Figure 4. Mycorrhizal phenotype in oscerk2, oscerk2;oscerk1, oscerk1, and osccamk. (A–B) Trypan blue staining of (A) WT (Pii), oscerk1, oscerk2, and oscerk2;oscerk1 and (B) WT (+/+) and osccamk inoculated with R. irregularis and incubated for 2 weeks and 5 weeks. Scale bars=100 mm. ab, arbuscles; ih, internal hypha; eh, external hypha; hp, hyphopodia; v, vesicles. (C) The number of infection units/plants in WT, oscerk1, oscerk2, oscerk2;oscerk1, WT (+/+), and osccamk at 2 WAI. (D) Root length colonization ratio in WT, oscerk1, oscerk2, oscerk2;oscerk1, WT(+/+), and osccamk at 5 WAI.
