چکیده
|
In the present study the effect of rare earth element praseodymium (pr) on flavonoids production and its biosynthesis key enzymes including peroxidase (pod; ec 1.11.1.7),polyphenol oxidase (ppo; ec 1.10.3.1) and phenylanlanine ammonialyase (pal; ec 4.3.1.5) in hairy roots of scutellaria viscidula was investigated. after 7 days of suspension culture,activity of pod,ppo and pal and total flavonoid production showed the same response tendency,which was ascending first and then descending with the pr3+ elicitor increasing,and the pr(no3)3 concentration reaching the knee point was 15,25,25,25,25,ordinarily. subsequently mechanism of flavonoids accumulation by pr elicitation at the biochemical level is very significant for application of rare earth element to large scale production of plant nature drugs.
