Evolution of malaria parasite plastid targeting sequences.
The transfer of genes from an endosymbiont to its host typically requires acquisition of targeting signals by the gene product to ensure its return to the endosymbiont for function. Many hundreds of plastid-derived genes must have acquired transit peptides for successful relocation to the nucleus. Here, we explore potential evolutionary origins of plastid transit peptides in the malaria parasit...
متن کاملPotent in vivo anti-malaria activity of Goniothalamin against rodent malaria parasite infection in mice
Goniothalamin was evaluated for its anti-malaria activity in-vivo, using the 4-Day Suppressive Test (Peters & Robinson, 1975). The test were carried out against two strains of rodent malaria parasites, the sensitive strain P. berghei ANKA (MRA 311) strain and the resistant strain P. yoelii (MRA 312). An Initial screening was carried out using a single dose of 10 mg/kg body weight administered s...

متن کاملCompensatory evolution in the human malaria parasite Plasmodium ovale.
The fixation of neutral compensatory mutations in a population depends on the effective population size of the species, which can fluctuate dramatically within a few generations, the mutation rate, and the selection intensity associated with the individual mutations. We observe compensatory mutations and intermediate states in populations of the malaria parasite Plasmodium ovale. The appearance...
متن کاملTest tube evolution catches time in a bottle.
For most living things, 24,000 generations is a daunting span of time. Go back that many human generations, or about 500,000 years, and Homo sapiens had not yet evolved. Even for the fruit flies beloved of geneticists, 24,000 generations equals about 1500 years. But in Richard Lenski's laboratory at Michigan State University in East Lansing, 24,000 generations ago is a recent memory. The year w...
