Abstract: BACKGROUND: Strawberry (Fragaria ×ananassa ) production is hampered by anthracnose caused by Colletotrichum spp. Cinnamyl alcohol dehydrogenase (CAD) catalyzes lignin biosynthesis to fortify plant cell wall upon various stresses, but their involvement in strawberry resistance is elusive. OBJECTIVE: Current work aims to uncover the involvement of CAD genes in both woodland and cultivated strawberry responses to Colletotrichum spp. METHODS: Genome-wide identification of CAD genes was updated in cultivated strawberry. Comparative molecular characterization integrated with pathogenesis phenotyping after C. fructicola inoculation, were followed by RT-qPCR analysis and RNAseq data retrieval. …RESULTS: Cultivated strawberry comprises 32 CAD genes of three classes. Thirteen syntenic relationships were observed between cultivated and woodland strawberry, with high homology in protein coding regions while promoters being greatly diversified. F. vesca ‘Hawaii4’ was least susceptible, followed by octoploid cultivar ‘ShenQi’, and ‘Benihoppe’ the most susceptible to C. fructicola . The class I CAD4 and CAD5 , preferentially expressed in leaves and crowns, respectively, were up-regulated in susceptible varieties at 72 h post inoculation (hpi). Of class II, CAD8 was up-regulated in three genotypes at distinct timepoints, while CAD12 was quickly down-regulated in ‘ShenQi’ upon inoculation. CAD1 and CAD2 of class III were down-regulated in ‘ShenQi’ and ‘Hawaii4’ at distinct stages. The strong involvement of CAD genes in strawberry response to Colletotrichum spp. sets a basis for future functional study. CONCLUSION: F. vesca is less susceptible to Colletotrichum spp. than cultivated strawberries but the expression of CAD family in F. vesca and F. ×ananassa were differentially provoked in timing and magnitude hinting no correlation with strawberry resistance to this pathogen.

Abstract: BACKGROUND: Cranberries, black and red currants, strawberries, chokeberries, raspberries, blueberries and blackberries, due to the high content of polyphenolic compounds, become an excellent matrix for the production of preparations that can be used as nutraceuticals. OBJECTIVE: Evaluation of the content of bioactive compounds and health-promoting activity of preparations from polyphenolic fractions isolated from eight types of berries. METHODS: The preparations were obtained by lyophilization of the polyphenolic fraction of fruit extracts, and then they were evaluated in terms of physicochemical properties, content of polyphenolic compounds and antioxidant, antidiabetic, antiobesity and anticancer activity. RESULTS: The …analyzes showed a very diverse content of bioactive compounds and a high health-promoting potential significantly depending on the type of fruit. In total, 61 polyphenolic compounds were identified, with anthocyanins being the dominant group. A positive correlation was found between the content of polyphenolic compounds and high antioxidant activity. A cytotoxic effect on colorectal adenocarcinoma cells (Caco-2) was also found. In addition, all the obtained preparations turned out to be effective inhibitors of enzymes promoting diabetes and obesity. CONCLUSIONS: The obtained preparations can be used in the production of nutraceuticals or functional food additives, applicable in the prevention and treatment of lifestyle diseases. Show more

Abstract: BACKGROUND: Grapes, which have gained prominence in recent years due to their positive contributions to human health, are considered a functional food due to the oil content in their seeds. Although the oil content and fatty acid composition of commonly grown grape varieties have been the subject of many studies, these characteristics of local varieties haven’t been sufficiently examined. OBJECTIVE: This study was carried out to determine the usability of grape varieties grown in Southeastern Anatolia (Turkey) in grape seed oil production and identify potential parent candidates that could be used in the breeding of grape varieties with …high-quality seed oil. METHODS: The effects of genotypes, berry skin color, ripening time, and the climatic characteristics of the cultivation season on the oil content and fatty acid composition of seeds from 16 different grape (Vitis vinifera L.) varieties were investigated. Grape seed oils were extracted by soxhlet device and major, minor, and essential fatty acid compositions were determined by gas chromatography. RESULTS: According to the findings, the oil content of the grape seeds varied only depending on the genotype and ranged from 9.78% to 18.50% w/w. Moreover, 13–15 fatty acids were detected in the grape seed oils, with linoleic acid (56.13% –69.36%) and oleic acid (15.99% –30.97%) being the most common in all varieties. Only palmitic acid and stearic acid showed variation depending on the skin color; the other fatty acids weren’t affected. Cultivation season didn’t affect the fatty acid composition, but the major and minor fatty acid composition varied depending on ripening time. CONCLUSIONS: In cases where it isn’t possible to separate the seeds of grape varieties on a variety basis, classifying them according to the ripening time of the berries may be helpful in predicting the amounts of major, minor fatty acids and partially essential fatty acids in the seeds.

Abstract: Barberries are versatile shrubs with diverse applications, including ornamental, medicinal, and edible purposes. In this study, we employed molecular markers to assess the genetic diversity and genetic base of superior barberry genotypes selected from an F1 population obtained through Shahrood University Barberry Breeding Program (SUBBP), alongside their parents. We utilized nine ISSR markers and 10 RAPD markers to analyze the population’s genetic diversity. From these markers, we obtained 98 polymorphic bands using ISSR markers and 112 polymorphic bands using RAPD markers. The average PIC value was 0.16 for ISSR markers and RAPD markers, while the average genetic resolution power was …3.93 for ISSR markers and 2.11 for RAPD markers. Furthermore, we calculated the genetic dissimilarity coefficient (GDC) based on ISSR and RAPD markers, which ranged from 0.23 to 0.86 (average 0.62) and 0.21 to 0.85 (average 0.60), respectively. The ISSR data analysis classified the genotypes into three main clusters, with genotypes 0515 , R5N1 , ‘Bth’, ‘Seedless (BD)’, and R2N1 being genetically distant from the others. Similarly, the analysis of 10 RAPD primers resulted in the classification of genotypes into three main groups. Notably, genotype 0609 exhibited greater genetic distance from other genotypes in this subgroup. The Principal Coordinates Analysis (PCoA) using both ISSR and RAPD marker data further supported the grouping of genotypes into three distinct clusters. These results provide valuable insights into the genetic composition of the F1 population and contribute to the advancement of barberry breeding strategies. Show more

Abstract: BACKGROUND: Mulberry (Morus ) from the Moraceae family is distributed widely in tropical to temperate regions of the world having economic and medicinal significance with exceptional nutritional characteristics. OBJECTIVES: Assessment of variations in sugars, acidity, minerals, total phenolics, anthocyanins and antioxidant potentials of three black mulberry (Morrus serrata, M. nigra and M. macroura black) and two white mulberry cultivars (M. alba and M. macroura white) during development stages. METHODS: Total sugars and acidity were evaluated with AOAC methods and total phenolic content was estimated with folin-ciocalteau method. Antioxidant activity was evaluated with …DPPH assay, minerals were quantified with atomic absorption spectroscopy and anthocyanins were assessed and identified with high performance liquid chromatography and liquid chromatography-mass spectroscopy. RESULTS: Over all, M. alba (white cultivar) displayed maximum sugar (1.35%) at fruit development stage 3 (FDS-3) following M. serrata (black cultivar) at FDS-5 (1.1%) and M. macroura white (white cultivar) at FDS-4 (0.9%). Acidity decreased in M. alba (0.8–0.09%), M. nigra (0.8–0.03%) and M. macroura white (0.6–0.04%) during development. Total phenolic content was maximum (590 GAE/100 g) in M. nigra at FDS-6 and M. serrata (450 GAE/100 g) at FDS-7. Two black cultivars (M. serrata and M. nigra ) showed significant increase in total anthocyanins (14.57–100.06 and 14.13–201.87 CGE/100 g FW) from FDS-1 to FDS-7 while decrease in M. macroura black and M. macroura white (17.07–11.79 and 9.03–2.68) from FDS-1 to FDS-7. The DPPH inhibition of black mulberries was pointedly greater with significant levels of iron, copper, zinc, calcium, magnesium, sodium, phosphorus and potassium than white cultivars during maturity. HPLC and LC-MS procedures identified various anthocyanins in all cultivars including cyanidin, malvidin, pelargonidin and delphinidin. CONCLUSIONS: Mulberries with improved nutrition, acceptable range of metals, bioactive compounds and higher antioxidant potentials could be significant against various diseases like cancer, cardiovascular problems, neurodegenerative disorders, obesity, diabetes and other metabolic syndromes.
