Elevated production of reactive oxygen species is related to host plant resistance to sugarcane aphid in sorghum.

ABSTRACT: Sugarcane aphid (Melanaphis sacchari) is a phloem-feeding insect that severely affects the growth and productivity of sorghum and other related crops. While a growing body of knowledge is accumulating regarding plant, and insect interactions, the role of reactive oxygen species (ROS) against aphid infestation in sorghum has not been established yet. Here, the involvement of H₂O₂ and ROS detoxification enzymes in host plant resistance to sugarcane aphid in sorghum was demonstrated. The H₂O₂ accumulation and expression patterns of selected ROS scavenging enzymes including ascorbate peroxidase (APX), glutathione S transferase (GST), superoxide dismutase (SOD), and catalase (CAT) in response to sugarcane aphid infes
