Mining the Plasmodium genome database to define organellar function: what does the apicoplast do?

Area of Science:

• Parasitology
• Genomics
• Cell Biology

Background:

• Apicomplexan parasites cause diverse diseases but share fundamental biological processes.
• Studying specific apicomplexans like Eimeria and Toxoplasma offers insights into parasite biology.
• The apicoplast, an organelle derived from secondary endosymbiosis, is crucial for parasite survival.

Purpose of the Study:

• To present the Plasmodium falciparum Genome Project as a foundational resource for apicomplexan research.
• To introduce the Plasmodium Genome Database (PlasmoDB) as a tool for investigating apicomplexan biology.
• To demonstrate the utility of PlasmoDB in identifying essential metabolic pathways within the apicoplast.

Main Methods:

• Large-scale genomic sequencing of Plasmodium falciparum.
• Development and utilization of the Plasmodium Genome Database (PlasmoDB).
• Bioinformatic analysis to identify metabolic pathways associated with the apicoplast.

Main Results:

• The first large-scale genome sequence for an apicomplexan parasite has been generated.
• PlasmoDB facilitates independent research queries into apicomplexan biology.
• Metabolic pathways within the apicoplast have been identified using PlasmoDB.

Conclusions:

• The Plasmodium falciparum genome sequence and PlasmoDB are invaluable resources for apicomplexan research.
• PlasmoDB empowers researchers to explore parasite-specific biological questions.
• Understanding apicoplast metabolic pathways is critical for targeting apicomplexan parasites.
