Global metabolic profiling of Arabidopsis Polyamine Oxidase 4 (AtPAO4) loss-of-function mutants exhibiting delayed dark-induced senescence

Early and more recent studies have suggested that some polyamines (PAs), and particularly spermine (Spm), exhibit anti-senescence properties in plants. In this work, we have investigated the role of Arabidopsis Polyamine Oxidase 4 (PAO4), encoding a PA back-conversion oxidase, during dark-induced se...
