Polyamines have long been implicated in plant adaptation to abiotic and biotic stress. As a
general rule of thumb the higher the polyamine titers the better. However, their molecular …

Polyamines (PAs) have been considered as important molecules for survival. However,
evidence reinforces that PAs are also implicated, directly or indirectly, in pathways regulating …

Glutamate dehydrogenase (GDH) may be a stress-responsive enzyme, as GDH exhibits
considerable thermal stability, and de novo synthesis of the α-GDH subunit is induced by …

Polyamines (PAs) exert a protective effect against stress challenges, but their molecular role
in this remains speculative. In order to detect the signaling role of apoplastic PA-derived …

In contrast to animals, where polyamine (PA) catabolism efficiently converts spermine (Spm)
to putrescine (Put), plants have been considered to possess a PA catabolic pathway …

Spermidine (Spd) has been correlated with various physiological and developmental
processes in plants, including pollen tube growth. In this work, we show that Spd induces an …

Polyamine oxidases (PAOs) are FAD-dependent enzymes involved in polyamine catabolism.
All so far characterized PAOs from monocotyledonous plants, such as the apoplastic maize …

Polyamine (PA) titers and biosynthesis follow a basipetal decrease along the tobacco (Nicotiana
tabacum) plant axis, and they also correlate negatively with cell size. On the contrary, …

Polyamines (PAs) have been suggested to be implicated in plant responses to abiotic and
biotic stress. Grapevine is a model perennial plant species whose cultivars respond differently …

We previously gave a picture of the homeostatic characteristics of polyamine (PA) biosynthesis
and conjugation in tobacco (Nicotiana tabacum) plant organs during development. In this …
