Overexpression of Allene Oxide Cyclase Improves the Biosynthesis of Artemisinin in Artemisia annua L.
Jasmonates (JAs) are important signaling molecules in plants and play crucial roles in stress responses, secondary metabolites' regulation, plant growth and development. In this study, the promoter of AaAOC, which was the key gene of jasmonate biosynthetic pathway, had been cloned. GUS staining showed that AaAOC was expressed ubiquitiously in A. annua. AaAOC gene was overexpressed under control...
متن کاملRNAi down-regulation of cinnamate-4-hydroxylase increases artemisinin biosynthesis in Artemisia annua
Cinnamate-4-hydroxylase (C4H) converts trans-cinnamic acid (CA) to p-coumaric acid (COA) in the phenylpropanoid/lignin biosynthesis pathway. Earlier we reported increased expression of AaCYP71AV1 (an important gene of artemisinin biosynthesis pathway) caused by CA treatment in Artemisia annua. Hence, AaC4H gene was identified, cloned, characterized and silenced in A. annua with the assumption t...
متن کاملThe biosynthesis of artemisinin (Qinghaosu) and the phytochemistry of Artemisia annua L. (Qinghao).
The Chinese medicinal plant Artemisia annua L. (Qinghao) is the only known source of the sesquiterpene artemisinin (Qinghaosu), which is used in the treatment of malaria. Artemisinin is a highly oxygenated sesquiterpene, containing a unique 1,2,4-trioxane ring structure, which is responsible for the antimalarial activity of this natural product. The phytochemistry of A. annua is dominated by bo...
متن کاملArtemisia annua L
Shoot cultures of Artemisia annua L. were cultivated in three different micropropagation systems: an ultrasonic nutrient mist bioreactor (UNMB), a modified ultrasonic nutrient mist bioreactor (MUNMB) and solid culture in Magenta boxes. The shoots cultivated in the UNMB and MUNMB showed excellent growth. The dry weight increase (35 times) of shoot cultures in the MUNMB was higher than those (25 ...
متن کاملArtemisia annua (Sweet Annie), Other Artemisia Species, Artemisinin, Artemisinin Derivatives, and Malaria
This paper reviews the use of whole-plant Artemisia annua (sweet Annie) as it pertains to malaria including history, chemistry, clinical efficacy, pharmacokinetics, dosing, safety, and resistance. Artemisinin, the sesquiterpene lactone found in the plant, and various semi-synthetic variants of it used as critical drugs around the world for malaria are discussed in comparison to the whole plant....
