Fig. 7From: The NAD kinase OsNADK1 affects the intracellular redox balance and enhances the tolerance of rice to droughtRelative expression levels of several genes that may be related to OsNADK1 expression in the wild-type (WT, cv. Dongjin) and osnadk1 mutant under normal growth and drought stress conditions. Four-week-old plants were used for the drought treatment. The gene symbols and primer sequences used for qRT-PCR are listed in Additional file 8: Table S3. Control, watering normally; drought, without watering for 10 days. 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
