19 Penicillium spp. are among the major postharvest pathogens of citrus fruit. 20 Induction of natural resistance in fruits constitutes one of the alternatives to 21 chemical fungicides. Here, we investigated the involvement of the 22 phenylpropanoid pathway in the induction of resistance in Navelate oranges by 23 examining changes in the metabolic profile of upon eliciting citrus fruits. By 24...

This study compared the concentration of ascorbic acid between citrus fruits collected from the farm of Kerman in Iran. Determination of ascorbic acid was carried out using a liquid chromatography coupled to a diode array detector, with reverse phase and isocratic elution. The validation parameters showed efficiency, adequate linearity, relative standard deviation values 0.02 % (n=10) for repea...

Antioxidant compounds and the antioxidative activities of new Israeli citrus fruit sweetie [(Oroblanco, pummelo-grapefruit hybrid (Citrus grandis C. paradisi)] were compared with the better-known white grapefruit. Total and free phenols were determined with the Folin–Ciocalteu reagent, phenolic acids (free, esters and glycosides) by HPLC analysis and anthocyanins spectrophotometrically. The ant...

Fruits of sweet orange (Citrus sinensis), a popular commercial Citrus species, contain high concentrations of flavonoids beneficial to human health. These fruits predominantly accumulate O-glycosylated flavonoids, in which the disaccharides [neohesperidose (rhamnosyl-α-1,2-glucose) or rutinose (rhamnosyl-α-1,6-glucose)] are linked to the flavonoid aglycones through the 3- or 7-hydroxyl sites. T...

Background- Cardiovascular diseases, including myocardial infarction, dyslipidaemia and coronary artery pathology, are a major cause of illness and death in Western countries. Therefore, identifying effective therapeutic approaches and their cellular signalling pathways is a challenging goal for medicine. In this regard, several epidemiological studies demonstrate a relationship between the int...

Fruit flies (Diptera: Tephritidae) represent a threat to fruit growing worldwide, mainly the citrus culture, however, biological studies show that fruit flies are not perfectly adapted to this host. This study investigated oviposition of Anastrepha fraterculus (Wiedemann, 1830) and Ceratitis capitata (Wiedemann, 1824) and its relation with the pericarp of citrus fruits. We evaluated the relatio...

Citrus fruits infected with the fungus Penicillium digitatum substantially increase the production of the plant hormone ethylene. In this study, the regulation of ethylene biosynthesis in Citrus sinensis-infected fruits and its putative involvement in an active defence response against P. digitatum infection is examined. Ethylene production is demonstrated as being the result of the co-ordinate...

23 In the present study, two LCYb genes (CitLCYb1 and CitLCYb2) were 24 isolated from Satsuma mandarin (Citrus unshiu Marc.), Valencia orange (Citrus 25 sinensis Osbeck) and Lisbon lemon (Citrus limon Burm.f.) and their functions 26 were analyzed by the color complementation assay in lycopene-accumulating E. 27 coli cells. The results showed that CitLCYb1 and CitLCYb2 shared high identity 28 at...

Citrus fruits have long been valued as part of a nutritious and tasty diet. The flavours provided by citrus are among the most preferred in the world, and it is increasingly evident that citrus not only tastes good, but is also good for people. It is well established that citrus and citrus products are a rich source of vitamins, minerals and dietary fibre (nonstarch polysaccharides) that are es...
