摘要: Salicylic acid (SA) is a critical signal for activation of both local and systemic resistance responses. However, SA-deficient plants adapt to RNA virus infections better, which show less-severe symptom less reactive oxygen species (ROS) accumulation. The higher levels reduced glutathione (GSH) ascorbic (AsA) in may contribute their alleviated symptoms, are consistent with expression dehydroascorbate reductase gene (DHAR) (GR). High-dose AsA or GSH treatment could alleviate the inhibit replication after 20 days, but ROS eliminators not imitate effect GSH. data new link between SA AsA/GSH-mediated redox homeostasis.
