Mutant/mutation
The mutants expresses GFP under control of the constitutive eef1a promoter and OVA (ovalbumin) under control of the constitutive eef1a promoter. The gfp- and ova-expression cassettes are introduced on a Plasmodium artificial chromosome (PAC)

PyNL-GFP-OVA was generated using a PAC as described by Iwanaga et al (2010, Cell Host & Microbe 7, 245-255) . The following elements were inserted into the PAC: 1) elongation factor promoter; 2) green fluorescence protein (GFP); 3) Pb hsp70 3'-untranslated region; 4) P. berghei (Pb) pyrimethamine resistant gene dihydrofolate reductase-thymidyltransferase-ts (DHFR-ts) gene; 5) Pb DHFR-ts 3'-untranslated region and 6) GFP-OVA, cytosolic form without the ovalbumin (OVA) signal sequence open reading frame.

In the paper no details are provided on (the generation of) the PAC such as centromeric (and telomeric regions; P. berghei or P. yoelii sequences?); circular or linear PAC. In addition no primer sequences (and gene IDs) are provided for amplification of the different regulatory sequences used or for OVA.

The PAC used has been introduced as a circular PAC containing the P. yoelii chromosome 5 centromeric region.
