Study on the relationship between the changes in polyamine content and seedless grapes embryo rescue breeding

Frontiers in Plant Science
This study was envisaged to investigate the physiological reasons affecting the embryo development and abortion of seedless grapes on the basis of the previous embryo rescue breeding techniques of seedless grapes.

Exploring polyamines: Functions in embryo/fetal development

Animal Nutrition, 2017
Polyamines such as putrescine, spermidine, spermine and agmatine are aliphatic polycationic compounds present in all living cells, and are derived from amino acids, intestinal bacteria, exfoliated enterocytes and supported from diet.

Effects of post-translational modifications catalysed by pollen transglutaminase on the functional properties of microtubules and actin filaments [PDF]

, 2009
TGases (transglutaminases) are a class of calcium-dependent enzymes that catalyse the interactions between acyl acceptor glutamyl residues and amine donors, potentially making crosslinks between proteins.

Research on the Detoxification of Municipal Solid Waste Incineration Fly Ash: Organic Acid Washing Pretreatment Coupled With Cement/DDTC Stabilization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

Senescence and programmed cell death in plants: polyamine action mediated by transglutaminase

Frontiers in Plant Science, 2014
Research on polyamines in plants laps a long way of about 50 years and many roles have been discovered for these aliphatic cations. Polyamines regulate cell division, differentiation, organogenesis, reproduction, dormancy-break and senescence ...

Enhanced Dynamic Performance and Mechanical Reinforcement of Polyurea Coatings With Surface‐Modified Graphene Platelets

Journal of Applied Polymer Science, EarlyView.
Morphology, mechanical properties and vibration damping properties of polyurea/GNP nanocomposites. ABSTRACT Studying structural dynamics of polyurea (PU) is pivotal to analyze its vibration‐damping features. In this study, a graphene‐reinforced PU coating with enhanced mechanical and damping properties was developed.

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

The influence of chemical polyamines analogs, decarboxylated ornithine and s-(adenosyl)-methionine on the polyamine synthsis velocity in test-systems from tissues with high proliferation

RUDN Journal of Medicine, 2010
The aliphatic (amino)- and (oxy)-derivatives of polyamines effect on the rate of polyamines (Putrescine, Spermidine and Spermine) synthesis in cell-free test-systems from rat's regenerating liver and Hepatoma tissues was examined.

Putrescine alleviates cold injury in peach fruit via elevating the conjugated polyamines in tonoplast and thereby maintaining vacuole conformation

Horticultural Science
Exogenous polyamines can elevate postharvest fruit cold resistance and alleviate cold injury. However, the mechanism, by which polyamines mediate cold tolerance, is still to be explored.
