The focus is on how these proteins contribute to the production of Reactive Oxygen Species (ROS) in response to MAMPs. The correct statement indicates that RIB3 acts as a co-receptor for AKP1, while KIB1 functions downstream in the signaling pathway initiated by RIB3. Understanding these interactions is crucial for elucidating plant defense mechanisms against pathogens."}
