Yir transcripts found in individual micromanipulated erythrocytes infected with P. yoelii at the schizont or ring/trophozoite stage of development.

1Infected erythrocyte containing schizonts with 5 or 6 nuclei (Sz) or uninucleate trophozoite (Tz).2Detected using conserved splice-site spanning primer set f1/r1 (described in Supplementary Table S3).3As determined from [22] and shown in figure 2, Groups (G) 1 to 5 and unassigned yir genes (u).4Subtelomerically located.5Unspliced (as determined by sequencing).
