Pathogenicity was attenuated in PsBZP32-silenced transformants. a Etiolated seedlings of the susceptible soybean cultivar Hefeng47 were inoculated with zoospores of the WT and PsBZP32-silenced transformants and photographed at 36 hpi. b ROS accumulation in hypocotyls inoculated with zoospores of P. sojae (WT and PsBZP32-silenced transformant T14 as examples) at 12 hpi by DAB staining. Red arrows indicate infected hyphae. Bar, 50 μm
