The P. falciparum 3D7 nuclear genome is composed of 22.8 megabases (Mb) distributed among 14 chromosomes ranging in size from approximately 0.643 to 3.29 Mb (Fig. 1, and Supplementary Figs AâN). Thus the P. falciparum genome is almost twice the size of the genome of the fission yeast Schizosaccharomyces pombe.
Parasites of the genus Plasmodium cause malaria. Although there are many species of Plasmodium, only five infect humans and cause malaria. P. falciparum: found in tropical and subtropical areas; major contributor to deaths from severe malaria. P. vivax: found in Asia and Latin America; has a dormant stage that can cause relapses. P. ovale: found in Africa and the Pacific islands. P. malariae: worldwide; can cause a chronic infection.
