RESUMO

Metabolomics, a branch of systems biology, has gained extensive attention and profound achievements in the plant. Although plant metabolomics is to be explored, it has been one of the most effective methods to study the physiological and biochemical process and gene modification in pattern plants. We herein summarized the concept, development, and application of metabolomics and prospected the potentials in the metabolite profiling for plant. Metabolomics provides an omics' methodology to elucidate the whole biological process, identify and quantify the complex components in the plant. A number of metabolites present in the plant are active components of traditional Chinese medicine, and these bioactive components are influenced by the multi-factors such as environment, species, and processing methods etc. Therefore, it is of great importance to analyze a wide spectrum of compositions with diverse chemical characteristics and varied concentration, which is the foundation to quality control, allowing the elucidation of the pharmacological effectiveness, and further exploiting of traditional Chinese medicine.

RESUMO

<p><b>OBJECTIVE</b>To investigate the induction and culture of adventitious root of Panax notoginseng.</p><p><b>METHOD</b>Three ways, induction from the explants of three-year-old P. notoginseng. The explants of regenerated shoots and calluses, were used to induce adventitious roots. The effects of 2, 4-dichlorophenoxyacetic acid, indole-3-butyric acid and naphthylacetic acid on adventitious root induction were investigated respectively. The effects of four modes of separating adventitious roots from the parent tissues on culture in vitro were compared.</p><p><b>RESULT</b>Adventitious roots were successfully induced by three methods, of which the young flower bud callus was the best material for the induction of adventitious root. Indole-3-butyric acid possessed the strongest potency for induction. The liquid culture system was established by continuous culture of adventitious roots together with their parent tissues before separated.</p><p><b>CONCLUSION</b>The acquisition and culture in vitro in liquid culture system of adventitious roots of P. notoginseng lay a foundation for the next investigation.</p>
