摘要:

为筛选适宜当归(Angelica sinensis)悬浮细胞生长和主要活性物质积累的茉莉酸甲酯(MeJA)浓度,将当归悬浮细胞在含不同浓度(CK、25、50、100、150、200 μmol⋅L-1)MeJA液体培养基中培养,9 d后测定细胞生长量、主要活性物质含量、体外抗氧化能力、阿魏酸和黄酮类化合物生物合成相关基因表达水平。结果表明:较低浓度(25 μmol⋅L-1)MeJA促进细胞生长,高浓度MeJA显著抑制细胞生长。随MeJA浓度增加,主要活性物质(阿魏酸、可溶性糖、总黄酮和总酚)含量显著升高,体外抗氧化能力呈显著增强趋势,在高浓度150~200 μmol⋅L-1下其趋于稳定或降低。相对于CK,低浓度MeJA促进阿魏酸生物合成相关基因(PAL2、4CLL6、HCT4等)表达,高浓度MeJA抑制该基因表达;但高浓度MeJA促进黄酮类生物合成相关基因(CHS2、CHI2、F3H-3等)表达。本研究结果可为利用诱导子调控当归悬浮细胞生长和代谢产物积累提供参考。

Abstract:

To screen an optimal methyl jasmonate (MeJA) concentration suitable for growth and primary bioactive metabolite accumulation of Angelica sinensis suspension cells, the cell biomass, primary bioactive metabolite contents, in vitro antioxidant activities, and expression levels of genes related to ferulic acid and flavonoids biosynthesis were measured to the suspension cells inoculated into the liquid medium containing different concentrations of MeJA(CK, 25, 50, 100, 150, and 200 μmol⋅L-1) for 9 days. The results showed that the cell growth was enhanced at a lower concentration of MeJA(25 μmol⋅L-1) while inhibited at higher concentrations. The contents of primary bioactive metabolites (ferulic acid, soluble sugar, total flavonoids and phenolic) and in vitro antioxidant activities showed increasing trends with an increase in MeJA concentration, while the values tended to stabilize or decrease at the higher MeJA concentrations(150-200 μmol⋅L-1). Compared with CK, the expression levels of genes(e.g., PAL2, 4CLL6, and HCT4) related to ferulic acid biosynthesis were enhanced at lower concentrations of MeJA and inhibited at higher concentrations; whereas the expression levels of genes(e.g., CHS2, CHI2, and F3H-3) related to flavonoids biosynthesis were enhanced at the higher MeJA concentrations. These findings provide references for regulating suspension cell growth and metabolite accumulation of A. sinensis by using elicitors.

Key words: Angelica sinensis, methyl jasmonate, suspension cell growth, bioactive metabolite accumulation, gene expression
