  1. Experimental data was collected from two sources: (1) Pathogen-Host Interaction database (PHI-base) [40] and (2) the work of Jeon et al. [41]. Phenotype: based on mutant deviations in conidiation and appressorium formation compared to untransformed control. Effector: gene product or signaling molecule resulting from its enzymatic activity that triggers defensive mechanisms in the plant host. Hence, effectors are usually known as avirulence determinants.
