Validation of the target genes found for the miRNAs differentially expressed under drought.

The expression rations between drought-stressed and control plants are shown. The first number in each pair indicates miRNA levels and the second indicates the target gene expression. *indicates ratios where differences in the expression levels between irrigated and drought-stressed plants are statistically significant (P<0.05). Expression rations that are in bold indicate that miRNA induction or repression correlates with repression or induction of target genes, respectively. SAS: Sugarcane Assembled Sequence; SoGI: Sugarcane Gene Index; HT: higher tolerance cultivar; LT: lower tolerance cultivar; 2: two days of stress; 4: four days of stress.
