A heatmap of Pearson’s correlation coefficient (PCC) between drought-responsive miRNAs (DRMs) and agronomic (in blue) and drought-tolerant (DT) (in red) traits. Five types of DRMs are at right: Type I, a miRNA is significantly correlated (|PCC| > 0.6) with at least one of measure agronomic traits; Type II, a miRNA is significantly correlated (|PCC| > 0.6) with at least one of measured DT traits; Type III, a miRNA is positively or negatively correlated with both agronomic and DT traits; Type IV, a miRNA is oppositely correlated (|PCC| > 0.6) with measured agronomic and DT traits; Type V, a pair of miRNAs are oppositely correlated (|PCC| > 0.6) with measured agronomic and DT traits
