Strawberry tree (Arbutus unedo L.) is a species that generally grows in the Mediterranean region and coasts and has been consumed as food since ancient times. Its fruits are mostly used in alcoholic beverages and various jams and desserts. Its fruits and leaves contain different phenolic compounds, because of this it is used in traditional folk medicine. They have different biological properties like, anti-diabetic, anti-inflammatory, urinary antiseptic, antihypertension, astringent, anti-diarrheal due to their high quantity of tannins. In this study, we aimed that to determine the total antioxidant capacity of fruits and leaves and trace element contents of Arbutus unedo L. which were collected in Yalova (TURKEY). The antioxidant activities of samples were examined by ferric reducing/antioxidant power (FRAP) method, cupric reducing antioxidant capacity (CUPRAC) method and trolox equivalent antioxidant capacity (TEAC) assay with ABTS radical cation. In the samples of the amount of total phenolic and tannins contents were determined using the Folin-Ciocalteu reagent (FCR) method. In adddition to, we determined the concentrations of Al, Cd, Cu, Cr, Fe, Mn, Pb, Zn in the samples by using ICP-MS. As a result, Arbutus unedo L. is a good source of antioxidants and minerals, it was stated that single antioxidant activity test would present limited information about the power of the antioxidant capacity and it was emphasized that use of combination of various methods should be used in assessing the antioxidant activities in vitro. It has been determined that the trace elements are within the determined limits.

“…Since wheatgrass can be easily grown in home cultivation, the aim of this study was to determine the influence of genotypes and cuttings on the content of metabolites with the antioxidant properties in wheatgrass juice. Savsatli (2020) suggested that it is important to determine the appropriate cultivars M. Kristić et al: THE INFLUENCE OF VARIETY AND CUTTING ON THE WHEATGRASS ... for the industry. Moreover, the wild wheat relatives are rarely investigated in terms of their genetic potential for a secondary metabolite synthesis.…”

Due to its nutritional value, wheatgrass (Triticum aestivum L.) is considered to be a functional food, becoming increasingly popular as a supplement to the people’s quotidian diet. The study aimed to determine the influence of the number of cuttings and cultivars on the total antioxidant activity (DPPH), the content of chloroplast pigments, vitamin C, phenols, and flavonoids in the wheatgrass juice. Two genotypes of wheatgrass, T. aestivum ssp. aestivum (variety Katarina) and T. aestivum ssp. sphaerococcum, respectively, were cut twice during the experiment. In both cuttings, the genotype significantly differed in the flavonoid level and antioxidant activity, while the number of cuttings influenced the content of phenols, vitamin C, and antioxidant activity in the wheatgrass juice. T. sphaerococcum had a higher concentration of flavonoids and a significantly lower antioxidant activity when compared to the Katarina wheat variety. On an average, the first cut implicated an increased content of phenols and vitamin C concerning both genotypes, followed by a higher antioxidant value. In the Katarina variety, a significantly higher phenol content and antioxidant activity was detected in the first cut. In the T. Sphaerococcum, a decrease in the total content of the examined antioxidants was apparent in the second cut.

GDSL-type esterase/lipase proteins (GELPs) characterized by a conserved GDSL motif at their N-terminus belong to the lipid hydrolysis enzyme superfamily. In plants, GELPs play an important role in plant growth, development and stress response. The studies of the identification and characterization of the GELP gene family in Triticeae have not been reported. In this study, 193 DvGELPs were identified in Dasypyrum villosum and classified into 11 groups (clade A–K) by means of phylogenetic analysis. Most DvGELPs contain only one GDSL domain, only four DvGELPs contain other domains besides the GDSL domain. Gene structure analysis indicated 35.2% DvGELP genes have four introns and five exons. In the promoter regions of the identified DvGELPs, we detected 4502 putative cis-elements, which were associated with plant hormones, plant growth, environmental stress and light responsiveness. Expression profiling revealed 36, 44 and 17 DvGELPs were highly expressed in the spike, the root and the grain, respectively. Further investigation of a root-specific expressing GELP, DvGELP53, indicated it was induced by a variety of biotic and abiotic stresses. The knockdown of DvGELP53 inhibited long-distance movement of BSMV in the tissue of D. villosum. This research provides a genome-wide glimpse of the D. villosum GELP genes and hints at the participation of DvGELP53 in the interaction between virus and plants.
