This review focuses on the intricate relationship between plant polyamines and the genetic
circuits and signaling pathways that regulate various developmental programs and the …

Alkaloids from plants are characterised by structural diversity and bioactivity, and maintain a
privileged position in both modern and traditional medicines. In recent years, there have …

Abiotic stresses collectively are responsible for crop losses worldwide. Among various
abiotic stresses, drought and salinity are the most destructive. Different strategies have been …

Background Human gut bacteria can synthesize proteinogenic amino acids and produce a
range of metabolites via protein fermentation, some known to exert beneficial or harmful …

Spermidine is a natural polyamine that has health benefits and extends life span in several
species. Deoxyhypusine synthase (DHPS) and deoxyhypusine hydroxylase (DOHH) are key …

Early studies on plant polyamine research pointed to their involvement in responses to
different environmental stresses. During the last few years, genetic, transcriptomic and …

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

Polyamines are primordial polycations found in most cells and perform different functions in
different organisms. Although polyamines are mainly known for their essential roles in cell …

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

Polyamines (PAs) are ubiquitous biogenic amines that have been implicated in diverse
cellular functions in widely distributed organisms. In plants, mutant and transgenic plants …
