Fig. 2From: Crystal structure of DRIK1, a stress-responsive receptor-like pseudokinase, reveals the molecular basis for the absence of ATP bindingZmDRIK1 expression is downregulated under drought stress. B73 maize plants were grown in pots with soil for 13, 10 or 8 days after which watering was stopped for 9, 12 or 14 days (days of stress), respectively. Half of the stress-treated plants were sampled and immediately immersed in liquid nitrogen and stored at − 80 °C. The other half of the stress-treated plants (marked with *), were rewatered for 24 h and then sampled. Results are average ± standard deviation (three biological replicates) of relative mRNA content of ZmDRIK1 in leaves of maize plants, submitted to drought-stress and rewatering treatments. The gene EIF4a was used for expression normalization. At alpha 0.05 level, the relative mRNA level of ZmDRIK1 in drought-stressed leaves was significatively lower than its level in leaves of rewatered plants, with the same period of treatment. The p-values of Student’s t test between treatments are indicated above the comparative lines in the figureBack to article page
