| Popis: | Atractylodes macrocephala Koidz. (AM), an herb of traditional Chinese medicine, is well-known for anti-oxidant, anti-tumor and immune regulation potential. However, it is low bioactive compound content that restricts the application of this species. Elicitation is considered as an effective method to enhance biomass and bioactive compound in plants. Our precious study found that polysaccharide of Chrysanthemun indicum L. could promote plant growth by triggering plant defense. In the present study, polysaccharide of Chrysanthemun indicum L. is used to stimulate the accumulation of biomass and bioactive compound with different concentration in Atractylodes macrocephala Koidz. during pot, plot and field experiments. The results suggested that polysaccharide of Chrysanthemun indicum L. could significantly enhance the accumulation of biomass, atractylenolides and polysacchrides. Moreover, 2 mg/mL is determined and verified to be the appropriate concentration during field experiments. In addition, RT-qPCR revealed that CIP-induced terpenoid synthesis in AM mainly depended on mevalonate (MVA) pathway. This is the first report on the discovery of polysaccharide of Chrysanthemun indicum L. for the enhanced accumulation of biaomass and bioactive compound and the use of its for agricultural production. |
