Figure 2: Differential regulation of VvMAP kinase cDNA under water deficiency. (a) Identical amounts of RNAs were denaturated by glyoxylation and subjected to electrophoresis on 1.2% agarose gels. Transcript abundance was evaluated in the leaves material of Razegui cultivar. Each lane contained 10 μg of total leaf RNA. C: control, S: 3 weeks of water deficiency. (b) 26 S RNA gene used as an internal control for equal loading.
