In response to pathogen infection, the activity of several defense-related enzymes are activated such as Superoxide dismutase (SOD), Peroxidase (POD), Catalase (CAT) responsible for scavenging reactive oxygen species (ROS) and Phenylalanine ammonia lyase (PAL) that is the key enzyme for phenylpropanoid biosynthesis (Appu et al., 2021; Song et al., 2022). The gene discussed is SOD1; the disease is infection.
