Figure 6

Illustration of the structures of a healthy specimen along the depth direction and structural differences according to the progress of the disease infection. The enface images were obtained from the corresponding depth levels of 250 μm, 500 μm, and 1000 μm, from each specimen. The dashed yellow-colored circle depicts the formation and the spread of circular tissue patterns in infected regions. Vertical and horizontal scale bars, 500 μm.
