FIGURE 1.

GUS-stained Brachypodium distachyon stem cross sections from 37-day-old plants transformed with the BdPMT (first column), BdCESA7 (second column), and BdCESA8prom::GUSPlus (third column) constructs. Wild type (WT) control sections are shown in the fourth column. Sections for a given line were from the same culm. All sections were stained the same duration so as to show relative expression levels. Pictured on the left is a culm with its internodes (I) labeled along with the locations from which each section was taken. B = base and M = middle of internode. Scale bar for sections = 170 μm.
