Annual wormwood (Artemisia annua L.) produces an array of complex terpenoids including artemisinin, a compound of current interest in the treatment of drug-resistant malaria. However, this promising antimalarial compound remains expensive and is hardly available on the global scale. Synthesis of artemisinin has not been proved to be feasible commercially. Therefore, increase in yield of naturally occurring artemisinin is an important area of investigation. The effects of inoculation by two… 

Negative effects of artemisinin on phosphorus solubilizing bacteria in vitro.

Potential Ecological Roles of Artemisinin Produced by Artemisia annua L.

Evidence of the potential utility of artemisinin in protecting the plant from insects and other herbivores, as well as pathogens and competing plant species is discussed, and new data is provided on the toxicity of art Artemisinin towards soil and aquatic organisms.

Strategies for Enhancing Artemisinin Production in Artemisia annua Under Changing Environment

Using pot and field experiments, some PGRs and radiation-processed polysaccharides proved as non-conventional elicitors that enhanced the overall yield of artemisinin under normal and abiotic stress conditions.

Mutualistic and Endophytic Microorganisms of Artemisia Annua: Description, Role and Use

The purpose of this paper is to draw attention to the current status of the research on mutualistic and endophytic microorganism of A. annua that have the potential to increase the quality and quantity of the crude drugs, derived from the herb.

Dual symbiosis between Piriformospora indica and Azotobacter chroococcum enhances the artemisinin content in Artemisia annua L.

The study suggested the potential use of the consortium P. indica strain DSM 11827 and A. chroococcum strain W-5 in A. annua L. plants for increased overall productivity and sustainable agriculture.

Impact of Phosphatic Nutrition on Growth Parameters and Artemisinin Production in Artemisia annua Plants Inoculated or Not with Funneliformis mosseae

Artemisia annua L. is a medicinal plant appreciated for the production of artemisinin, a molecule used for malaria treatment. However, the natural concentration of artemisinin in planta is low. Plant

Effect of Mineral Nutrition, Growth Regulators and Environmental Stresses on Biomass Production and Artemisinin Concentration of Artemisia annua L.

The present chapter is reviewing the various factors that affect biomass and artemisinin production of A. annua, the only commercial source of artemis inin, a rare sesquiterpene lactone that is the only safe alternative therapy against multi-drug-resistant malaria.



Arbuscular mycorrhiza alter the concentration of essential oils in oregano (Origanum sp., Lamiaceae)

It is concluded that the EO increase observed in mycorrhizal oregano plants is not due to an improved P status in my corollary plants, but depends directly on the AMF–oregano plant association.

Attenuation of cadmium toxicity in mycorrhizal celery (Apium graveolens L.)

The dilution effect due to increased biomass, immobilization of Cd2+ in root and enhanced P-uptake in M plants may be related to attenuation of C d2+toxicity in celery.

Glomus macrocarpum: a potential bioinoculant to improve essential oil quality and concentration in Dill (Anethum graveolens L.) and Carum (Trachyspermum ammi (Linn.) Sprague)

AM fungal inoculation in general improved the growth of the plants and increased the concentration of essential oil in Anethum graveolens L. and Trachyspermum ammi (Linn.) Sprague fruits.

Effect of triacontanol and chlormequat on growth, plant hormones and artemisinin yield in Artemisia annua L.

Artemisinin and herbage yield of Artemisia annua plants were determined after application of triacontanol (tria.) and chlormequat (2-chloroethyltrimethylammonium chloride). Tria. at 1.0 and 1.5 mgl−1

State of the art of the production of the antimalarial compound artemisinin in plants

The state of art of the different aspects in A. annua research is reviewed, which includes whether to overproduce artemisinin or one of its precursors.

Nitrogen supply affects arbuscular mycorrhizal colonization of Artemisia vulgaris in a phosphate-polluted field site.

It is suggested that N deficiency stimulates root colonization by AMF in this extraordinarily P-rich field site.

Effects of arbuscular mycorrhiza and phosphorus application on arsenic toxicity in sunflower (Helianthus annuus L.) and on the transformation of arsenic in the rhizosphere

AM inoculation alleviated the effects of As toxicity by improving P nutrition without increasing As concentrations in the shoots, and appeared to be involved in the transformation of soil inorganic As into less toxic organic forms.

Influence of arbuscular mycorrhizal fungi and salinity on growth, biomass, and mineral nutrition of Acacia auriculiformis

Great nutrient acquisition, changes in root morphology, and electrical conductivity of soil in response to AM colonization was observed, and may be possible mechanisms to protect plants from salt stress.

Effects of three AM fungi on growth, distribution of glandular hairs, and essential oil production in Ocimum basilicum L. var. Genovese

Results showed that different fungi can induce different effects in the same plant and that the essential oil yield can be modulated according to the colonizing AM fungus.

Growth responses and dependence of Acacia nilotica var. cupriciformis on the indigenous arbuscular mycorrhizal consortium of a marginal wasteland soil

A sharp and considerable reduction in MD and dry matter yield observed at 40’ppm P suggests that the external P requirement for maximal production of biomass was met at approximately 20 ppm Olsen-P.
