“…Shoot samples (0.25 g FW) were also extracted in 2 mL of 70% (v/v) methanol at 4 • C for 30 min of incubation; afterwards, the extracts were centrifuged for 20 min. The supernatant was used for the spectrophotometric determination of the concentration of total phenols and flavonoids as well as the total antioxidant capacity, as previously reported [13,16]. Total phenolic concentration was expressed as milligrams of gallic acid equivalents (GAE) per gram of FW, the total flavonoid content as milligrams of (+)-catechin equivalents (CE) per gram FW, and the total antioxidant capacity as µmol Trolox equivalent per gram FW (TEAC).…”

Among halophyte plants, Salicornia species (also known as glasswort or sea asparagus) are increasingly grown in open fields and greenhouses for edible or non-edible purposes. Their salinity tolerance makes it possible to irrigate Salicornia plants with saline waters and even seawater, which cannot be used by other crop species. In this work, S. europaea (L.) was cultivated in pots under the typical climatic conditions of the fall season in the Mediterranean region and irrigated with non-saline standard nutrient solution (SNS) or saline wastewater discharged from a greenhouse semi-closed hydroponic (substrate) culture of tomato or a saltwater recirculating aquaculture system (RAS) with Gilthead sea bream (Spaurus aurata L., which was used as such or after dilution (50:50) with SNS. Plant growth was not significantly affected by the composition of irrigation water, while higher antioxidant capacity (measured using the DPPH assay) and concentration of photosynthetic pigments, phenols, flavonoids, and ascorbic acid were found in the shoots of SNS plants than in those of plants irrigated with wastewater. The level of lipid peroxidation and H2O2 production significantly increased in the SNS plants, which also showed higher activity of superoxide dismutase and lower activity of catalase. These results suggest that S. europaea can be cultivated using wastewater with moderate to high salinity discharged from greenhouse hydroponic crops or RASs, and that salt is not strictly required for the growth of this species. Using non-saline nutrient solution can result in moderate oxidative stress that improves the shoot quality of S. europaea.

“…Chemical analyses allowed the characterization of primary and secondary metabolites that are typical of each of these plants with a focus on health, nutraceutical and bioactive functions [194,196,204,[207][208][209][210][211][212][213][214][215][216][217][218][219][220][221].…”

“…Edible flowers are often characterized by different flavors (sweet, bitter, sour and spicy) and have been characterized nutritionally [255]. They are rich in essential amino acids, minerals, polyunsaturated fatty acids and above all in substances with antioxidant, antimicrobial and anti-inflammatory properties (e.g., polyphenols and vitamins) [220]). These nutritional characteristics make edible flowers ideal for vegan and vegetarian diets.…”

Conservation, characterization and exploitation of agrobiodiversity are key factors to guarantee food security and face future challenges such as climate changes. These issues are the subject of a series of international agreements, such as the Convention of Biological Diversity, with its Nagoya Protocol, and the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) adopted in 2001 and entered into force in 2004. Italy ratified the Treaty in 2004 and instituted a long-lasting program, RGV-FAO, to implement it. CREA is one of the three organizations involved in the RGV-FAO Program, together with the National Research Council (CNR) and Reti Semi Rurali. CREA maintains a total of 40,186 accessions including cereals, vegetables, fruits, forages, industrial crops, forest and woody crops, medicinal and aromatic plants, and their wild relatives. Accessions are conserved using different ex situ conservation systems (seeds, in vivo plants, vegetative organs and in vitro plantlets), and characterized using genetic, morpho-phenological and/or biochemical methods. Herein, we will present the CREA long-lasting program RGV-FAO with some examples of the use of plant genetic resources in breeding programs, including molecular approaches. Some critical issues related to access and benefit sharing in PGRFA, such as the Nagoya Protocol and the Digital Sequence Information, will be discussed, highlighting their potential impact on food security and on the advancement of knowledge.
