Callus cultures of Arnebia euchroma (Royle) Johnst can produce considerable amounts of shikonin derivatives, which are shown to possess a wide spectrum of pharmaceutical properties, such as antimicrobial, anticancer, antioxidative, immune regulative and anti-inflammatory. To explore the possible regulation mechanism of shikonin derivatives biosynthesis, the effects of ammonium ion (NH4+) on cell growth...
Artemisia annua L. is the only commercial source of the widely used antimalarial compound artemisinin. Biosynthesis of artemisinin has been proposed to take place in glandular trichomes. The first committed step in the conversion of farnesyl diphosphate (FDP) to artemisinin is conducted by the amorpha-4,11-diene synthase (ADS). To explore the organ-specific and developmental distributions of ADS,...
This paper provides evidence that salicylic acid (SA) can activate artemisinin biosynthesis in Artemisia annua L. Exogenous application of SA to A. annua leaves was followed by a burst of reactive oxygen species (ROS) and the conversion of dihydroartemisinic acid into artemisinin. In the 24 h after application, SA application led to a gradual increase in the expression of the 3-hydroxy-3-methylglutaryl...
A type III polyketide synthase cDNA and the corresponding gene (PcPKS2) were cloned from Polygonum cuspidatum Sieb. et Zucc. Sequencing results showed that the ORF of PcPKS2 was interrupted by three introns, which was an unexpected finding because all type III PKS genes studied so far contained only one intron at a conserved site in flowering plants, except for an Antirrhinum majus chalcone synthase...
