General Information

General Information Comment Organism
physiological function ascorbate oxidase catalyzes the oxidation of ascorbate to yield water. Enzyme overexpressing plants are prone to ozone and salt stresses, whereas lower expression apparently confers resistance to unfavorable environmental conditions. High enzme expression is viewed as a possible strategy to down-regulate oxygen diffusion in root nodules, and a component of arbuscular mycorrhizal symbiosis. Key role of this gene/enzyme in both nodule and arbuscular mycorrhizal development and functioning. The enzyme might be part of the general mechanism regulating cell wall architecture Lotus japonicus
