Understanding how genetic variation in malaria parasites is structured acro
ss populations has benefits for researchers interested in finding loci that
affect the ability of the parasite to resist host immunity or drugs. In a
recent paper, Tim Anderson and colleagues have provided a broad-scale analy
sis of Plasmodium falciparum population structure. Their results provide an
indication of the feasibility of using population-genetic and genetic-mapp
ing approaches to pinpoint selected loci, in addition to reconciling some p
reviously disparate views of population structure in malaria.
