Project description:We sought to determine the transcriptomic impacts of artemisinin, Artemisia annua extract, and Artemisia afra extract on M. tuberculosis. Log phase cultures were treated with lethal doses for four hours or with inhibitory or sub-inhibitory doses for 24 hours. RNA was collected from untreated controls at the same timepoint.
Project description:Artemisia annua is known to produce the antimalarial phytomolecule artemisinin. The seedling and mature leaf of the plant represent two contrasting tissues in terms of their artemisinin content. The major objective of the present study was to use a small-scale (750 target genes) microarray of A. annua for identification of genes that are differentially expressed in the seedling and mature leaf tissues of the plant.
