Benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH) can improve wound healing of potato tubers; however, how the chemical regulates reactive oxygen species (ROS) generation and scavenging during wound healing is not completely understood. BTH at 100 mg·L−1 regulated changes in ROS generation and scavenging in healing tissues of potato tubers. A higher H2O2 content was presented in healing tissues of potato tubers, while cell membrane permeability and malondialdehyde content declined due to BTH treatment. Additionally, the activities and transcript level of enzymes related with ROS generation, including NADPH oxidase, peroxidase and polyamine oxidase, as well as enzymes involved in ROS scavenging, such as superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase, were significantly enhanced by BTH treatment. It is suggested that ROS metabolism might play a crucial role in wound healing of potato tubers mediated by BTH during postharvest. © 2019 Elsevier Ltd
