Variation of photosynthesis,secondary metabolites and antioxidant activities in third generation of spaceflight-induced Salvia miltiorrhiza
文献摘要：
Objective:Spaceflight has long been perceived as an effective way to improve the quantity and quality of plants with wide applications.In order to obtain stable and inheritable descendants of spaceflight-induced Salvia miltiorrhiza lines,we investigated and analyzed four lines m16,m50,m51,m57(three individuals of each line)and the ground control(three individuals)of the third generation of spaceflight-induced S.miltiorrhiza from primary/secondary metabolism and antioxidative abilities.Methods:A portable photosynthesis system(Li-6400)with red/blue LED light source was used to perform the photosynthetic characteristics to evaluate their primary productivity.The secondary metabolites(phenolic acids,tanshinones,total phenolics and flavonoids)and antioxidant activity of roots were ana-lyzed to assess their quality.Results:Compared with control,line m1 6 presented weak photosynthetic ability,but high apparent quantum yield(AQY),higher contents of secondary metabolites,and stronger antioxidative abilities.Line m57 had a strong gas exchange ability,relatively higher secondary metabolites contents,and ascending antioxidative abilities.Lines m50 and m51 were in the middle level of lines m16 and m57.The principal component analysis for all the original data revealed three components including a root-related index,a leaf-related index,and a CO2 response parameter could be used to distinguish spaceflight-induced S.miltiorrhiza lines.Conclusion:Line m57 could be an appropriate material for the investigation of targeted breeding towards high production,and line m1 6 could be used to identify essential genes and unravel sophisticated path-ways underlying the secondary metabolisms.
