三种植物的形态特征相似，可通过叶形及花期是否具基生叶，花萼的形态，花冠颜色以及茎的生长方式和植株被毛情况等予以鉴别；通过对三种植物的花、根、茎、叶及全草粉末的组织构造观察，认为种间差异较小，可依据毛茸的分布及形态特征和茎的木化程度不同加以鉴别；对三者花粉粒进行了扫描电镜观察，发现其大小和外壁纹饰具有明显差异，为三者的鉴别提供了有力的依据，也为该属的分类及植物花粉形态研究提供了花粉形态学方面的资料。

PmMYB is a typical R2, R3-MYB transcription factor with its 2 typical DNA-binding domains (amino acid sites of 13-63 and 66-114).The multiple alignment of R2, R3 amino acid repeat regions of MYB genes among broomcorn millet, rice, corn, loblolly pine, Arabidopsis, capsicum, upland cotton, barley and aubergine indicates that R2, R3 repeat regions are very conserved. The phylogenetic analysis based on amino acid sequence shows that MYB genes are highly divergent with similarity ranging from 32% to 84%.

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.

The cDNA document of ACC oxidase gene of Citrus aurantium L. was cloned. By using the program of BLAST on NCBI GenBank database, the sequence presented a very high match with the ACC oxidase genes from other plants. The base sequence was analysed by using biology programe of DNAStar 5.0. 278 amino acids were coded by the base sequence and the base sequence had the same conserve region of ACC oxidase gene of many kinds of other plants. The base sequences comparability was more than 72% compared with those of many kinds of other plants. The amino acid sequences comparability was more than 70% compared with those of a lot of other plants.

When the frequency of codon usage of citrus was compared to Homo sapiens, Drosophila melanogaster, Saccharomyces cerevisiac and Escherichia coli, we found that the codon preference is considerably different between citrus and non-plant species. While compared to Arabidopsis thaliana, Lycopersicon esculentum, Oryza sativa and Musa acuminata, we found that the codon preference was identical in dicotyledons, but was different between citrus and monocotyledon, Oryza sativa and Musa acuminate.
