In vitro plant regeneration of caper (Capparis spinosa L.) from floral explants and genetic stability of regenerants

2011

A new technique to regenerate caper plants (Capparis spinosa L. subsp. rupestris) starting from flower explant is reported. In vitro plant regeneration was attempted using stigma, anthers and unfertilized ovules of unopened flowers collected in the field. Plant regeneration was achieved from unfertilized ovules on MS medium supplemented with 88 mM sucrose and 13 lM 6-benzyladenine (BA). New individuals obtained from unfertilized ovules were used as source material for micropropagation and multiple shoots were obtained on MS medium sup- plemented with the adeninic cytokinin BA and the auxin indole-3-butyric acid (IBA). Explants obtained in micro- propagation step were used for rooting step u…

From extraction of valuable compounds to health promoting benefits of olive leaves through bioaccessibility, bioavailability and impact on gut microb…

2019

Abstract Background The beneficial effects of olive leaves are known from ancient times. In this regard, both the olive leaves and the different preparations obtained from them (e.g. infusions, extracts) have been traditionally used for the treatment of various diseases or to alleviate the symptoms associated with different pathologies. In addition, the use of olive leaves extracts as nutraceuticals along today's continuous usage in cosmetics and medicine is common. Scope and approach Most of the health-related benefits of olive leaves have been associated to their high content in antioxidant bioactive compounds such as polyphenols, carotenoids, etc., being oleuropein and hydroxytyrosol som…

A266 AMYLASE TRYPSIN INHIBITORS FROM WHEAT EXACERBATE GLUTEN-INDUCED PATHOLOGY AND ALTER GUT MICROBIOTA IN MICE

2018

BACKGROUND: Celiac disease (CeD) is an autoimmune enteropathy triggered by gluten in genetically susceptible individuals expressing HLA DQ2 or DQ8. The adaptive immune response is characterized by a gluten-specific T-cells, anti-gluten and anti-tissue transglutaminase-2 antibodies. Proliferation and activation of intraepithelial lymphocytes (IELs) is central to the innate immune response, although the triggers and receptors remain unclear. Amylase trypsin inhibitors (ATIs) are pest-resistant molecules in modern wheat with TLR4-activating capacities in mononuclear phagocytic cells. AIMS: Our aim was to determine whether ATIs act as innate activators, enhancing gluten immunopathology in mice.…

Omega-3 PUFAs and gut microbiota: A preventive approach for colorectal cancer

2021

The influence of diet on the composition of the intestinal microbiota and related pathologies has been known for some time. Some classes of nutrients, such as fatty acids belonging to the omega 3 series, have particular effects on the bacteria that make up the intestinal microbiota. ω-3 PUFAs affect the gut microbiota in three different ways: by modulating the type and abundance of intestinal bacteria, by regulate SCFAs levels, and by alter the levels of proinflammatory mediators. Through these modalities, ω-3 PUFAs could be useful for the prevention of intestinal diseases such as Colorectal Cancer (CRC). The ability of ω-3 PUFAs to modulate the intestinal inflammatory response, to preserve…

The RIBES strategy for ex situ conservation: conventional and modern techniques for seed conservation

2022

The Italian seed bank network (RIBES) aims to improve the quality and safety of the germplasm reserves of native plant species in Italy to ensure the long-term conservation of endangered and/or endemic flora. The strategy includes traditional methods to secure seed conservation. A comprehensive priority list for seed collection is being defined, it was prepared by crossing data of various checklists (red lists, endemics) and will soon be cross-referenced with an updated list of accessions of the whole network. A safety-backup program of duplicates will quickly be implemented to secure the conservation of the most threatened species in at least two seed banks of the network. On the other han…
