Additionally, nanomaterials with CAT-like activity containing individual transition metals usually have poor bactericidal activity, which may be insufficient for the effective prevention and control of plant bacterial diseases.49 To address these limitations, it has important implications for controlling kiwifruit canker disease to develop novel multifunctional nanocomposites with both high antibacterial activity and ROS scavenging effect. The gene discussed is CAT; the disease is bacterial infectious disease.
