摘要： To elucidate the metabolic mechanism of Ascorbic Acid (ASA) in the CMS-pepper anthers, the metabolism changes in the reactive oxygen species (ROS) contents, antioxidants contents and ROS scavenging enzymatic activities were investigated in the anther mitochondria of CMS-9704A and maintainer-9704B. At the abortion stage, anthers of CMS-9704A had higher contents of ROS than those of the maintainer. Simultaneously, there were lower contents of ASA and glutathione (GSH) in stage 2 and 3, and the lower activities of ascorbate peroxidase (APX) and glutathione perodixase (GPX) in stage 3 in scavenging ROS in the anthers of the CMS line than maintainer. The expression level of APX and GPX in stage 3 in anthers of CMS-9704A was obviously inhibited when ROS produced with a great deal during anther stage; however the gene expression kept normal in the maintainer. Excessive accumulation of ROS, significant reduction activities and gene expression level of ROS-scavenging enzyme were coinstantaneous with CMS.
