Fig. 9From: The NAD kinase OsNADK1 affects the intracellular redox balance and enhances the tolerance of rice to droughtRelative expression levels of genes in transgenic plants detected by qRT-PCR. The gene symbols and primer sequences used for qRT-PCR are listed in Additional file 8: Table S3. Data are means±SD from three independent biological replicates. Bars annotated with different letters represent values that were significantly different by the Tukey method (p ≤ 0.05)Back to article page
