The market of ready-to-eat leafy green salads is experiencing a noticeable growth in Europe. Since they are intended to be consumed without additional treatments, these products associated with high microbiological risk. aim this work was evaluate the quality and safety sold widespread supermarket chains Lazio, Italy, on packaging date during shelf-life home-refrigeration. study also aimed determine differences between low-, medium-, high-cost products. Salmonella spp. L. monocytogenes were...
Polyamines are involved in several plant physiological processes. In Arabidopsis thaliana, five FAD-dependent polyamine oxidases (AtPAO1 to AtPAO5) contribute homeostasis. AtPAO5 catalyzes the back-conversion of thermospermine (T-Spm) spermidine and plays a role development, xylem differentiation, abiotic stress tolerance. present study, verify whether T-Spm metabolism can be exploited as new route improve tolerance crops investigate underlying mechanisms, tomato (Solanum lycopersicum)...
Abstract Herbaria are an important source of data and material useful in many fields, including plant conservation. Seeds preserved herbarium specimens may have the potential to germinate, although few studies focused on this topic. Here, first systematic assessment six techniques, priming techniques melatonin application, aimed at improving germination seeds from is presented. Seed 26 species common Europe, some which congeneric extinct species, collected herbaria wild (20,549 total, 19,509...
Copper-containing amine oxidases (CuAOs) catalyze polyamines (PAs) terminal oxidation producing ammonium, an aminoaldehyde and hydrogen peroxide (H2O2). Plant CuAOs are induced by stress-related hormones, methyl-jasmonate (MeJA), abscisic acid (ABA) salicylic (SA). In the Arabidopsis genome, eight genes encoding have been identified. Here, a comprehensive investigation of expression pattern four AtCuAOs from α γ phylogenetic subfamilies, two peroxisomal AtCuAOα2 (At1g31690) AtCuAOα3...
Plant copper amine oxidases (CuAOs) are involved in wound healing, defense against pathogens, methyl-jasmonate-induced protoxylem differentiation, and abscisic acid (ABA)-induced stomatal closure. In the present study, we investigated role of Arabidopsis thaliana CuAOδ (AtCuAOδ; At4g12290) ABA-mediated closure by genetic pharmacological approaches. Obtained data show that AtCuAOδ is up-regulated ABA two Atcuaoδ T-DNA insertional mutants less responsive to this hormone, showing reduced H2O2...
Polyamines (PAs) are ubiquitous low-molecular-weight aliphatic compounds present in all living organisms and essential for cell growth differentiation. The developmentally regulated stress-induced copper amine oxidases (CuAOs) oxidize PAs to aminoaldehydes producing hydrogen peroxide (H2O2) ammonia. Arabidopsis thaliana CuAOβ (AtCuAOβ) was previously reported be involved stomatal closure early root protoxylem differentiation induced by the wound-signal MeJA via apoplastic H2O2 production,...
The Arabidopsis gene AtCuAOβ (At4g14940) encodes an apoplastic copper amine oxidase (CuAO) highly expressed in guard cells of leaves and flowers root vascular tissues, especially protoxylem metaxylem precursors, where its expression is strongly induced by the wound signal methyl jasmonate (MeJA). hydrogen peroxide (H2O2) derived AtCuAOβ-driven oxidation substrate putrescine (Put), mediates MeJA-induced early differentiation. Considering that maturation was also both exogenous Put leaf...

Root architecture and xylem phenotypic plasticity influence crop productivity by affecting water nutrient uptake, especially under those environmental stress, which limit supply or imply excessive losses. Xylem maturation depends on coordinated events of cell wall lignification developmental programmed death (PCD), could both be triggered developmental- and/or stress-driven hydrogen peroxide (H₂O₂) production. Here, the effect wounding cotyledonary leaf root protoxylem was explored in...
Plant defence responses to adverse environmental conditions include different stress signalling, allowing plant acclimation and survival. Among these one of the most common, immediate, effective is modulation stomatal aperture, which integrates transduction pathways involving hydrogen peroxide (H2O2), calcium (Ca2+), nitric oxide (NO), phytohormones other signalling components. The Arabidopsis thaliana copper amine oxidases β (AtCuAOβ) encodes an apoplastic CuAO expressed in guard cells root...
Browning reactions caused by oxidative stress occurring during postharvest procedures significantly compromise the quality of ready‐to‐eat (RTE) vegetables, negatively affecting their market value. Polyphenol oxidase (PPO) and peroxidase (POD) are two major enzymes involved in this phenomenon, as they oxidize phenolic compounds to quinones, which turn polymerize brown pigments. Recently, there has been an increasing interest developing antibrowning treatments using food by‐products. Herein,...
The market of ready-to-eat salads is experiencing a noticeable growth in Europe. commercial success these products linked to the growing demand for fresh, healthy and nutritionally valuable that can be consumed without preparation time are perceived as safe very high-quality products.
