Figure 4

Transverse sections through roots of maize, 15 days after infection with S. hermonthica. (A and B) show cross sections of a wild type maize root (A) and a transgenic hairy root (B) infected with S. hermonthica (embedded in Technovit resin). C and D show a bright field and UV fluorescence image, respectively, of a cross section through a frozen hairy root infected with S. hermonthica. The parasite has traversed the root cortex and formed connections with the host xylem vessels. (E and F) show cross sections of a wild type maize root infected with S. hermonthica under bright field and UV irradiance. En, endophyte (internal part of haustorium); Hc, host root cortex; He, host endodermis; Hx, host xylem; Hx–Px, host–parasite xylem continuity; Hy, hyaline body; P, parasite haustorium; and Px, parasite xylem vessels.
