Foliar application of putrescine alleviates terminal drought stress by modulating water status, membrane stability, and yield- related traits in wheat (Triticum aestivum L.)

Frontiers in Plant Science, 2023
Drought stress is one of the major limitations to the growth and yield productivity of cereal crops. It severely impairs the early growing and grain -filling stages of wheat.

Putrescine mitigates intestinal atrophy through suppressing inflammatory response in weanling piglets

Journal of Animal Science and Biotechnology, 2019
Background Polyamines are essential for cell growth and beneficial for intestinal maturation. To evaluate the effects of putrescine on alleviating intestinal atrophy and underlying molecular mechanisms, both in vivo feeding trial and in vitro cell ...

Increased Uptake of Putrescine in the Rhizosphere Inhibits Competitive Root Colonization by Pseudomonas fluorescens Strain WCS365

Molecular Plant-Microbe Interactions, 2001
Sequence analysis of the chromosomal Tn5lacZ flanking regions of the Pseudomonas fluorescens WCS365 competitive root colonization mutant PCL1206 showed that the Tn5lacZ is inserted between genes homologous to bioA and potF.

Conformational Stabilization of Rat S-Adenosylmethionine Decarboxylase by Putrescine [PDF]

, 2010
The activity and processing of mammalian S-adenosylmethionine decarboxylase (AdoMetDC) is stimulated by putrescine. To obtain new insights into the mechanism through which putrescine stimulates AdoMetDC, we investigated conformational changes in rat ...
