Effect of the Combination of the Growth Regulators and Putrescine on the Somatic Embryogenesis of Wheat (Triticum Aestivum L.) on Some Types of Explants

open access: yesJournal of Applied Agricultural Science and Technology, 2023
Plant breeding programs need to be carried out in order to improve the genetics of wheat that is able to adapt to tropical environments through hybridization, mutation induction, tissue culture, and genetic transformation.

Changing root system architecture through inhibition of putrescine and feruloyl putrescine accumulation [PDF]

open access: yesFEBS Letters, 1994
Plant roots provide anchorage and absorb the water and minerals necessary for photosynthesis in the aerial parts of the plant. Since plants are sessile organisms, their root systems must forage for resources in heterogeneous soils through differential branching and elongation [(1988) Funct. Ecol. 2, 345‐351; (1991) Plant Roots: The Hidden Half, pp.

EVALUATION OF THE EFFECT OF EXOGENOUS PUTRESCINE DURING THE MATURATION AND GERMINATION in vitro OF SOMATIC EMBRYOS IN TWO AGAVE GENOTYPES

open access: yesTropical and Subtropical Agroecosystems, 2023
Background. Agaves are an important economic source in industrial products, in the food and pharmaceutical industry, steroidal animal feed, ornamental plants and as a material for biofuels. Despite their economic importance, some species present problems

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

open access: yes, 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 ...

Spectrofluorometric Determination of Putrescine: Optimization of the Putrescine–Orthophthaldehyde Complex Using Spectrofluorometry

open access: yesJournal of AOAC INTERNATIONAL, 2016
Abstract In alkaline medium, the complex formed between putrescine and orthophthalaldehyde was studied using spectrofluorescence. The derivative is kinetically stable 24 h after complexation. The stoichiometry of the complex is 1:1 at maximum fluorescence intensity, also 24 h after complexation.

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

open access: yesPLoS 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 ...

Regulation of Macromolecular Synthesis by Putrescine in a Conditional Escherichia coli Putrescine Auxotroph [PDF]

open access: yesJournal of Bacteriology, 1972
Addition of putrescine to a slowly growing, polyamine-starved Escherichia coli K-12 mutant conditionally incapable of synthesizing putrescine causes the immediate stimulation of protein synthesis. After a period ranging from 60 to 105 min, ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) syntheses are also ...

Wine Putrescine Abatement by Bentonites: From Ideal Case to Practice [PDF]

open access: yes, 2023
Herein, we demonstrated that bentonites can be incisively used to reduce wine BAs content, especially putrescine molecules. Pioneering kinetic and thermodynamic studies of putrescine adsorption onto two commercially available bentonites (optimal ...

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

open access: yesFood 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
