Expression of GFP protein in transgenic Arabidopsis thaliana roots. A Arabidopsis thaliana roots of 4 stable transgenic events were observed and photographed under a fluorescence microscope in not inoculated (mock) or inoculated (inoc) at 9 days with Meloidogyne javanica. Green fluorescence indicates expression from the promoter and induction of the GFP marker. a PGmHsp22.4–3 inoc. b PGmHsp22.4–4 inoc. c PGmHsp22.4–6 inoc. d PGmHsp22.4–12 inoc. e PGmHsp22.4–3 mock. f PGmHsp22.4–4 mock. g PGmHsp22.4–6 mock. h PGmHsp22.4–12 mock. B Quantification of the levels of green fluorescence of the four events of transgenic Arabidopsis thaliana, analyzed by the Adobe® Photoshop® CS6 13.0 × 32 software program. The data shown are representative of three biological replicates for each condition (inoc and mock). * indicates statistical significance at the 5% level (Scheffé’s -test) compared to the mock control
