BACKGROUND:Besides providing nutritional value, functional foods have potential beneficial effects on health. Consumers worldwide seek food products with added value based on physical and mental well-being. OBJECTIVE:This study aimed to analyze the urinary metabolome of volunteers who consumed a drink based on Costa Rican blackberries (Rubus adenotrichos) to identify the presence of urolithins and other possible bioactive compounds related to beneficial effects on health. METHODS:Fifteen healthy non-smoking male volunteers aged between 19 and 43 years old who consumed 250 ml of blackberry-based drink for breakfast for eight consecutive days were selected. Urine samples were obtained before and after drink consumption, which were submitted to analysis by Ultra-Performance Liquid Chromatography coupled to a Mass Detector (UPLC/ESI-Q-TOF-MS). Subsequently, a metabolomic analysis of the results was performed to identify the presence or absence of urolithins and other bioactive metabolites related to blackberry juice consumption. RESULTS:It was possible to detect high intensity presence of urolithin A (n = 6) and high intensity presence of both urolithin A and B (n = 5) in urine samples in several volunteers. However, finding them was impossible in others, or they were at very low intensities (n = 4). Likewise, it was possible to identify Menth-1-en-4,8 diol glucuronide and 1-O-E-Cinnamoyl-(6-arabinosylglucose) as other compounds related to the consumption of blackberries. CONCLUSIONS:The consumption of Costa Rican blackberries allowed us to demonstrate the presence of three metabotypes within the study population: 40% of strong urolithin A (UAP) producers, 33.3% of both urolithin (A and B) producers (UBP), and 26.7% of weak urolithin A producers (0P). Finally, it is recommended to carry out more research in this regard, considering a greater number of volunteers and including people of both sexes.

BACKGROUND:Postharvest decay caused by Botrytis cinerea (gray mold) and Fusarium solani (fruit decay) negatively affects strawberry fruits during handling and marketing. OBJECTIVE:The effect of cinnamon oil, sodium benzoate, potassium sorbate and/or pomegranate peel powder were estimated on the growth of the two pathogenic fungi and their fruit decay incidence under in vitro and in vivo conditions. METHODS:The isolated fungi from decayed strawberry fruits were identified as Botrytis cinerea and Fusarium sp. The isolated Fusarium sp. was identified molecularly as Fusarium solani and registered in GenBank under accession number ON248575.1 (https://www.ncbi.nlm.nih.gov/nuccore/ON248575.1). RESULTS:Complete fungal growth suppression was observed at a concentration of 3% for all tested materials, Additionally the same (100%) effect was achieved at 2% of a combination of essential oil, salts and pomegranate peel powder. Significant reduction in decay incidence and severity was observed in inoculated strawberry fruits treated with the same concentrations of the tested materials after 10 and 15 days of storage. CONCLUSIONS:The results demonstrate that cinnamon oil, sodium benzoate, potassium sorbate and/or pomegranate peel powder have potency as eco-friendly products, for safe postharvest treatments against strawberry fruit rots during storage. They could be recommended for use in packing-houses due to their wide utilization as safe food preservatives.

BACKGROUND:The fig (Ficus carica L.) tree known for its tasty and nutritious fruits, is typically propagated by cutting. While previous studies have focused on the effects of different treatments and environmental conditions on fig cutting propagation, little attention has been paid to the specificrole and association of biochemical properties in leaves, stem bark and fruit on the rooting process. OBJECTIVE:This research explores the complex relationship between 40 biochemical traits and the rooting ability of fig cuttings. To achieve this objective, various machine learning techniques were employed, such as a random forest model, feature importance analysis, linear regression, and principal component analysis (PCA). RESULTS:The random forest model showed significant predictive ability with a classification accuracy of 100%, supported by a high kappa statistic. Feature importance analysis identified a* (a colorimetric parameter in fruit), fruit trans-ferulic acid and leaf total flavonoids as the most influential traits in determining the rooting ability of cuttings. The robustness of these findings is supported by the high R-squared value (0.9002) and low error metrics (MAE 0.7554 and MSE 0.6980) of the linear regression model built on these important traits. In parallel, PCA indicated that a*, leaf total flavonoids and fruit trans-ferulic acid were the dominant traits in samples with lower rooting percentage. CONCLUSIONS:These identified biomarkers can be effectively used by fig breeders and growers to select and introduce fig cultivars with improved rooting ability.

BACKGROUND:Strawberry (Fragaria×ananassa Duch.) is a species of great economic and nutritional importance. It is widely cultivated in different regions of the world. However, climatic factors have a significant influence on its production. OBJECTIVE:To evaluate the ecoclimatic suitability and growth index of F.×ananassa in the face of the impacts of climate change in Brazil and the world. METHODS:The potential global distribution of F.×ananassa it was based on predicted global climate changes using CLIMEX and the A1B and A2 emissions scenario for the years 2050 and 2100. CLIMEX weekly growth index (GIw) was applied, and productivity data in commercial strawberry cultivation in Brazilian areas were collected. RESULTS:The results indicate a progressive reduction in areas suitable for strawberry cultivation globally, mainly on the African continent, Australia, China, and the Americas for the years 2050 and 2100. In Brazil, only the South region and part of the Southeast will continue to be suitable for strawberry production. CONCLUSIONS:The CLIMEX model predicts a reduction in the suitable area for cultivating Fragaria×ananassa Duch between 2050 and 2100 due to climate change. The generated maps can help identify new cultivation areas and support genetic improvement programmes to develop cultivars more tolerant to heat.

BACKGROUND:One of the biggest challenges facing the soft fruit sector is to propagate disease free strawberry plants in a timely manner, financially viable approach and in an eco-friendly fashion. OBJECTIVE:This study sets out to investigate the efficacy of growing everbearing Fragaria×ananassa ‘Malling Ace’ runners at different propagation dates and under Different LED lighting regimes using vertical farming units and glasshouse (as control). METHODS:To evaluate the effects of the treatment factors, some of the main horticultural features including rooting success rate, rooting speed, root and shoot biomass production, chlorophyll content and bud emergence were measured and statistically analysed. In addition, this study aimed to investigate the energy efficiency of a self-sufficient Direct Current (DC) based vertical farming unit, versus a vertical farming unit using the Alternate Current (AC) electricity provided by national grid electricity. RESULTS:light, tipping date, and the interaction between light and tipping date, significantly influenced shoot biomass, total crown diameter, and chlorophyll content in the leaves of ‘Malling Ace’. In terms of energy demand, the DC unit had a higher level of energy efficiency over AC unit with 23% less energy demand. CONCLUSION:In general, this trial demonstrated vertical farming as a potentially sustainable method and efficient tool in propagating strawberry plants.

BACKGROUND: The evaluation of chlorophyll fluorescence activity is a useful tool for rapid and effective assessments of the effect of abiotic factors on the physiology of different crops. In Rubus, this type of measurements describes tolerance to high temperatures, sensitivity to heat and morphological alterations in flowering and chlorophyll content, as a result of plant stress. OBJECTIVE: The present research estimated chlorophyll fluorescence and the presence of some phenolic compounds in the leaves of three cultivars of blackberry (Rubus sp.) established in the central region of Colombia, under conditions of open air between 2400 and 2800 masl. MATERIAL AND METHODS: This was done through the measurement of chlorophyll a (Junior-PAM II modulated fluorometer), the quantification of phenolic compounds (Folin Ciocalteu), the determination of antioxidant capacity (DPPH and ABTS) and the study of phenolic profiles (UHPLC) in leaves of three blackberry cultivars. RESULTS: Cultivars R. alutaceus (0.66), R. glaucus (0.73) and R. alpinus (0.76), presented values lower than the optimum (0.83), for the parameter F v /F m . In addition, the direct relationships between the parameters that define the behavior of PSII and the accumulation of different polyphenols were described. Reference was also made to the content of phenolic compounds (ranging from 125 to 150 mg GA g–1 dw), which did not show significant statistical differences. The heat map and principal component analysis show the close relationship between the parameters that characterize the functioning of PSII and the accumulation of phenolic compounds, as a mechanism of adaptation to the adverse conditions of the blackberry cultivars studied. CONCLUSIONS: The results reveal that the leaves of the Rubus studied could be a source of functional ingredients for use in the cosmetic, nutraceutical and food industries and epigallocatechin was attributed the greatest responsibility for the antioxidant capacity.
背景：叶绿素荧光活性评估是一种有用的工具，可用于快速有效地评估非生物因素对不同作物生理机能的影响。在鲁冰花（Rubus）中，这种测量方法描述了对高温的耐受性、对热的敏感性以及植物胁迫导致的开花和叶绿素含量的形态变化。目的：本研究估测了哥伦比亚中部地区三个黑莓（Rubus sp.）栽培品种在 2400 至 2800 米高的露天条件下叶片的叶绿素荧光和一些酚类化合物的含量。材料与方法：通过测量叶绿素 a（Junior-PAM II 调制荧光计）、酚类化合物定量（Folin Ciocalteu）、抗氧化能力测定（DPPH 和 ABTS）和酚类概况研究（超高效液相色谱法）来测定三种黑莓栽培品种叶片中的酚类化合物。结果：R. alutaceus（0.66）、R. glaucus（0.73）和 R. alpinus（0.76）的参数 F v/F m 值低于最佳值（0.83）。还参考了酚类化合物的含量（125 至 150 毫克 GA g-1 干重），其统计差异并不显著。热图和主成分分析表明，表征 PSII 功能的参数与酚类化合物的积累之间关系密切，这是黑莓栽培品种适应不利条件的一种机制。结论：研究结果表明，所研究的茜草叶可作为化妆品、营养保健品和食品行业使用的功能性成分的来源，表没食子儿茶素在抗氧化能力方面负有最大责任。

BACKGROUND: Polyphenolic-rich chokeberry extracts and juice could provide health benefits in humans. Moreover, by-products after processing stand out as a potential new source of valuable compounds. OBJECTIVE: The research aimed to evaluate in vitro bioactivity of chokeberry fruit extract, juice, and waste extract (material remaining after juice processing) based on their chemical composition and molecular docking analysis. METHODS: Spectrophotometric methods were used to determine the phenolics, anthocyanins, flavonoids, and proanthocyanins content in freeze-dried samples. Additionally, individual anthocyanins, flavonoids, and sugars were identified through HPLC analysis. The antioxidant capacity was tested using two in vitro methods and assessing antimicrobial activity. The effects of tyrosinase and acetylcholinesterase inhibition were examined using spectrophotometric methods. Molecular docking analysis identified the interaction of chokeberry components with the active sites of these enzymes. RESULTS: The waste extract exhibited the most robust antioxidant activity within the DPPH system. While bactericidal activity was absent across all chokeberry preparations, they demonstrated inhibitory effects on specific microbiological strains relevant to the gastrointestinal tract. Results revealed the chokeberry products’ ability to inhibit tyrosinase and acetylcholinesterase. Molecular docking confirmed the strong interactions between chokeberry compounds and these enzymes. CONCLUSION: The results indicate the potential of chokeberry products and by-products as valuable resources for pharmaceutical applications.

Strawberry is one of the most favored consumed fresh fruits worldwide. However, the major constraint limiting future sustainable production and sales of strawberries is post-harvest decay. Thus, taking a deep look into the effective preservation measures including pre- and post-harvest techniques to retain freshness and inhibit the pathological spoilage of strawberries in the supply chain is of great significance and necessity. At present, relying solely on post-harvest technology is not enough to fix the aim of strawberry fruit preservation and longer shelf life. On the contrary, pre-harvest treatments could be extend shelf life of strawberry fruit and adapt to the diverse post-harvest environments. This review give the latest pre-harvest treatments, their effects on post-harvest quality and storability of strawberries, and develop the expectation of strawberries pre-harvest methods applicated in the future.

This review give the latest pre-harvest treatments, their effects on post-harvest quality and storability of strawberries, and develop the expectation of strawberries pre-harvest methods applicated in the future.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":"43 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140571282","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}
In the present study, the effects of 60Co-γ irradiation on the diversity of fungal microflora in blueberries during cold storage have been explored in detail. The effects of irradiation on the fungal microflora in blueberries could be observed at the lowest effective dose of 1.0 kGy. The genome library of fungal microflora in blueberries was evaluated by tusing Shannon, Simpson, Chao1, and ACE indices, presenting good coverage of blueberry samples. Principal coordinate analysis clarified the differences in the evolution and clustering of fungi in blueberries under different irradiation levels. The composition and diversity of fungal microflora in blueberries treated with different doses of radiation exhibited significant differences under cold storage of 4°C. However, most of the fungi belonged to the Ascomycota at the phylum. The fungal microflora was relatively stable at the initial stage of cold storage, however, the diversity of fungal species in irradiated blueberries varied greatly in the middle stage around the 15th day. This comprehensive study provides deeper insight about the effects of irradiation on the evolution of fungal microflora in blueberries during cold storage. The findings of this study lay a good foundation for post-harvest storage and preservation of blueberries.

Red raspberries are gaining attention more and more for their nutritional and bioactive components, with potential health effects such as antitumor properties. This review aims to describe the antioxidant activities of red raspberries, emphasizing the role of anthocyanins and ellagitannins as primary contributors among red raspberry polyphenols; it also outlined the connection between red raspberries and their role in inhibiting cancer cell growth by regulating oxidative stress. Numerous studies suggest that red raspberries are able to block cancer cell progression by inhibiting proliferation, migration, and autophagy, as well as regulating the cell cycle, angiogenesis, and DNA damage repair. This review sheds light to the growing evidence supporting antioxidants as a crucial link between fruit consumption and cancer prevention.
