Outline of Final Research Achievements

Detailed mutational trend of a mutator malaria parasite possessing proofreading deficient DNA polymerase δ was analyzed. The mutation spectrum was biased, and the base substitution of the parasite was influenced by sequence context. By using the mutator parasite, chloroquine resistant parasites were successfully generated. DNA sequencing analysis of genes involved in genome replication and/or stability with global Plasmodium falciparum DNA samples was also conducted, and fundamental information on the genetic polymorphism was obtained.
