The standard error (SE) was calculated for median values, with p < 0.1.
*
The values for up-regulated (UP) profiles were significantly different from the control group when the expression profile during water stress diverged from the control at 10% probability (p < 0.1) upon randomization testing (n = 2,000 iterations). All statistical analyses were done using RESTmsc software.
