Confocal scanning laser microscopic images showing Foc1 progression and colonization in roots of JG62 plants.

(A–C) corresponds to root sections of uninduced plants. (D–F) represent root sections of JG62 plants after 4dpi; (G–I) after 7dpi; (J–L) after 7dpi (magnified view); (M–O) after 12dpi; (P–R) after 12dpi (magnified view). (A, D, G, J, M, P) represents fluorescent images. (B, E, H, K, N, Q) represents differential interference contrast (DIC) images. (C, F, I, L, O, R) represents merged images. Bars represent 20 µm.
