Abstract: BACKGROUND: Kiwifruit plants are extremely sensitive to hail storms. Black anti-hail nets are the most frequently used in kiwifruit culture, to protect both the plant and current as well as future production. OBJECTIVE: The present trial aimed to assess if the black hail net could also serve as an amelioration agent against high temperature and irradiance during the summer months. METHODS: The photosynthetic capacity, the yield, and fruit quality (carbohydrates, organic acids, phenolic compounds, and antioxidant capacity) of “Hayward” kiwifruit cultivar, both at harvest and after three months of storage were evaluated.…RESULTS: Photosynthetic capacity under the net was slightly higher compared to control, while leaf temperature was always lower during the summer and autumn. The yield was significantly enhanced under the net, while the fruits exhibited higher titratable acidity, organic acids, and ascorbic acid concentration. After the storage, fruits produced from vines grown under net still had higher organic acid content, as well as total soluble solids but lower antioxidant capacity compared to control. CONCLUSIONS: Net installation above kiwifruit canopy seems to alleviate the effects of high temperature and heat load on kiwifruit vines, under saturating light intensity, inducing higher yields with good fruit quality.
Abstract: BACKGROUND: Long terminal repeat (LTR) retrotransposons are widespread in plant genomes and play a large role in the generation of genomic variation. Despite this, their identification and characterization remains challenging, especially for non-model genomes. Hence, LTR retrotransposons remain undercharacterized in Vaccinium genomes, although they may be beneficial for current berry breeding efforts. OBJECTIVE: Exemplarily focusing on the genome of American cranberry (Vaccinium macrocarpon Aiton), we aim to generate an overview of the LTR retrotransposon landscape, highlighting the abundance, transcriptional activity, sequence, and structure of the major retrotransposon lineages. METHODS: Graph-based clustering of whole genome…shotgun Illumina reads was performed to identify the most abundant LTR retrotransposons and to reconstruct representative in silico full-length elements. To generate insights into the LTR retrotransposon diversity in V. macrocarpon , we also queried the genome assembly for presence of reverse transcriptases (RTs), the key domain of LTR retrotransposons. Using transcriptomic data, transcriptional activity of retrotransposons corresponding to the consensuses was analyzed. RESULTS: We provide an in-depth characterization of the LTR retrotransposon landscape in the V. macrocarpon genome. Based on 475 RTs harvested from the genome assembly, we detect a high retrotransposon variety, with all major lineages present. To better understand their structural hallmarks, we reconstructed 26 Ty1-copia and 28 Ty3-gypsy in silico consensuses that capture the detected diversity. Accordingly, we frequently identify association with tandemly repeated motifs, extra open reading frames, and specialized, lineage-typical domains. Based on the overall high genomic abundance and transcriptional activity, we suggest that retrotransposons of the Ale and Athila lineages are most promising to monitor retrotransposon-derived polymorphisms across accessions. CONCLUSIONS: We conclude that LTR retrotransposons are major components of the V. macrocarpon genome. The representative consensuses provide an entry point for further Vaccinium genome analyses and may be applied to derive molecular markers for enhancing cranberry selection and breeding.
Abstract: Dioecism and an extended juvenile phase of 3–7 years in kiwifruit hinder the progress in breeding new cultivars. The identification of fruit-bearing females at an early stage of growth is crucial for breeders. Consequently, molecular markers have become a key tool for identifying female and male plants at an early stage of development. Several efforts were made to identify PCR-based sex linked markers in Actinidia ; however, those markers are characterized by a highly polymorphic nature affecting the result of the screening reliability, suggesting the need of more suitable, stable markers, characterized by a consistent transferability among genotypes and species.…The main goal of this work was to develop a method for the ultimate discrimination of females from male plants at an early stage of growth using sex-linked markers. We developed an Early Sex Discrimination molecular Test (ESD Test) that allows the discrimination of male and female plants using a simple PCR amplification test. We demonstrate that the test could unequivocally identify the gender of an unknown sample both in the most commercially important species A. chinensis and in further 13 Actinidia species tested with the exception of Actinidia latifolia , where markers fail in gender discrimination. Male genotypes could be easily identified and discarded reducing the cost of a breeding program.
Abstract: Metabolomics, one of the most recent additions to the systems biology toolkit, has been used to study the metabolism and physiology of living organisms. In the field of food research, metabolomics has lately gained popularity as a technique for determining the quality, processing, and safety of raw materials and final food products, as well as for identifying biomarkers linked to food intake and disease. This review aimed to provide an overview of the current understanding of the analytical techniques used for metabolomics and their application to berries with a special emphasis on the in vivo studies. Specifically, identification of…biomarkers of biological activity and in vivo metabolites of berries using metabolomics approach is covered.

Abstract: BACKGROUND: Berberine, extracted from Berberis vulgaris, is one of the well-known natural antioxidant sources. OBJECTIVE: Optimizing the berberine extraction conditions from the whole Barberry plant and microencapsulation of the optimized extract to be used as a bioactive ingredient in functional orange juice. METHODS: Seventeen extraction processes were designed to determine an optimized method for producing an ethanol/water extract with maximum yield, safety, and antioxidant properties. The optimal extract was microencapsulated by complex coacervation using tragacanth/gelatin and then spray-dried. The selected microcapsules based on morphology, particle size, and solubility were added to orange juice, and the…physical and sensory properties of the functional drink, as well as the kinetic release models, were analyzed. RESULTS: An optimal extract with 82%antioxidant activity was prepared using a 75%ethanol/water ratio and an extraction time of 0.5 h at 22.3°C. Spherical-shaped microcapsules could create a desirable cloudy appearance with good stability in the pH of orange juice. The kinetics of the berberine release revealed an initial burst phase followed by a prolonged one, which would appeal to consumers’ sensory perceptions. CONCLUSIONS: The excellent compatibility between berberine and orange juice provides a potential capacity to fortify a high-consumption drink with a phytonutrient presented in a berry fruit.
Abstract: BACKGROUND: ×Sorbaronia mitschurinii (also known as Aronia mitschurinii ) is an intergeneric hybrid of×Sorbaronia fallax and Aronia melanocarpa . ×S. mitschurinii berry is a rich source of phytochemicals such as flavonoids and anthocyanins, which have a broad range of health benefits and a great geroprotective potential. OBJECTIVES: The goal of the present study was to investigate the geroprotective effects of Sorbaronia berry ethanolic extract (SBE) in Drosophila melanogaster and whether these effects depend on the concentration of SBE, duration of treatment, age, and sex. METHODS: SBE was used to supplement a diet…of Drosophila imagoes throughout life, during 2 weeks after the imago hatching, and from 4 to 6 weeks of age. The relationship between the SBE effects on lifespan, stress resistance and the expression of stress response genes were examined. RESULTS: SBE treatment at 1-2 and 4-6 weeks of life increased the lifespan, while treatment throughout life reduced lifespan. SBE treatment increased Drosophila resistance to oxidative stress and starvation, but not to hyperthermia. A statistically significant effect of SBE treatment on the expression level of per , keap1 , hif1 , hsp27 , hsp68 , hsp83 , and sirt1 genes in flies of both sexes and on sod1 expression only in female flies was demonstrated. CONCLUSIONS: The observed relationship between SBE concentration and lifespan effects suggests that the life-extending effect of SBE may be associated with the mechanism of hormesis.
Abstract: BACKGROUND: Highbush blueberry (Vaccinium corymbosum ), the species primarily grown in the state of Washington, U.S., is relatively cold hardy. However, low temperatures in winter and early spring can still cause freeze damage to the buds. OBJECTIVE: This study intended to explore hyperspectral imaging (HSI) for detecting freeze induced bud damage. Blueberry buds (c.v. Duke) were collected over two seasons and tested in the laboratory to detect damage at four typical phenological stages. METHODS: The HSI data was acquired via line scan HSI system with spectral wavelength ranging from 517 to 1729 nm for buds grouped into…either normal or injured mortalities. The successive projection algorithm was employed for pertinent feature wavelength selection. Analysis of variance and linear regression were then applied for evaluating sensitivity of feature wavelengths. RESULTS: Overall, five salient wavelengths (706, 723, 872, 1384, and 1591 nm) were selected to detect bud freeze injury. A quadratic discriminant analysis method-based analysis verified reliability of these five wavelengths in bud damage detection with overall accuracy in the ranges of 64 to 82%for the test datasets of each stage in two seasons. CONCLUSIONS: This study indicated potential of optical sensing to identify the injured buds using five salient wavelengths.

Abstract: BACKGROUND: Haskap (Lonicera L.) is as a new perspective berry species for growing in temperate region climate. According to nowadays knowledge haskap is absolutely self-sterile species hence the studies on pollination mode are required. OBJECTIVE: The aim was to evaluate new haskap cultivars of Canadian and Russian origin in terms of their matching for cross-pollination. METHODS: The overlapping of flowering time of cultivars for mutual cross pollination was selected. The effectiveness of pollination was assessed: in terms of pollen tube overgrowth through the pistil tissue and the quality of set fruit. RESULTS: The…Russian cultivars bloomed much earlier than the Canadian cultivars. The stigma is most receptive in the freshly open flower stage and directly after the anther burst. The minimum qualitatively acceptable weight of a berry is 1 g, which corresponds to the formation of about 6 seeds in the fruit. The most compatible pairs of cultivars were: ‘Aurora’×‘Jugana’, ‘Aurora’×‘Sinij Utes’ and ‘Aurora’×‘Vostorg’. CONCLUSION: The Russian cultivars bloomed much earlier than the Canadian cultivars, the stigma is most receptive in the freshly open flower, minimum qualitatively acceptable weight of berry is 1 g (what represents 6 seeds in fruit), best mutual pollinating cultivars are the cultivars within the same breeding group (Russian x Russian and Canadian x Canadian)
Abstract: BACKGROUND: R2R3-MYB transcription factor (TF) family plays important roles in various biological processes in many plants, especially in the regulation of plant flavonoid accumulation. The fruit of Lonicera caerulea contains abundant anthocyanin. OBJECTIVE: The R2R3-MYB TF family was systematically analyzed according to the RNA-seq data, and the R2R3-MYB candidate genes that were involved in anthocyanin biosynthesis in the fruit of Lonicera caerulea were screened. METHODS: The R2R3-MYB TFs in Lonicera caerulea were identified, and the physical and chemical properties, protein conserved sequence alignment and motifs of each R2R3-MYB TFs were analyzed using…bioinformatics methods. The expression levels of these genes and anthocyanin levels in different tissues and different developmental stages of fruit were determined by RT-qPCR and pH shift method. RESULTS: A total of 59 genes encoding R2R3-MYB TFs in Lonicera caerulea were identified and clustered into 20 subgroups (C1 to C20) based on the relationship to AtR2R3-MYBs. Expression profiles showed that the expression of CL6086 and CL552 in fruit were higher than other tissues, and upregulated in the veraison fruit compared to the green ripe fruit. As the expression of the two genes was concurrent with the anthocyanin content, and showed high correlation with anthocyanin biosynthetic structural genes, they were considered as closely related to anthocyanin biosynthesis in the fruit. CONCLUSION: The results provide a systematic analysis of LcR2R3-MYBs, and the foundation for further molecular mechanisms research of anthocyanin biosynthesis regulated by R2R3-MYB in the fruit of Lonicera caerulea .
