   1.10.3.3 | malfunction |
a diminution in ascorbate oxidase activity affects carbon allocation and improves yield in tomato under water deficit, overview. RNAi knockout plants show increased fruit yield under three conditions where assimilate became limiting for wild-type plants: when fruit trusses are left unpruned, when leaves are removed or when water supply is limited. Several alterations in the transgenic lines can contribute to the improved yield and favour transport of assimilate from leaves to fruits in the ascorbate oxidase lines. RNAi lines show altered sink strength |

AAO belongs to the large family of multicopper oxidases. AAO labelling in the cytosol, walls and chloroplasts of Chaetomorpha linum cells, whereas in angiosperms this enzyme is almost exclusively confined to the extracellular matrix, possible function of AAO in adaptation and functional evolution of its cellular location, overview |

| 1.10.3.3 | 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 |
