Validation of the DEGs by RT-qPCR.

<p>The relative expression levels of ten unigenes, which exhibited the ‘up-up-down’ expression pattern in the course of 24h of water stress following 6h of rehydration, were calculated with the 2^–ΔΔCT method. The <i>actin</i> gene was used as an internal control. For each tested unigene, the columns from left to right represented its relative expressive levels in P-0h, P-6h, P-24h and Rh-6h, respectively. Error bars indicated the standard deviation of the mean expression values.
