Functions of amine oxidases in plant development and defence
چکیده انگلیسی

Copper amine oxidases and flavin-containing amine oxidases catalyse the oxidative de-amination of polyamines, which are ubiquitous compounds essential for cell growth and proliferation. Far from being only a means of degrading cellular polyamines and, thus, contributing to polyamine homeostasis, amine oxidases participate in important physiological processes through their reaction products. In plants, the production of hydrogen peroxide (H2O2) deriving from polyamine oxidation has been correlated with cell wall maturation and lignification during development as well as with wound-healing and cell wall reinforcement during pathogen invasion. As a signal molecule, H2O2 derived from polyamine oxidation mediates cell death, the hypersensitive response and the expression of defence genes. Furthermore, aminoaldehydes and 1,3-diaminopropane from polyamine oxidation are involved in secondary metabolite synthesis and abiotic stress tolerance.
