Under fusarium infection conditions, treatment with A. fumigatus recorded 3 faints bands at Rf (0.204, 0.629 and 0.786) and 1 moderate band at Rf (0.786), while Rhizopus oryzae treatment gave a high expression of PPO resulted in 1 moderate bands at Rf (0.204), 1 faint bands at Rf (0.786), and 1 highly dense band at Rf (0.629). Here, PPOX is linked to fusariosis.
