The early observation of the different steps in the infection process is in concordance with previous studies concerning pathogenic Rhizoctonia AGs on several hosts [9,18,31,32] and the faster and more abundant stomatal penetration of the AG 1-1B and AG 1-1C isolates is probably correlated with the aerial nature of these AGs [33], since isolates from foliage have been reported to penetrate stomata more frequently [10]. Here, JAG1 is linked to infection.
