Quantification of M. cannonballus infection in roots of ‘Piel de sapo’ (‘PS’) plants by quantitative real-time PCR. The amount of a M. cannonballus target DNA, measured as pg per 5 ng of total genomic DNA, was used to estimate the extent of the root colonization by the fungus. Infected roots were sampled at 1, 3 and 5 days post-inoculation (DPI)
