In order to obtain the fungicides with minimal impact on efficiency of mycorrhizal symbiosis, the effect of five fungicides including polyoxins, jinggangmycins, thiophanate methylate, chlorothalonil and carbendazim on the growth of medicinal plant and efficiency of mycorrhizal symbiosis were studied. Pot cultured Glycyrrhiza uralensis was treated with different fungicides with the concentration that commonly used in the field. 60 d after treated with fungicides, infection rate, infection density, biomass indexes, photosyn- thetic index and the content of active component were measured. Experimental results showed that carbendazim had the strongest inhibition on mycorrhizal symbiosis effect. Carbendazim significantly inhibited the mycorrhizal infection rate, significantly suppressed the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. Polyoxins showed the lowest inhibiting affection. Polyoxins had no significant effect on mycorrhizal infection rate, the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. The other three fungicides also had an inhibitory effect on efficiency of mycorrhizal symbiosis, and the inhibition degrees were all between polyoxins's and carbendazim's. The author considered that fungicide's inhibition degree on mycorrhizal effect might be related with the species of fungicides, so the author suggested that the farmer should try to choose bio-fungicides like polyoxins.

The rhizome of Panax japonicus var. major have been used as the natural medicinal agent by Chinese traditional doctors for more than thousand years. Most of the therapeutic effects of P. japonicus var. major had been reported due to the presence of tetracyclic or pentacyclic triterpene saponins. In this study, Illumina pair-end RNA-sequencing and de novo splicing were done in order to understand the pathway of triterpenoid saponins in this species. The valid reads data of 15. 6 Gb were obtained. The 62 240 unigenes were finally obtained by de novo splicing. After annotation, we discovered 19 unigenes involved in ginsenoside backbone biosynthesis. Additionally, 69 unigenes and 18 unigenes were predicted to have potential function of cytochrome P450 and UDP-glycosyltransferase based on the annotation results, which may encode enzymes responsible for ginsenoside backbone modification. This study provides global expressed datas for P. japonicus var. major, which will contribute significantly to further genome-wide research and analysis for this species.

Objective To investigate the distribution of water fluoride and the present status of water- improving delluoridation projects in the endemic fluorosis areas in Gansu Province. Methods According to "The National Technical Scheme for Endemic Disease Control in 2004" for the water improving projects, water fluoride content was determined from fluorosis villages in 34 counties of 11 cities in Gansu Province. The fluoride content in drinking water was assessed by F-ion selective electrode. Results Water fluoride content was determined in 1576 fluorosis villages of 34 counties. Water fluoride content of 7829 water samples was determined, and the fluoride content of 1891 samples was over standard. Water fluoride content was ≤ 1.00 mg/L(accounting for 75.19%) in 1185 villages and 1.00 mg/L(accounting for 24.81%) in 391 villages; the highest water fluoride content was 6.78 mg/L Nine hundred and ninety three water-improving and defluoridation projects were determined. Water fluoride content of 867 water-improving and defluoridation projects was determined; 768 projects had water fluoride content ≤1.00 mg/L(accounting for 87.67%) and water fluoride content of 108 projects was 1.00 mg/L(accounting for 12.33%),with the highest water fluoride content being 5.27 mg/L. Water-improving and delluoridation projects mostly relied on drilling a well to obtain under-grand water. Abandoned projects accounted for 30%. Conclusions In 34 counties of 11 cites(prefecture), nearly 30% of the villages had water fluoride content exceeding the standard. The situation of endemic fluorosis control is still serious in Gausu Province, countermeasures for endemic fluorosis must be carried out as soon as possible and surveillance of water-improving and defluoridation projects must be strengthened.
