To confirm the expression of identified genes in vascular tissues, probes that specifically bind the mRNA of a small number of the identifed genes were applied to switchgrass tissue. The darker regions indicate the vascular bundles where the probes bound the abundant mRNA from the active expression of targeted genes in these regions.
