Cloned(Commentary)

Cloned (Comment) Organism
overexpression of PAO in transgenic Nicotiana tabacum plants leading to dramatically increased expression levels of Mpao and high 1,3-diaminopropane content in the tobacco plant leaves, stems, and roots Zea mays
transgenic tobacco plants overexpressing polyamine oxidase from Zea mays exhibit high 1,3-diaminopropane content Zea mays

Protein Variants

Protein Variants Comment Organism
additional information transgenic Mpao overexpressing tobacco plants show highly increased enzyme activity and 1,3-diaminopropane levels, also specific isoforms of the antioxidant machinery, i.e. peroxidase, superoxide dismutase and catalase, are induced in the transgenics but not in the wild-type, along with increase in activities of additional enzymes contributing to redox homeostasis. Nevertheless, further increase in the intracellular reactive oxygen species by exogenous H2O2, or addition of methylviologen or menadione to transgenic leaf discs, results in oxidative stress as evidenced by the lower quantum yield of PSII, the higher ion leakage, lipid peroxidation and induction of programmed cell death, overview Zea mays
