Promoter activity of ARK1 in R. irregularis colonized roots. a GUS staining in cortical cells of R. irregularis colonized (Myc) pARK1:GUS roots containing arbuscules (numbered 1–8) but not in nonarbusculated cells at 6 weeks post-inoculation. b Wheat germ agglutinin (WGA)-Alexa Fluor 488-stained root sector from (a) showing intercellular hyphae and arbuscules (numbered 1–8). c Mock-inoculated (MI) control pARK1:GUS  root lacks GUS staining. d Cross-section of inoculated pArk1:GUS and empty vector (EV) control (e) roots shows GUS staining exclusively in arbuscule-containing cells. Scale bar 100 μm (a, b), 50 μm (c), 10 μm (d, e). Representative images of three roots from five replicate plants are provided
