Quantitative real-time PCR (qRT-PCR) gene expression analysis of the OsSUT-gene family in paired samples of leaf blade, leaf sheath and root from individuals of Oryza sativa cv. Taipei 309, Nipponbare and Pokkali at stage V8-V10. Samples were harvested 12 days after exposure to 75 mM NaCl (black) or a respective mock treatment (white). Data represent the mean of E−ΔΔCt values calculated using the geometric mean of the Ct values from four housekeeping genes (n = 5 plants). Note that the expression of the OsSUT3- and OsSUT5-genes was below the limits of qRT-PCR quantification. Percentages indicate significant (p < 0.05) salt induced reduction of expression relative to control levels.
