The development of the human malaria parasite Plasmodium falciparum is controlled by coordinated changes in gene expression throughout its complex life cycle, but the corresponding regulatory mechanisms are incompletely understood. To study the relationship between genome architecture and gene regulation in Plasmodium, we used chromosome conformation capture coupled with next-generation sequencing technology (Hi-C) and generated 3D models of Plasmodium falciparum genome at three time points during its erythrocytic (asexual) cycle.
Data generated for this project
Raw reads files (fastq) and contact maps for each stage are available via GSE50199.

File: Number of MboI (restriction enzyme) cleavage sites, GC content and mappability values for each 10 kb of Plasmodium falciparum genome (PlasmoDB v9.0). Each 10 kb window is represented by its midpoint coordinate. Mappability is calculated using GEM tools with 50 basepair reads.
