Expression analysis of the PP2AB′1 promoter in AM colonized roots. Promoter GUS activity in A. rhizogenes-transformed roots expressing the PP2AB′1 promoter-β-glucuronidase fusion was assessed 4 weeks after inoculation with R. irregularis in C to F and without R. irregularis in A and B. F shows a fluorescence microscopy image of the corresponding bright-field image in E showing R. irregularis stained with wheat germ agglutinin Alexa Fluor 594, which fluoresces red. White asterisks indicate cortical cells containing arbuscules. Bars = 250 µm (A and C), 50 µm (B and D), and 20 µm (F).
