A Plasmodium knowlesi A1-H.1 transcriptome time course focusing on the late asexual blood stages.

A first transcriptome time course for Plasmodium knowlesi A1-H.1 across five intraerythrocytic developmental cycle stages shows strong genome-wide conservation of temporal expression versus Plasmodium vivax orthologues.

• Why it matters: A lack of stage-resolved expression data for P. knowlesi limits comparative studies that use it as an experimental model for P. vivax biology.
• What they did: Bulk RNA-sequencing was performed at five tightly synchronized IDC stages in human normocytes to define constitutively expressed genes, stage-specific biomarkers, and temporal patterns across multigene families.
• The result: Conserved expression patterns in invasion-associated genes and ApiAP2 transcription factors, plus an open-access orthologue expression webtool, enable rapid identification of candidate P. vivax genes for functional study using P. knowlesi A1-H.1.
