Effect of external stress on density and size of glandular trichomes in full-grown Artemisia annua, the source of anti-malarial artemisinin

Glandular trichomes (GT) on Artemisia annua produce and store the anti-malarial compound artemisinin (AN) and other secondary metabolites (SM) that have several pharmaceutical and industrial uses. This paper investigates the spatial and temporal distribution of GT on leaves and tests the hypotheses that environmental stress influences the size and density of GT.
