Figure 3.
miRNA accumulation within the vasculature and meristem is tuned at the post-transcriptional level: (A) miR166; (B) miR167; (C) miR156; (D) miR160; (E) miR319; (F) miR394. (A–F) In situ hybridization patterns of developmentally relevant mature miRNAs in the maize apex (left) generally correspond well to the expression profiles of the corresponding precursors (right), with the notable exception that miR160 (D), miR319 (E), and miR394 (F) are not detected in the meristem despite prominent precursor expression in those domains.
