OBJECTIVE: This work aimed to investigate Exogenous application of phenylalanine (Phe; 0, 15 and 30 mM) on berry phenolic compounds, quality and chilling tolerance of ‘Red Sahebi’ grape was examined during 60 days at 1°C. METHODS: Every 15 days (storage durations were 0, 15, 30, 45, and 60 days), approximately 150 gr of grape bunches were sampled randomly from cool chamber for following physicochemical and microbial analysis. RESULTS: Phe-treated grape at 30 mM maintained higher titratable acid, total sensory score, total soluble solid, soluble sugars, organic acids, and antioxidant capacity compared to control grapes. At the end of storage time, 30 mM Phe-treated grapes showed higher flavonols (11% myricetin, 20% quercetin, and 23% kaempferol), flavanols (22% catechin, 34% epicatechin, and 40% epigallocatechin) and anthocyanins (42% malvidin-3-O-glucoside, 30% delphinidin-3-O-glucoside, 25% cyanidin-3-O-glucoside, and 23% pelargonidin-3-O-glucoside) compared to control samples due to lower polyphenol oxidase but higher antioxidant enzyme activities. Also, 30 mM Phe was found to be effective for berry trans-resveratrol and phenolic acid preservation, displayed less fungal decay. The efficiency of Phe on chilling tolerance was monitored by lower rachis browning, electrolyte leakage, and malondialdehyde but higher abscisic acid content. CONCLUSION: Phenylalanine application retained higher TA, TSS, and vitamin C, antioxidant capacity and total sensory score in treated fruits and alleviates chilling injury of table grape during cold storage.","PeriodicalId":15194,"journal":{"name":"Journal of Berry Research","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2022-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41959692","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}

Many researchers have focused on the effect of antioxidant and enzyme inhibitors. OBJECTIVE: The present study aimed to evaluate the active ingredients, in vitro antioxidant and enzyme-inhibitory activity from different parts (root, stem, leaf, and fruit) of wild lingonberry. METHODS: The active ingredients of lingonberry were determined by ultra-performance liquid chromatography-triple quadrupole-mass spectrometry (UPLC-TQ-MS/MS). Antioxidant activities were measured by DPPH, ABTS, FRAP and CUPRAC assays. Principal component analysis (PCA) and agglomerated hierarchical clustering (AHC) were used to analyze the relationship between active ingredients, antioxidant and enzyme-inhibitory activity. RESULTS: Phenolic compounds were significantly higher in leaf and stem. The enzyme inhibitory of the extracts varied observably according to the plant parts. Fruit had the highest acetylcholinesterase (317.67 mg GALAEs/g) and butyrylcholinesterase (346.04 mg GALAEs/g) inhibitory activity, while leaf had the most potent activity on α-amylase (256.59 mg ACAEs/g), α-glucosidase (186.70 mg ACAEs/g) and tyrosinase (42.87 mg KAEs/g). Tyrosinase had strong correlation and similarity with phenolic acids and flavonoids in the correlation analysis and PCA. CONCLUSIONS: 29 active ingredients were detected, including phenolic acids, flavonoids, anthocyanins, and triterpenes. Lingonberry sample to inhibit the activity of tyrosinase was associated with five flavonoids (kaempferol-3-O-galactoside, kaempferol-3-O-β-D-glucosyl (1 ⟶ 2) galactoside, biorobin,,quercetin 3-O-glucoside-7-O-rhamnoside, rutinum) and phenolic acid content (arbutin).

However, research on V. uliginosum is limited, with no literature available to clarify the germplasm resources suitable for breeding. OBJECTIVE: This study aimed to evaluate the contents of total flavonoids (TF), total anthocyanins (TA), and total phenols (TP) in 10 different populations of V. uliginosum from the Changbai Mountains, China, and investigate the correlation between these functional components and spatial distribution. METHODS: The components and contents of TA, TF, and TP were determined using mass spectrometry, high-performance liquid chromatography, and the Folin–Ciocalteu method, respectively. RESULTS: A total of 15 anthocyanins were detected, and the content of Mal-glu, Pet-glu, and Del-glu was the highest among these anthocyanins. The TF and TA and TP contents were highest in the DFHI and LJII populations, respectively, which can be reasonably developed as excellent populations. The TF content of sample DFHI-8, TA content of LJIII-1 and TP content of LJIIII-4 were higher than other samples, which can be used as important breeding germplasm. The content of TF is positively correlated with altitude, while the content of TA and TP is bidirectional, which is positively correlated at 740–838 m and negatively correlated at >838 m.

Mental health outcomes were assessed using the Pittsburgh Sleep Quality Index (PSQI), the Perceived Stress Scale (PSS), the 10-item Center for the Epidemiological Studies of Depression Short Form (CES-D-10) as a screening tool for sleep quality, perceived stress and depressive symptoms, respectively. RESULTS: A significant inverse association between higher anthocyanin-rich fruits intake and occurrence of poor sleep quality, high perceived stress, and depressive symptoms was found. In the most adjusted model, individuals in the highest tertile of anthocyanin-rich fruits were less likely to have poor sleep quality (OR = 0.63, 95% CI: 0.47–0.86), high perceived stress (OR = 0.68, 95% CI: 0.51–0.92), and depressive symptoms (OR = 0.67, 95% CI: 0.49–0.90).

Previously, studies demonstrated the health benefits of morin using human and animal models. Despite its importance as a bioactive compound, the genetic architecture of the morin biosynthetic pathway is still unclear. OBJECTIVE: To understand the genetic architecture of the morin biosynthetic pathway, the following components were analyzed: (1) cis-responsive element (CRE)-mediated regulation, (2) microRNAs (miRNA)-mediated post-transcriptional silencing, and (3) tissue-specific in silico gene expression. METHODS: To understand the genetic architecture of morin biosynthetic pathway, in silico survey was carried out using different web servers (MorusDB, MEME suite, NCBI database, PlantCARE, and psRNATarget) and collected mRNA, protein sequences, and expressed microarray data. TBtools was employed for depicting protein and promoter motifs and the heatmap preparation of tissue-specific expression of genes involved in the morin biosynthesis. RESULTS: The current data mining study highlighted the morin biosynthetic pathway associated genes, namely, phenylalanine ammonia-lyase (MnPAL), chalcone synthase A (MnCSA), chalcone-flavonone isomerase (MnCFI), and flavonoid 3′,5′-hydroxylase (MnFH) are transcriptionally regulated by different growth, development, and stress-responsive CREs. Differential expression profiles how MnPAL (L484_024373) and MnCFI (L484_011241) genes were upregulated across selected tissues. Moreover, miRNA-mediated post-transcriptional silencing was identified.

METHODS:Blueberries were harvested at three ripening stages. Fully ripe fruit was treated with chitosan and kept at room temperature for 5 and 10 days. GC-MS was used to measure organic acids, individual sugars, and sugar derivatives. Gene expression was analysed using qPCR. RESULTS:Elizabeth fruit was less firm than Brigitta fruit, but contained more soluble solids. The sweeter taste of Elizabeth versus Brigitta was due to down-regulated VcINV, VcSPS, and VcADR transcription and increased sucrose concentration. Chitosan inhibited VcADR and VcINV transcription in Elizabeth, but activated these genes in Brigitta after 5 days of storage. CONCLUSIONS:Aldose reductase might be an essential enzyme in blueberry sugar metabolism.
