Ascorbate peroxidase (APX) is a reactive oxygen species (ROSs) scavenging enzyme involved in regulation of intracellular ROS levels by reduction of H(2)O(2) to water using ascorbate as an electron donor. In New Phytologist 2007; 175:462-71, we identified a cotton cytosolic APX1 (GhAPX1) that was significantly accumulated during the fast fiber-cell elongation period, through a proteomics approach. Both the transcript levels of GhAPX1 and the total APX activity were highly induced in response to… CONTINUE READING
