Table 1. Epigenetic differentiation between leaf and flower tissue of Brassica rapa R-o-18 plants after herbivory and MeJA treatment.
| Pair-wise AMOVA of meth. markers | Control Flower | Control Leaf | Herbivory Flower | Herbivory Leaf | MeJA Flower |
|---|---|---|---|---|---|
| Control Leaf | F = 0.21 P<0.0001 | ||||
| Herbivory Flower | F = 0.02 P = 0.0007 | F = 0.24 P<0.0001 | |||
| Herbivory Leaf | F = 0.31 P<0.0001 | F = 0.06 P = 0.0244 | F = 0.34 P<0.0001 | ||
| MeJA Flower | F = 0.02 P = 0.0008 | F = 0.19 P<0.0001 | F = 0.03 P = 0.0006 | F = 0.31 P<0.0001 | |
| MeJA Leaf | F = 0.38 P<0.0001 | F = 0.11 P = 0.0044 | F = 0.38 P<0.0001 | F = 0.03 P = 0.1153 | F = 0.37 P<0.0001 |
| Global AMOVA of meth. markers | Deg. of freedom among groups | Deg. of freedom within groups | Variance among groups | Variance within groups | F-value |

F- and P-values for global and pair-wise AMOVA of methylation-susceptible loci from different tissues (leaves and flowers) of control-, herbivory-, and MeJA-treated plants show a larger epigenetic differentiation between the tissues, and a smaller but still significant epigenetic differentiation between the different treatments except for leaves of herbivory- and MeJA-treated plants. P value of significant differentiations in bold (α = 0.05).
