Effect of Putrescine Treatment on Chilling Injury, Fatty Acid Composition and Antioxidant System in Kiwifruit. [PDF]

PLoS ONE, 2016
We investigated the effects of different concentrations (0, 1, 2 and 4 mM) of putrescine on chilling injury, fruit quality, ethylene production rate, fatty acid composition and the antioxidant system of cold-stored kiwifruit (Actinidia chinensis Planch ...

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.

Alarmone ppGpp modulates bacterial motility, zeamine production, and virulence of Dickeya oryzae through the regulation of and cooperation with the putrescine signaling mechanism

mSphere
Putrescine is an important interspecies and interkingdom communication signal, modulating the bacterial motility, biofilm formation, and virulence of D. oryzae. The understanding of the regulation of putrescine biosynthesis and transport in D.

Effects of Spermidine on Cell Proliferation, Migration, and Inflammatory Response in Porcine Enterocytes

Frontiers in Bioscience-Landmark, 2022
Background: Polyamines have been demonstrated to be beneficial to porcine intestinal development. Our previous study showed that putrescine mitigates intestinal atrophy in weanling piglets and suppresses inflammatory response in porcine intestinal ...

The Smell of Death: Evidence that Putrescine Elicits Threat Management Mechanisms

Frontiers in Psychology, 2015
The ability to detect and respond to chemosensory threat cues in the environment plays a vital role in survival across species. However, little is known about which chemical compounds can act as olfactory threat signals in humans.

Putrescine Upregulates Melanogenesis Through Modulation of MITF Transcription Factor in B16F1 Mouse Melanoma Cells

Food Technology and Biotechnology
Research background. Ageing is a biochemical, metabolic and genetic physiological phenomenon. The suppression of melanin biosynthesis, evident in the greying of the hair, is a hallmark of ageing resulting from translation failure, reduced enzyme activity

Effect of mycorrhizal fungi and foliar application of putrescine on some biochemical characteristics and biomass of basil (Ocimum ciliatum L.) in two different harvesting times [PDF]

فیزیولوژی محیطی گیاهی, 2019
In order to investigate the effect of mycorrhizal fungi and foliar application of putrescine on some biochemical characteristics, essential oil content, and biomass of basil (Ocimumciliatum L.), a split plot in time experiment with three replications was

Metagenomic and biogenic amine changes in cassava fermentation for tucupi production using Pediococcus acidilactici starter culture. [PDF]

J Sci Food Agric
Abstract BACKGROUND The use of starter cultures is essential for producing fermented foods with desirable standardized characteristics and for preventing pathogens. Pediococcus acidilactici, isolated from cocoa fermentation, was used in the production of tucupi, a widely appreciated sauce made from the juice of cassava root (manipueira) in the ...

Discovery of H2 Receptor Antagonists as Colistin Enhancers by Targeting Acid Stress Response

Advanced Science, EarlyView.
This study identifies YqgB as a key target for restoring colistin susceptibility in mcr‐positive pathogens under acidic conditions by remodeling phospholipid composition and reducing LPS modification. Deep learning‐based screening reveals H2 receptor antagonists as novel colistin adjuvants. Further investigations indicate that ranitidine and famotidine

Effect of foliar treatment of putrescine on growth and flowering of annual gypsophila (Gypsophila elegance)

The Indian Journal of Agricultural Sciences, 2023
In this research work, we attempted to know the positive response of putrescine on plant growth and flowering of annual flower gypsophila. Putrescine is important because it has been shown that exogenous treatment can enhance the production or ...
