From: GmPAO-mediated polyamine catabolism enhances soybean Phytophthora resistance without growth penalty
A proposed model illustrating the mechanism of GmPAO-mediated resistance. The two substrates Spd and Spm are increased upon P. sojae infection. GmPAO-mediated Spd/Spm catabolism enhances H2O2 production and PTI activation, thereby controlling the infection caused by P. sojae. The activation of PTI response might promote the increase of Spd and Spm contents in soybean
