Fruits from many citrus cultivars develop depressed areas in the flavedo (outer part of the peel) and albedo (inner part) following detachment. Although ultrastructural analysis may provide important information about multiple plant responses to stresses and external stimuli at the cell and tissue levels, and despite the proved efficacy of ethylene in reducing peel damage in citrus fruit, cytol...

Alternaria brown spot is a serious disease of fruit and foliage of citrus. This disease caused by Alternaria alternata and causes serious economical losses on susceptible cultivars in Iran. In this research, susceptibility of seven citrus cultivars including Fortune, Orlando tangelo, Mineola tangelo, Page, Clementine, Sour orange and Sweet orange (Thomson) fruits to A. alternata was investigate...

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...

The purpose of this work was 2-fold; first, a molecular/evolutionary characterization of three sucrose synthase genes from citrus, and second, an analysis of their differential expression related to potential physiological function. Three non-allelic genes (CitSUS1, CitSUSA and CitSUS2) encoding sucrose synthase were isolated from citrus fruit (Citrus unshiu Marc.). Phylogenetic analysis from t...

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...

Peels are major byproducts of the juice processing industry. Citrus peels composed two tissues, namely flavedo (outer layer) and albedo (inner layer). Here, were obtained from peel grapefruit cv. ‘Star ruby’, lemon ‘Akragas’, sweet orange cvs. ‘Tarocco’, ‘Sanguinello’ ‘Moro’. Freeze dried investigated for their functional properties, subjected to enzyme-assisted extraction with pectinase cellul...

Cellulase activity increased in separation-zone tissues 1 day after "Valencia" orange (Citrus sinensis [L.] Osbeck) was treated with 20 micrograms per milliliter cycloheximide. Exocellulase was detected only in the separation zones of treated fruit, whereas endocellulase was present in zones from both treated and control fruit. Endocellulase activity in separation-zone tissue of treated fruit w...

Bu çalışmada Türkiye’de yetiştirilmiş Citrus maxima (Şadok) meyvesinin gıda tüketim atığı olarak nitelendirilebilecek dış kabuk ve albedo kısmının antioksidan, fenolik flavonoid madde miktarlarının belirlenmesi amaçlanmıştır. Meyve kısmından ayrılan atık parçalar kurutularak etanol, metanol saf su ile ekstrakte edilmiştir. Dış ekstrelerinden elde edilen sonuçlara göre için en yüksek değer 59.64...
