Bud mutations often arise in citrus. The selection of mutants is one of the most important breeding channels in citrus. However, the molecular basis of bud mutation has rarely been studied. To identify differentially expressed genes in a spontaneous sweet orange [C. sinensis (L.) Osbeck] bud mutation which causes lycopene accumulation, low citric acid, and high sucrose in fruit, suppression sub...

To elucidate a mechanistic basis for the reductions in chlorophyll (Chl) and inhibition of CO2 assimilation (ACO2 ) in nitrogen (N) starved citrus leaves, changes in Chl concentration and net gas exchange rates were examined together with chloroplast ultrastructure in N-deficient (125 mmol N m−2) and N-sufficient (286 mmol N m−2) citrus leaves. Two-year-old ‘Hamlin’ orange (Citrus sinensis L.) ...

Yeast is one of the most important ingredients in bread making and, it may be isolated from local fruits such as sweet oranges a commercial yeast substitute. This research aimed to isolate orange (Citrus sinensis L) that used improver. The method was endophytic isolation on rind and flesh citrus fruits. It identified macroscopically, microscopically analyzed for carbohydrate fermentation, growt...

مرکبات شمال از نظر کیفیت و تطابق با ذائقه ایرانیان از اهمیت کشاورزی و تجاری برخوردارند. بهبود کیفیت این محصولات از اهداف مهم کشاورزان و دانشمندان این رشته است. در پژوهش حاضر، پاسخ دو گونه از مرکبات، نارنج (Citrus aurantium) و سیترنج (هیبریدی از پرتقال شیرین و نارنج Citrus sinensis x Poncirus trifoliata) به تنش سرما از طریق بررسی وجود پروتئین ضد یخ و تغییر پراکسیداسیون لیپیدها در گونه‌های مرکبات...

The bacterium Xylella fastidiosa is the causal agent of citrus variegated chlorosis (CVC) and has been associated with important losses in commercial orchards of all sweet orange [Citrus sinensis (L.)] cultivars. The development of this disease depends on the environmental conditions, including the endophytic microbial community associated with the host plant. Previous studies have shown that X...

The spatial distribution of the three principal species of sharpshooter (Dilobopterus costalimai Young, Acrogonia sp. e Oncometopia facialis Signoret), vectors of Xylella fastidiosa causal agent of Citrus Variegated Chlorosis, was studied by using geostatistics. The evaluations were carried out in a commercial ‘Pera’ sweet orange (Citrus sinensis [L.] Osb.) grove budded on Rangpur lime (Citrus ...

The abundance and spatial dispersion of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) were studied in 34 grapefruit (Citrus paradisi Macfad.) and six sweet orange [Citrus sinensis (L.) Osbeck] orchards from March to August 2006 when the pest is more abundant in southern Texas. Although flush shoot infestation levels did not vary with host plant species, densities of D. citri eggs, nymphs, an...
