The abundance of water deficit-responsive miRNAs and the abundance of the target transcripts they regulate under mild and severe water deficit stress. Abundance is presented as the log [2] FC in transcript abundance under water deficit stress relative to well-watered conditions. Red indicates a significant increase in target transcript or miRNA abundance under water deficit stress, green indicates a significant decrease in abundance (FDR < 0.05). Gray values were not statistically significant. a The predicted target transcript of the water deficit-responsive miRNA was not differentially regulated under any water deficit stress. b Water deficit-induced regulation of predicted regulatory miRNA is positively correlated with the regulation of the target transcript. c Water deficit-induced regulation of predicted regulatory miRNA is inversely correlated with the regulation of the target transcript
