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

摘要

Background and aimsGlandular trichomes (GT) of Artemisia annua produce valuable compounds for pharmaceutical and industrial uses, most notably the anti-malarial artemisinin. Our aim was to find out whether the density, number and size of GT can be manipulated to advantage by environmental stress. A range of external stress treatments, including stress response regulators, was therefore given to fully grown plants under field and greenhouse conditions.
