Arbuscular mycorrhizal phenotype of P. vulgaris PvTOR-RNAi roots colonized by R. irregularis. (A) The arbuscules in the cortex cells of the control transgenic roots are well developed. (B–C) Stunted arbuscules in the cortex cells of the PvTOR-RNAi transgenic roots at 1 wpi and 3 wpi, respectively. (D) Quantification of stunted arbuscules per transgenic control and PvTOR-RNAi roots at 3 wpi. The statistical significance of differences between control and PvTOR-RNAi roots was determined using an unpaired two-tailed Student’s t-test (***P < 0.001). Error bars refer to the SD of the mean of three biological replicates (n > 30 for D). a, arbuscule; ih, intercellular hyphae; sa, stunted arbuscule, iah, intracellular hyphae; wpi, week(s) post inoculation, Ri, R. irregularis.
