Figure 3From: Screening for plant transporter function by expressing a normalized Arabidopsis full-length cDNA library in Xenopus oocytesEffect of different UTRs on gene expression in Xenopus oocytes. CDSs of AtSTP1, AtSTP4, AtSTP13, AtSUCI, and AtSUC2 were expressed with their native plant UTRs or with Xenopus-specific β-globin gene UTRs. Water injected oocytes functioned as negative controls for endogenous glucose or sucrose uptake by oocytes. Assays were performed with 15 μM radio labelled glucose or sucrose (~100 μCi/μmol).Back to article page
