Abstract: This paper briefly reviews the catabolic pathway of polyamine degradation in higher plants; the characteristics of enzymes involved, such as polyamine oxidases, diamine oxidases, aminopropyl transferase, g-aminobutyric acid transaminase, and succinic semialdehyde dehydrogenase; and the physiological roles of its main catabolic products such as diaminopropane, g-aminobutyric acid, uncommon polyamines, and hydrogen peroxide.

Key words: g-aminobutyric acid, Diaminopropane, Polyamine catabolism, Polyamine oxidases, Hydrogen peroxide
