Figure 4

RNA integrity of untreated, DNase treated and DNase/ethanol precipitated RNA samples from CRD and cambial zone tissue. RNA integrity number (left) and a representative Bioanalyzer electropherogram (right) is shown for each treatment. (A) Untreated, (B) DNase treated, (C) DNase treated and ethanol precipitated RNA samples. Error bars represent standard error of three biological replicates. The dotted line in untreated samples (A) represents a region of genomic DNA background contamination that is removed by DNase treatment (B and C). RIN: RNA integrity number; FU: Fluorescence units.
