Additional file 7: Figure S7. of The sucrose non-fermenting 1-related kinase 2 gene SAPK9 improves drought tolerance and grain yield in rice by modulating cellular osmotic potential, stomatal closure and stress-responsive gene expression

The relative expression level of SAPK9 gene in reproductive stage (panicle initiation) was analysed through real-time PCR from leaf tissues of three sets of plants, i.e. OE, RNAi and NT plants. For internal reference, rice polyubiquitin1 (OsUbi1) gene was used. Error bars represent the mean ± SD of triplicate measurements. Student’s t-test was performed to find out statistically significant differences (**P < 0.01). (TIF 240 kb)
