Figure 1.

Mycorrhizal parameters of Oryza sativa Nipponbare wild type rice plants compared to brd2-1 mutant plants defective in BR biosynthesis 6 weeks after inoculation with Rhizophagus irregularis. F%: infection frequency, M%: absolute mycorrhizal colonization, m% relative mycorrhizal colonization, A% absolute arbuscule abundance, a% relative arbuscular abundance. Shown are mean values and standard deviations. Significant differences between WT and brd2-1 mutant plants are indicated by asterisks (Students-t-test, P ≤ 0.05; n = 4-6).
