Centromeric Plasmids and Artificial Chromosomes: New Kids on the Plasmodium Transfection Block

In this issue of Cell Host & Microbe, Iwanaga and colleagues (Iwanaga et al., 2010) report on the construction of plasmids and artificial chromosomes that are stably maintained throughout the Plasmodium life cycle. These new tools will have multiple applications, from episome-based genetic strategies to studies on telomere biology and antigenic variation
