Polyamine treatments: an effective strategy to improve crop yield and fruit colour and to preserve quality of ‘Mollar de Elche’ pomegranate fruit during storage at chilling temperatures

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change in Spain is altering the optimal conditions for producing high‐quality ‘Mollar de Elche’ pomegranate fruit, due to reduced colour development in husk and arils. In addition, the pomegranate requires storage above 7–10 °C, depending on cultivar, to preserve its quality because it is susceptible to chilling injury (CI ...

Main effects of ascorbic acid levels and organic acid type on physicochemical properties, microbial populations, texture, and biogenic amine formation in sucuk

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Sucuk is a traditional Turkish dry fermented sausage, the quality and safety of which depend on physicochemical, microbiological, and biochemical changes during fermentation and ripening. Organic acids, their salts, and antioxidants such as ascorbic acid (AA) are widely used in fermented meat products; however, information about ...

Polyamine stress at high pH in Escherichia coli K-12

BMC Microbiology, 2005
Background Polyamines such as spermine and spermidine are required for growth of Escherichia coli; they interact with nucleic acids, and they bind to ribosomes. Polyamines block porins and decrease membrane permeability, activities that may protect cells

Haploid Mutation Mapping Identifies a Homoeologous Non‐Reciprocal Translocation Linked to Reduced Fibre and Enhanced Protein in Brassica napus

Plant Biotechnology Journal, EarlyView.
ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, EarlyView.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Spermine binding to liver mitochondria

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1996
Non-equilibrium binding of spermine to mitochondrial membranes is studied in rat liver mitochondria by applying a new thermodynamic treatment of ligand-receptor interactions (Di Noto, V., Dalla Via, L., Toninello, A. and Vidali, M. (1996) Macromol. Theory Simul. 5, 165-181).
