This study explores the molecular mechanisms underlying cold stress tolerance in the contrasting strawberry cultivars Queen Elisa (highly cold tolerant) and Camarosa (cold sensitive). Various physiological parameters were measured in these cultivars under cold stress and non‐stress conditions. RNA‐Seq was used to identify differentially expressed genes and enriched pathways involved in the plant response to cold stress. Biochemical data revealed that the cold‐tolerant cultivar under cold stress had higher levels of soluble carbohydrates and proline compared to the cold‐sensitive cultivar. Gene expression data demonstrated that cold‐tolerance and cold‐sensitive cultivars under cold stress modulated genes mainly involved in carbohydrate metabolism, hormone signaling, and secondary metabolism. GO and KEGG pathway enrichment data showed that cofactor biosynthesis, hormone signaling, and MAPK signaling were the most significantly enriched pathways in both cultivars. The transcription factors NAC , C2H2 , ERF , MYB , WRKY , bHLH , DREB , CONSTANS‐like , MADS , CCCH , and HY5, and several other key genes have been identified as closely associated with plant tolerance to cold stress. In particular, both contrasting cultivars respond similarly to cold stress, but the cold‐tolerant cultivar exhibited a broader modulation of stress‐related transcription factors and hormone signaling pathways, which were interpreted as a stronger molecular and biochemical response compared to the cold‐sensitive cultivar. Furthermore, several key genes are suggested to be associated with plant tolerance and are proposed as potential targets for the development of biotechnological tools based on transgenesis and genome editing in strawberries. Therefore, this research provides new insights into the genetic and molecular basis of strawberry tolerance to cold stress.

Sambucus is a cosmopolitan plant genus that has been used for centuries for its medicinal properties and nutritional value. Sambucus nigra, the most studied species, contains a wide range of bioactive compounds that have been linked to various health benefits. Moreover, the fruit of the elderberry is a rich source of phytochemicals and is used to make a variety of food products. In this review, after an introduction of the species, we outline the main points for its cultivation and production. We then illustrate the major phytochemical components and related beneficial properties, such as antioxidant, antimicrobial, and pharmaceutical activities. We also provide insights into genetic variability, functional diversity, and some evolutionary relationships that were evaluated with DNA-based techniques. We discuss that despite its long history of use and potential benefits, Sambucus nigra has received relatively little attention in terms of horticulture, breeding, and molecular genetics, while studies on its biochemical composition and health benefits are well developed. Further research is also needed to better understand the pre-harvest and post-harvest factors that influence plant growth and production, as well as to explore new applications and industrial uses of this underutilized species.

Rhus coriaria L., commonly known as sumac, is a shrub of the Anacardiaceae family present in various subtropical and temperate regions of the world. Considering the rich array of functional and nutraceutical ingredients, sumac extracts are an underutilized source of health-promoting dietary ingredients. For example, sumac is a spice with remarkable antioxidant activity thanks to the high presence of phenolic compounds. In addition, sumac extracts also possess antimicrobial activity and exhibit antidiabetic and hypoglycemic properties. Based on the scientific records retrieved in reliable citation databases (Scopus and Web of Science), this review comprehensively offers research results on sumac with a focus on the phytochemical profiles, the antimicrobial and antioxidant properties of the extracts, the pharmaceutical uses, and the genetic diversity. We discuss that the use of sumac as a climate-resilient tree should be promoted to diversify the food basket by leveraging on its multiple health benefits and also to reverse the abandonment of marginal lands under low irrigation.

Environmental degradation and the decrease of ecosystem service provision are currently of major concern, with current agricultural systems being a major driver. To meet our future environmental and sustainability targets a transformation of the agro-food systems and current agricultural value chain are crucial. One approach to redesign farming systems is the concept of biodiversity-based agriculture (BBA) which relies on sustainable diversification of biological components and their natural interactions in farming systems to maximize fertility, productivity, and resilience to external perturbations. Despite minimizing anthropogenic inputs, BBA is not yet able to meet all beneficial environmental objectives. BBA applied in the Mediterranean basin requires urgent innovation in approaches, methodologies, and models for small-holder traditional farming systems to ensure a stable provision of ecosystem services and better resilience to environmental stresses linked to climate change. Legumes are the backbone of the Mediterranean agro-ecosystems from ancient times, but their unique and wide biodiversity was not sufficiently valorized, especially by North-African countries. Here, we present LEGU-MED, a three-year international project funded by PRIMA initiative 2019. An international consortium was established involving five universities, 5 research institutes, and one private company from 8 countries: Italy, Germany, Spain, Algeria, Tunisia, Turkey, Lebanon, and Croatia. The main objective of this project is to put forward an international and well-integrated plan to valorize the legume agrobiodiversity of the Mediterranean in biodiversity-based farming systems and consequently enhance agro-ecosystem functions and services in the Mediterranean basin. The successful completion of LEGU-MED will have the following impacts on Mediterranean legume-based farming systems: (1) improve water use efficiency, (2) reduce the use of anthropogenic inputs through the maintenance of soil fertility, (3) enhance pollination and improve ecological connectivity with flora and fauna, (4) protect close-by wildland ecosystems, (5) enhance other ecosystem services (e.g., pest, disease, and weed suppression), and (6) provide healthier and safer protein-rich food.

Hawthorn (Crataegus monogyna Jacq.) is a wild edible fruit tree of the genus Crataegus, one of the most interesting genera of the Rosaceae family. This review is the first to consider, all together, the pharmaceutical, phytochemical, functional and therapeutic properties of C. monogyna based on numerous valuable secondary metabolites, including flavonoids, vitamin C, glycoside, anthocyanin, saponin, tannin and antioxidants. Previous reviews dealt with the properties of all species of the entire genera. We highlight the multi-therapeutic role that C. monogyna extracts could have in the treatment of different chronic and degenerative diseases, mainly focusing on flavonoids. In the first part of this comprehensive review, we describe the main botanical characteristics and summarize the studies which have been performed on the morphological and genetic characterization of the C. monogyna germplasm. In the second part, the key metabolites and their nutritional and pharmaceutical properties are described. This work could be an essential resource for promoting future therapeutic formulations based on this natural and potent bioactive plant extract.
