Polyamines are low molecular weight amines that serve numerous pivotal functions in
eukaryotic cells, such as contributing to processes like embryogenesis, organogenesis in …

The diamine putrescine, the triamine spermidine and the tetraamine spermine are
ubiquitous in plant cells. They occur in free form as cations and are often conjugated to small …

Polyamines are low molecular weight amines, with versatile and essential functions during
the lifespan of prokaryotes and eukaryotes. Modulation of polyamine metabolism under …

Polyamines (PAs) are ubiquitous amine molecules found in all living organisms. In plants,
beside their role in signaling and protection against abiotic stresses, there is increasing …

Polyamines are essential metabolites found in all organisms. Intracellular polyamine levels
are tightly maintained by biosynthesis, degradation, uptake and excretion processes that …

This chapter describes polyamine synthesis and catabolism in plants, and discusses the role
of polyamines in the interactions between plants and their pathogens (fungi, viruses …

The diamine putrescine and the polyamines spermidine and spermine are found in a wide
range of organisms from bacteria to plants and animals. They are basic, small molecules …

Polyamines (PAs) are positively charged amines such as putrescine, spermidine and
spermine that ubiquitously exist in all organisms. They have been considered as a new type …

During ontogeny, plants interact with a wide variety of microorganisms. The association with
mutualistic microbes results in benefits for the plant. By contrast, pathogens may cause a …

Although most work on polyamines in incompatible interactions between plants and
pathogens has focussed on polyamines conjugated to phenolic compounds …
