FIGURE 8.
The effect of 3,4-DHP on the localization of JIM11 epitope during symbiotic seed germination of D. officinale. (A) After 3 weeks of inoculation, most embryos did not enlarge, and weak signals of JIM11 epitope (arrow) are observed in the walls of basal end of the embryo. Scale bar = 50 μm. (B) After 3 weeks of inoculation, the infected embryo showing weak signals of JIM11 epitope (arrow) in the walls of basal end of the swollen embryo. Scale bar = 50 μm. (C) Most seeds in the treatment with 3,4-DHP are unable to germinate, and the severe fungal invasion in the ungerminated seeds could be commonly observed. Scale bar = 50 μm.
