Expression patterns of miRNAs and their target genes under drought stress. Sunflower seedling at the six leaf stages grew on soil (¾ river sand and ¼ soil) under normal conditions and leaves and roots of them were harvested as control then they treated by withholding the water for 12, 24 and 48 h. (A) Expression patterns of miRNAs in the leaf. (B) Expression patterns of miRNAs in the root. (C) Expression patterns of target gene in the leaf. (D) Expression patterns of target genes in the root.
