Summary Strawberry ( F ragaria × ananassa ) fruits contain high concentrations of flavonoids. In unripe strawberries, the flavonoids are mainly represented by proanthocyanidins PA s), while in ripe red‐coloured anthocyanins also accumulate. Most structural genes leading to biosynthesis strawberry have been characterized, but no information is available on their transcriptional regulation. A rabidopsis thaliana expression biosynthetic specifically induced a ternary protein complex, composed t...
An electrochemical study of lyophilized blueberry (Vaccinium corymbosum L.) and raspberry (Rubus idaeus fruits was carried out using microparticulate deposits from ethanolic extracts in contact with different aqueous electrolytes. This voltammetry is dominated by the oxidation anthocyanins. It hypothesized that under conditions generation reactive oxygen species (ROS), new anthocyanin-derived high antioxidant capacity are formed over a wide pH range. In case ROS-activated anthocyanins,...
C-repeat/dehydration-responsive element binding factors (CBF/DREB) are transcription which play a role in improving plant cold stress resistance and recognize the DRE/CRT promoter of set regulated genes. Dehydrins (DHNs) proteins that accumulate plants response to stress, present, some cases, CBF/DREB recognition sequences their promoters activated by members this factor family. The application 3-day gaseous treatment with 20kPa CO2 at 0ºC table grapes cv. Autumn Royal maintained quality...
Anthocyanins contribute to the appearance of fruit by conferring them a red, blue or purple colour. In food context, they have also been suggested promote consumer health. tomato tissues, such as hypocotyls, stems and fruits, various anthocyanins accumulate. These molecules characteristic patterns modification, including hydroxylations, methylations, glycosylations acylations. The genetic basis for many these modifications has not fully elucidated, nor their role in functioning anthocyanins....
Table grapes (Vitis vinifera cv. Cardinal) are highly perishable and their quality deteriorates during postharvest storage at low temperature mainly because of sensitivity to fungal decay senescence rachis. The application a 3-day CO2 treatment (20 kPa + 20 O2 60 N2) 0ºC reduced total retained fruit in early late-harvested table storage. In order study the transcriptional responsiveness high levels first stage how maturity affect these changes, we have performed comparative large-scale...
Raspberries (Rubus idaeus L.) are valued as both a food source and medicinal plant, with expanding production driven by premium market demand. Primocane varieties, such “Regina” prized for their ability to produce two harvests per year, offering extended availability into autumn providing significant commercial benefit. Their high polyphenol content, particularly in anthocyanins flavonoids, contributes antioxidant health properties. However, extraction quantification influenced factors...
Within the myrtle (Myrtus communis L.) species, different genotypes may produce dark-blue berries or white depending on peel color upon ripening. One cultivar and one were used to study molecular mechanisms underlying flavonoid biosynthesis. The relative expression levels of common (PAL, CHS, CHI, DFR LDOX) specific (FLS, ANR, LAR UFGT) genes analyzed during fruit development by means quantitative real-time polymerase chain reaction (RT-qPCR). Moreover, anthocyanin content was determined, it...
Ethylene response factors (ERFs) play an important role in plants by regulating defense through interaction with various stress pathways. After harvest, table grapes (Vitis vinifera L.) are subject to a range of problems associated postharvest storage at 0ºC, such as fungal attack, water loss and rachis browning. The application 3-day high CO2 treatment maintained fruit quality activated the induction transcription belonging different families ERF. In this paper, we have isolated five...
Gene expression of a class I chitinase (Vcchit1b) in the skin table grapes was analyzed as molecular marker for changes induced at low temperature and also to study effect high CO(2) levels modulating transcript 0 degrees C. An active recombinant VcCHIT1b overexpressed Escherichia coli, protein produced insoluble inclusion bodies, it solubilized refolded. The purified showed an optimum pH 6.0 50 C, retaining activity -10 Purified exerted vitro antifungal against Botrytis cinerea....
Abstract BACKGROUND In this study, we analyzed the effect of application high levels CO 2 (20 kPa + 20 O 60 N ) for 3 days at low temperature on a white table‐grape cultivar (Superior Seedless) in comparison with black one (cv. Autumn Royal) terms quality parameters. We also used solid‐state voltammetry methodology to analyze 3‐day gaseous treatment berry tissues from both cultivars first stage storage. determined role non‐enzymatic (total phenols, total anthocyanins, and antioxidant...
