^aRNA samples were isolated from callus cultures during the linear phase of growth (20–22 d). Two RNA samples were analyzed with three analytical repetitions. 

^bDashes indicate the absence of expression. The data are presented as mean ± se. * P < 0.05 versus values of the control cultures, ANOVA followed by Fisher's Plsd test.
