   1.2.3.4 | metabolism |
the enzyme is capable of stimulating the ester-linked diferulic acid formation. The enzyme is capable of modifying the metabolism of ester-linked ferulates in cell walls of wheat shoots by promoting the peroxidase action via supply of hydrogen peroxide |

| 1.2.3.4 | metabolism |
trans-MnIII(salophen)(OH2)2+ and bioxalate (HOX-)in aqueous medium equilibrate rapidly to trans-MnIII(salophen)(OH2)(HOX) followed by the acid dissociation equilibrium to the (aqua)monooxalato complex. The slow redox reactions of trans-MnIII(salophen)(OH2)(HOX/OX)0/- with H2OX, HOX-, OX2-obey second order kinetics satisfying 2:1 stoichiometry. The products are MnII and CO2. The sequence of the redox activity of the oxalato complexes reflects the potential role of noncovalent interaction i.e. H-bonding, governing the proton controlled electron transfer process |

| 1.2.3.4 | physiological function |
expression of barley oxalate oxidase gene confers stable resistance against stem rot in productive and highly susceptible Brassica juncea cv Varuna under field conditions. Stable, single-copy transgenic lines exhibit a significant reduction in the rate of lesion expansion reproducibly over the three-generation i.e. T2, T3, and T4 respectively. The enhanced resistance in the transgenic lines correlated with high oxalate oxidase activity, accumulation of higher levels of H2O2, and robust activation of defense responsive genes upon infection by Sclerotinia sclerotiorum |

| 1.2.3.4 | physiological function |
oxalate oxidases OXO2, OsOXO3 and OsOXO4 positively regulate panicle blast resistance in rice. The OXO genes can modulate the accumulation of H2O2 and expression levels of pathogenesis-related gene in plants. The OXO genes-mediated panicle blast resistance can be regulated by abscisic acid, salicylic acid and jasmonic acid, and may be associated with the activation of jasmonic acid and abscisic acid signaling pathways but suppression of the salicylic acid signaling pathway |

| 1.2.3.4 | physiological function |
the enzyme is involved in the senescence of coleoptiles in rice by catalyzing the oxidation of oxalate |
726212 |
| 1.2.3.4 | physiological function |
the enzyme is not a disease resistance factor in rice. since transgenic rice plants with substantially higher enzyme activity are not more resistant to rice blast and bacterial blight than the wild type |
741281 |
| 1.2.3.4 | physiological function |
transgenic Arabidopsis lines that express the enzyme exhibit enhanced resistance to oxalate exposure and Sclerotinia sclerotiorum infection |

| 1.2.3.4 | physiological function |
transgenic soybean plants overexpressing an oxalate oxidase gene from wheat show enhanced resistance to sclerotina stem rot. They display significantly reduced lesion sizes, i.e. by 58.71-82.73% reduction of lesion length in a detached stem assay (T3 and T4 generations) and 76.67-82.0% reduction of lesion area in a detached leaf assay (T4 generation). The transgenic plants also show increased tolerance to the externally applied oxalic acid (60 mM) relative to the controls. Decreased oxalic acid content and increased hydrogen peroxide (H2O2) levels are also observed in the transgenic leaves after Scerotina sclerotiorum inoculation |
