OBJECTIVE: To characterize the Andean berry aqueous extract and to study their anti-proliferative mechanisms on SW480 and SW620 cell lines (human colon adenocarcinoma). METHODS: Total phenolic and total anthocyanins contents were determined by Folin-Ciocalteau and differential pH methods, respectively. Antioxidant activity was measured by FRAP, ORAC and DPPH methods. Antiproliferative effect was determined by sulforhodamine colorimetric method and apoptosis was analyzed by flow cytometry using propidium iodide/Annexin-V. Mitochondrial potential was evaluated using DIOC6 and ROS levels were measured by 2,7-Dicholorodihydrofluorescein diacetate (DCFH-DA). RESULTS: The total phenol and anthocyanin content were 4409.78± 63,05 mg equivalents of gallic acid/100 mL and 106,57± 1.43 mg equivalents of cyanidin-3-glycoside/100 mL, respectively. Andean berry extract showed antioxidant activity by FRAP, ORAC and DPPH methods and antiproliferative effect on SW480 and SW620 cells. It was observed a cell cycle arrest at S and G2/M phases on SW480 and at G0/G1 phase on SW620 cells. Aqueous extract did not induce mitochondrial depolarization or affect intracellular ROS levels. CONCLUSIONS: Andean berry aqueous extract has antioxidant capacity and induces apoptosis involving cell cycle arrest in SW480 and SW620 cells without mitochondrial damage.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/JBR-200684","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48283971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While aw values of all grapes were decreased during drying, total soluble solids content increased. The values of pH and total acidity in grape samples significantly increased during the drying period due to the increase in dry matter content. The results showed that all the drying treatments significantly increased the total phenolic content, total antioxidant activity, trans-resveratrol, organic acid and sugar compounds. Trans-resveratrol amounts were slightly higher in the samples dried in the shade and in the dipping solution treatment and decreased as the drying time increases. An increase in organic acid and sugar contents was observed depending on the drying time. The change of colour was comparatively faster in dried samples with dipping solution. It was found that dipping solution treatment (7 days) reduced the drying time by half when compared to the samples without dipping solution treatment (15 days). This result is important for the grape producers of Karaman/Turkey, where the drying period under sun generally take 15 days.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/JBR-210703","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43420765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBJECTIVE: To elucidate the molecular differences of genes and pathways in the presence and absence of anthocyanins. METHODS: RNA sequencing (RNAseq) of red-fleshed strawberry ‘Benihoppe’ and its white-fleshed mutant ‘Xiaobai’ was performed. RESULTS: A total of 1,156 and 1,378 transcripts were differentially expressed (DE) in two cultivars at white stage and red stage respectively. Among them, 28, 49 and 72 DE transcripts were involved in AsA, sugars metabolism and plant hormones signaling respectively. Fruits of ‘Benihoppe’ with higher anthocyanins content contained higher AsA, the expression of D-galacturonate reductase (GalUR) in white-fleshed strawberry was down-regulated. Particularly, the expression of transcripts involved in sugars, jasmonic acid (JA) and abscisic acid (ABA) signaling was decreased, by contrast, the expression of transcripts involved in auxin and gibberellins (GAs) signaling was significantly increased. CONCLUSIONS: The lower AsA level in white-fleshed strawberry is possibly because of the lower flux of D-galacturonate biosynthesis pathway. Anthocyanins was associated with gene expression involved in AsA, sugars, and hormones signaling metabolisms.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"1 1","pages":"1-16"},"PeriodicalIF":1.7,"publicationDate":"2021-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/JBR-200685","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43626300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particular attention was devoted to Vaccinium L. berries, because of being commonly consumed in daily life and providing a large potential for the development of new pharmaceutical applications. OBJECTIVE: The present work aimed at establishing a novel UPLC-PDA method for profiling anthocyanins in berries and evaluating their distribution in cultivated lingonberries. METHODS: The method was developed and validated using bilberries (Vaccinium myrtillus L.), cranberries (Vaccinium macrocarpon Ait.), and lingonberries (Vaccinium vitis-idaea L.) matrices. Anthocyanins content variation was analyzed among 7 different cultivars and 1 infraspecific taxon of lingonberries. RESULTS: The proposed method ensured the separation of 20 compounds, including major and minor anthocyanins and their aglycones, in bilberries, 15 in cranberries, and 9 in lingonberries, during 12 min analysis. Bilberry matrix was distinguished by the most complex profile and the presence of delphinidin and petunidin, which were not identified either in cranberries or lingonberries. Cranberry anthocyanins consisted mainly of the 3-galactosides of cyanidin and peonidin, whereas lingonberry anthocyanins included cyanidin and its glycosides with just traces of other anthocyanins. Obtained anthocyanins fingerprinting results have guidance function in practice and demonstrate valuable chemophenetic information for studied Vaccinium berries. All determined method validation values were considered to be acceptable. Variation analysis of anthocyanins levels among cultivated lingonberries suggested genetic diversity and because of the highest anthocyanins content—the superiority of Russian cultivars (‘Kostromička’ and ‘Rubin’). To the best of our knowledge, this is the first comprehensive report on the anthocyanins of certain lingonberry cultivars. CONCLUSIONS: This study resulted in the rapid, simple, and validated method, which was shown to be applicable and convenient for routine analysis and authentication of Vaccinium berry samples.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"1 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/jbr-200658","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70018064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MADS-box genes play an important role in the regulation of fruit development in angiosperms. OBJECTIVE: To understand the regulatory role of the MADS-box family, a total of 80 MADS-box genes were identified and analyzed. METHODS: The MADS-box genes in the black raspberry genome were analyzed using bioinformatics methods. Through an analysis of the promoter elements, the possible functions of different members of the family were predicted. The spatiotemporal expression patterns of members of the MADS-box family during black raspberry fruit development and ripening were systematically analyzed. RESULTS: The genes were classified into type I (Mα: 33; Mβ: 6; Mγ: 10) and type II (MIKC*: 2; MIKCC: 29) genes. We also obtained a complete overview of the RoMADS-box gene family through phylogenetic, gene structure, conserved motif, and cis element analyses. The relative expression analysis showed different expression patterns, and most RoMADS-box genes were more highly expressed in fruit than in other tissues of black raspberry. CONCLUSIONS: This finding indicates that the MADS-box gene family is involved in the regulation of fruit ripening processes in black raspberry.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"1 1","pages":"1-15"},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/JBR-200679","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70017765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, textural parameters were evaluated. METHODS: It was determined the changes in some selected physical properties, such as: moisture, total solid contents, one-dimensional shrinkage and texture, at 30 min steps during OD treatment. Besides, water and solid diffusion coefficients ( D e W and D e TS , respectively) were calculated by using the analytical solution of Fick’s equation. RESULTS: Diffusion coefficients for water and solids showed significant differences due to coating presence as an evidence of the barrier effect. Coated strawberry samples presented several changes after 2 h of OD treatment at the assayed conditions for most of the parameters evaluated. CONCLUSIONS: Alginate coating at the tested conditions acts as a barrier to sucrose influx and to water outflux until 2 and 3 h of OD treatment, respectively.

To date, information about the involvement of HD-Zip in grape to drought response is limited. OBJECTIVE: The production of grapes is limited by a range of biotic and abiotic stresses, which cause significant losses in yield every year as well as a reduction in fruit quality. Identification and analysis of stress related genes in grapes are very important for cultivating more robust varieties with environmental stress resistance METHODS: We isolated a homeodomain-leucine zipper gene (HD-Zip), VvHDZ4, from grape, Vitis vinifera L. “Yatomi Rose”, and characterized VvHDZ4 based on analyses of its expression patterns, subcellular localization, transcription activity, and overexpression. RESULTS: We found that VvHDZ4 was highly expressed in roots and leaves, localized to nucleus, and activated the expression of reporter genes in yeast. The overexpression (OE) of VvHDZ4 led to enhanced drought stress tolerance in Solanum lycopersicum L. “Ailsa Craig” (tomato). The drought-tolerant phenotypes of the OE lines exhibited decreases in electrolyte leakage and rate of water loss, higher photosynthetic production and net photosynthesis rate, and showed up-regulation of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX), all of which are key antioxidant enzymes known to be activated during drought stress. Moreover, we observed the up-regulation of four additional drought stress indicator genes, SIDREB2A, SIAREB, SIRD29 and SIERD10, in the OE lines. VvHDZ4 improved drought tolerance in tomato, and the modes of action possibly consist of reducing membrane damage, increasing photosynthetic productivity, and modulating the expression of stress defense genes. CONCLUSIONS: This work increases our understanding of the important roles HD-Zip transcription factors in the responses of plants to the environment, especially abiotic stress.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"1 1","pages":"1-13"},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/JBR-200632","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70017259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, intersectional hybrids between Japanese wild species Shashanbo and highbush blueberry were produced using polyploid breeding for the first time. However, the polyphenol contents, antioxidant activities, and anti-cancer cell proliferation properties of the fruits of these intersectional hybrids have not been studied sufficiently. OBJECTIVE: The objectives of this study were to determine the anthocyanin contents, polyphenol contents, and antioxidant activities at each stage of fruit development in intersectional hybrids, and to examine the effects of the fruit extracts on anti-cancer cell proliferation properties using human promyelocytic leukemia (HL-60) cells. METHODS: Freeze-dried fruit samples of three intersectional hybrids and their parents at five developmental stages were used to evaluate their polyphenol contents, anthocyanin contents, and levels of two types of antioxidant activities (DPPH and ORAC). The anti-cancer cell proliferation properties of each extract were also evaluated according to the survival rate of HL-60 cells. RESULTS: The total polyphenol contents in fruits of the intersectional hybrids gradually decreased as the fruits grew, but the contents increased slightly at the mature stage. Meanwhile, the total anthocyanin contents increased strongly to the mature stage. In addition, the fruit extract of intersectional hybrid JM1 was found to be more effective for inhibiting the growth of HL-60 human leukemia cells in vitro. Total polyphenol content correlated highly with antioxidant activities and anti-cancer cell proliferation properties. CONCLUSIONS: We clarified that the intersectional hybrids had produced have abundant bioactive compounds, high levels of antioxidant activities, and anti-cancer cell proliferation properties.
