Fig. 1From: Two COWP-like cysteine rich proteins from Eimeria nieschulzi (coccidia, apicomplexa) are expressed during sporulation and involved in the sporocyst wall formationSchematic drawing of the arrangements and content of expression cassette. EnOWP reporter cassettes are head-to-head orientated to the chimeric selectable marker (dhfr/ts-yfp) Etact5′: E. tenella actin promoter, dhfr/tsm2m3: encodes a pyrimethamine resistant dihydrofolate reductase-thymidilate synthase [25], yfp: yellow fluorescent protein; 3′: 3′flanking region of E.tenella actin gene. Construct 1: pEnOWP2pro-mC encodes the chimeric selectable marker and a mCherry gene under control of the EnOWP2-promoter; Construct 2: pEnOWP2-mC encodes the chimeric selectable marker and a mCherry gene fused to the full length genomic EnOWP2 controlled by the authentic promoter. Construct 3: pEnOWP2Exon1-mC encodes the chimeric selectable marker and a mCherry gene fused with the Exon1 of EnOWP2 controlled by the authentic promoter; Construct 4: pEnOWP6-mC encodes the chimeric selectable marker and a mCherry gene fused to the full length genomic EnOWP6 controlled by the authentic promoterBack to article page
