Polyamines (PAs) are low molecular weight aliphatic nitrogenous bases containing two or
more amino groups. They are produced by organisms during metabolism and are present in …

Compelling evidence indicates that free polyamines (PAs)(mainly putrescine, spermidine,
spermine, and its isomer thermospermine), some PA conjugates to hydroxycinnamic acids …

It is presently unclear how much individual community members contribute to the overall
metabolic output of a gut microbiota. To address this question, we used the honey bee …

As one of the most important crops in the world, rice (Oryza sativa) is a model plant for
metabolome research. Although many studies have focused on the analysis of specific …

Plants produce a variety of metabolites that have a critical role in growth and development.
Here we present a comprehensive study of maize metabolism, combining genetic …

Being by far the largest family of enzymes to support plant metabolism, the cytochrome
P450s (CYPs) constitute an excellent reporter of metabolism architecture and evolution. The …

Significance of naturally occurring intracellular polyamines (PAs), such as spermine,
spermidine, and putrescine, in relation to the mechanism and adaptation to combat abiotic …

Floral chemistry mediates plant interactions with pollinators, pathogens, and herbivores, with
major consequences for fitness of both plants and flower visitors. The outcome of such …

Plants are built of various specialized cell types that differ in their cell wall composition and
structure. The cell walls of certain tissues (xylem, sclerenchyma) are characterized by the …

Polyamines are amine-containing, low molecular weight, and ubiquitous polycationic
molecules present in almost all cells and free-living microbes, which are formed by aliphatic …
