miRNA quantitative expression. Expression levels of selected artichoke miRNAs by means of qPCR in leaves (a) and roots (b) under control (black bar, arbitrarily set to 1) and NaCl stress (colored bars) conditions. Expression levels are given as fold change of stressed versus control tissues. Asterisks indicate significance at a p value of < 0.05. Bars refer to standard error.
