Abstract excerpt

POLYAMINE OXIDASE 1 (OsPAO1), from rice (Oryza sativa), and POLYAMINE OXIDASE 5 (AtPAO5), from Arabidopsis (Arabidopsis thaliana), are enzymes sharing high identity at the amino acid level and with similar characteristics, such as polyamine specificity and pH preference; furthermore, both proteins localize to the cytosol. A loss-of-function Arabidopsis mutant, Atpao5-2, was hypersensitive to low doses of...
