Polyamines are naturally occurring aliphatic compounds, particularly essential elements for
biological functions. These compounds play a central role in regulating molecular pathways …

In this review we will concentrate in the results published the last years regarding the
involvement of polyamines in the plant responses to abiotic stresses, most remarkably on …

Plants are challenged by a variety of biotic or abiotic stresses, which can affect their growth
and development, productivity, and geographic distribution. In order to survive adverse …

Polyamines are polycations that interact with negatively charged molecules such as DNA,
RNA and proteins. They play multiple roles in cell growth, survival and proliferation …

Polyamines are universal organic polycations implicated in a wide array of fundamental
processes in plants ranging from triggering the cell cycle, genome expression, signaling …

Polycationic polyamines are present in nearly all living organisms and are essential for
mammalian cell growth and survival, and for development. These positively charged …

A highly oxidative stress-tolerant japonica rice line was isolated by T-DNA insertion mutation
followed by screening in the presence of 50 mM H 2 O 2. The T-DNA insertion was mapped …

Polyamines are small organic polycations that are absolutely required for cell growth and
proliferation; yet the basis for this requirement is mostly unknown. Here, we combined a …

The polyamines spermidine and spermine are positively charged aliphatic molecules. They
are critical in the regulation of nucleic acid and protein structures, protein synthesis, protein …
