Table 1. Percent silenced area with different fractions of CD-5KDifferent fractions of the CD-5K preparation were formulated with the *GFP*-targeting 22-mer siRNA at a concentration of 8 ng μL^{−1}. The mean percent silenced area relative to the entire leaf area was calculated digitally with four replicates per treatment. Means were separated using a Student’s *t* test. The fractions not connected by a letter are statistically different (α = 0.05). Images used for the analysis are included in Supplemental Fig. S5.
