Quinolizidine Alkaloid Composition of White Lupin Landraces and Breeding Lines, and Near-Infrared Spectroscopy-Based Discrimination of Low-Alkaloid Material Open
White lupin improvement is challenged by the need to select for low seed content of total quinolizidine alkaloids (QAs) when crossing low-alkaloid (sweet-seed) with bitter-seed (landrace) material. This study, which focused on 45 internati…
Marine microalgae extracts as plant biostimulant to boost baby leaf lettuce production Open
The application of biostimulants derived from microalgae may represent a promising strategy to enhance fruit and vegetable yields, particularly in the context of ongoing climate change. Yet, comprehensive studies assessing the efficacy of …
Identification of a new QTL associated to reduced quinolizidine alkaloid content in white lupin (Lupinus albus, L.) and development of ultra-low alkaloid recombinants by stacking with the pauper allele Open
The discovery of this novel locus and the development of associated PACE markers, potentially applicable for marker-assisted selection together with pauper (especially after farther validation in a larger panel of accessions), can enhance …
Effect of polyphenolic extracts from leaves of Mediterranean forage crops on enzymes involved in the oxidative stress, and useful for alternative cancer treatments Open
In this investigation, we report the ability of polyphenolic extracts from leaves of Lotus ornithopodioides, Hedysarum coronarium, Medicago sativa, and Cichorium intybus to affect the activity of key enzymes involved in the cellular redox …
Saponins in soil, their degradation and effect on soil enzymatic activities Open
Saponins can be potential candidates for the development of safe biopesticides, due to their widely acknowledged insecticidal, fungicidal and nematicidal activity, but information on their effects on soil biological properties is still lim…

The saponin bomb: a nucleolar‐localized β‐glucosidase hydrolyzes triterpene saponins in <i>Medicago truncatula</i> Open
Summary Plants often protect themselves from their own bioactive defense metabolites by storing them in less active forms. Consequently, plants also need systems allowing correct spatiotemporal reactivation of such metabolites, for instanc…
Nematicidal Potential of Sulla (Hedysarum coronarium L.) against the Root-Knot Nematode Meloidogyne incognita Open
The content of nematicidal metabolites such as saponins, flavonoids and tannins in sulla (Hedysarum coronarium L.) suggests its potential nematicidal activity. In this study, the biocidal activity of 62.5–1000 μg mL−1 concentrations of fla…
The Antioxidant Activity of a Commercial and a Fractionated Phycocyanin on Human Skin Cells In Vitro Open
The protective effects for cells against chemical and UVA stress of a commercial phycocyanin (PC) for food use and a PC extracted from Arthrospira platensis (Spirulina) in phosphate buffer were assessed. The purity of the commercial PC, sp…
In Search of Antifungals from the Plant World: The Potential of Saponins and Brassica Species against Verticillium dahliae Kleb. Open
Control methods alternative to synthetic pesticides are among the priorities for both organic and conventional farming systems. Plants are potential sources of compounds with antimicrobial properties. In this study, the antifungal potentia…
The saponin bomb: a nucleolar liquid-liquid phase-separated β-glucosidase hydrolyses triterpene saponins in Medicago truncatula Open
Plants often protect themselves from their own bioactive defense metabolites by storing them in less active forms. Consequently, plants also need systems allowing correct spatiotemporal reactivation of such metabolites, for instance under …
Rare fatty acids and lipids in plant oilseeds: occurrence and bioactivity Open
Lipids are biomolecules which are present in plants as general metabolites with different functions such as structural, protective and also as storage material. Plants produce a high number of different fatty acids: the most common structu…
Fruit and Vegetable Wholesale Market Waste: Safety and Nutritional Characterisation for Their Potential Re-Use in Livestock Nutrition Open
Compared to other food categories, fruits and vegetables are the most wasted. This leads to the squandering of economic, social, and environmental resources. The reallocation of fruit and vegetable waste (FVW) into animal feed contributes …
Chemical Identification of Specialized Metabolites from Sulla (Hedysarum coronarium L.) Collected in Southern Italy Open
Sulla (Hedysarum coronarium L.) is a biennal forage legume originated from the Mediterranean basin and used for animal feeding due to its high forage quality and palatability. Several species of Hedysarum have been considered for their nut…
