Control of gene expression in Plasmodium falciparum - ten years on

Ten years ago this journal published a review with an almost identical title detailing how the then recent introduction of transfection technology had advanced our understanding of the molecular control of transcriptional processes in Plasmodium falciparum, particularly in terms of promoter structure and function. In the succeeding years, sequencing of several Plasmodium spp. genomes and application of high throughput global postgenomic technologies have proven as significant, if not more, as has the ability to genetically manipulate these parasites in dissecting the molecular control of gene expression. Here we aim to review our current understanding of the control of gene expression in P. falciparum, including evidence available from other Plasmodium spp. and apicomplexan parasites. Specifically, however, we will address the current polarised debate regarding the level at which control is mediated, and attempt to identify some of the challenges this field faces in the next 10 years.
