The suppression on chitin-induced ROS accumulation from PbrChiA depend on PbrLYK1b2 In our previous results, the resistant variety R-532 displayed a decreasing trend in ROS levels and related enzyme activities at later stages of infection, similar to the phenotype observed in PbrChiA-OE Arabidopsis and pear callus, and the PbrChiA-interacting protein PbrLYK1b2 positive regulates the ROS-related immune response.
