Expression changes occurring in a group of selected novel candidate miRNAs. RT-qPCR analyses are shown for n_22 (A), n_47 (B), n_55 (C), n_191 (D), n_231 (E), n_312 (F), n_327 (G), n_337 (H), n_346 (I), n_479 (J), n_520 (K), and n_622 (L) on leaf (top bars) and root (bottom bars) samples collected from CS and M4 autografted vines upon irrigated (IRR) and DS conditions. VvsnRU6 was used as the endogenous control gene for the normalization procedure. Lowercase letters above and below the bars denote significant differences (P < 0.05) attested using Tukey’s HSD test. Error bars represent se (n = 3).
