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 catabolism in mammalian brain [PDF]

Biochemical Journal, 1974
In contrast with putrescine (1,4-diaminobutane), which is a substrate of diamine oxidase, monoacetylputrescine is oxidatively deaminated both in vitro and in vivo by monoamine oxidase. The product of this reaction is N-acetyl-γ-aminobutyrate. The existence of a degradative pathway in mammalian brain for putrescine is shown, which comprises acetylation ...

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.

Putrescine and Acid Stress [PDF]

Plant Physiology, 1983
Incubation of peeled oat Avena sativa L. var Victory leaf segments on media of pH 5.0 or below leads to a rapid and massive increase in the titer of putrescine while incubation at pH values above 5.0 causes little or no change. The low pH effect is independent of the buffer system employed.
