FIGURE 3

XTH expression profile in excised segment extracts of (A) the first 5 mm of the root apical region and (B) the root sub-apical region of 3-day-old wheat seedlings (cultivar Simeto, Creso, and Ardente) subjected to drought stress for 2 and 4 h. XTH expression is reported as decrease in transcript level (log2 fold change) with respect to time 0 (control). Data are the mean ± standard deviation of three independent replicates (n = 3).
