a
Nodules and their designations, A or B, are as shown in Figure 2. Zone numbers indicate which zones were present in the part of the nodule that was reconstructed. I, Meristem; II, infection zone; II-III, interzone II-III.
b
Dimensions of the smallest rectangular volume that included all of the ITs in the reconstructed dataset (e.g. the volume of the meristem is not included because it did not contain ITs).
