Plant pathogens, and photosynthesis inhibiting herbicides, can both damage photosystem II (PSII), causing it to be highly sensitive to damage by light energy, and to release high levels of reactive oxygen species (ROS). This photoinhibition of PSII could possibly be the source of the strong oxidative burst associated with the pathogeninduced, hypersensitive defense response (HR). To examine a possible mechanism of how the HR-associated ROS burst could originate from PSII inhibition, we compared the transcriptome responses in soybean undergoing photoinhibition induced by HR, to soybean undergoing photoinhibition induced by the herbicide bentazon, which specially stops PSII electron flow by preventing QB from binding to D1. Most genes shared similar expression patterns between HR and bentazon treatments; however, interesting differences were also observed. The most stri.. View More»
