Application of Bioinformatics and Systems Biology in Medicinal Plant Studies / 中草药·英文版

One important purpose to investigate medicinal plants is to understand genes and enzymes that govern the biological metabolic process to produce bioactive compounds.Genome wide high throughput technologies such as genomics,transcriptomics,proteomics and metabolomics can help reach that goal.Such technologies can produce a vast amount of data which desperately need bioinformatics and systems biology to process,manage,distribute and understand these data.By dealing with theomicsdata,bioinformatics and systems biology can also help improve the quality of traditional medicinal materials,develop new approaches for the classification and authentication of medicinal plants,identify new active compounds,and cultivate medicinal plant species that tolerate harsh environmental conditions.In this review,the application of bioinformatics and systems biology in medicinal plants is briefly introduced.

Studies on the Activation of Germination of the Seeds of Chinese Thorowax (Bupleurum chinense)and Sandochaihu(B. falcatum)by Exogenous Hormones / 中草药

Germination of the seeds of Bupleurum chinense and B. falcatum activated by exogenous hormones of dif ferent concentrations was studied. The hormones used were GA3, 6-BA and IAA. The optimum concentration of the 3 hormones that activated the seed germination of B. chinense was 50?g/ml,while that for B. falcatum was 200?g/ml, 100?g/ml and 25?g/ml respectively. Among the 3 hormones, 6-BA showed the greatest effect on the 2 species of Bupleurum L. 50?g/ml 6-BA raised the germination rate of the seeds of B. chinese from 57.5 % to 84. 5 % and 100?g/ml 6-BA raised the germination rate of the seeds of B.falcatum from 28. 5 % to 76.0%
