Abstract
Infection of mosquitoes by
Plasmodium spp. requires sexual differentiation of the malarial parasite in the vertebrate host and mating of the heterogametes in the vector midgut. A
Plasmodium falciparum clone, Dd2, differentiates into normal-appearing gametocytes, yet poorly infects mosquitoes. The Dd2 clone, however, effectively cross-fertilized HB3, a Central American
P. falciparum clone, and yielded several independent recombinant progeny. We have examined 11 HB3 × Dd2 progeny for their ability to infect mosquitoes and to differentiate into male gametes. Our analyses indicate that the poor mosquito-infectivity of the Dd2 clone results from a defect in male gametogenesis. This defect was inherited as a single locus in the independent recombinant progeny of HB3 × Dd2. Comparison with a restriction fragment length polymorphism map of the HB3 × Dd2 cross indicates that the defective phenotype of Dd2 maps to a locus on
P. falciparum chromosome 12. This genetic locus may contain determinants that play a crucial role in male gametogenesis by
P. falciparum.
