Protein elicitor AMEP412 suppressed rice blast caused by Magnaporthe Oryzae through triggering plant immunity (PRJCA042041)
AMEP412 is a protein elicitor secreted by Bacillus subtilis, exhibiting the ability to trigger plant immunity. This study assessed how AMEP412 induced the disease resistance of rice seedling against rice blast caused by Magnaporthe oryzae. Firstly, the pathogen inoculation assay confirmed that AMEP412 pretreatment significantly reduced the lesion areas on rice leaves. Then the inner reactions of rice seedlings responding to protein eliciting and pathogen infection were analyzed, respectively. After AMEP412 pretreatment, early defense response was successfully triggered in rice leaves, including obvious accumulation of reactive oxygen species (ROS) and activity increase of antioxidant enzymes (SOD, CAT, and POD).
