Citrus, as one of the globally important fruit trees, has been an object of interest for understanding genetics and evolutionary process in fruit crops. Meta-analyses of 19 Citrus species, including 4 globally and economically important Citrus sinensis, Citrus clementina, Citrus reticulata, and 1 Citrus relative Poncirus trifoliata, were performed. We observed that codons ending with A- or T- a...

In previous migration studies, the presence of citrus pollen on adult Helicoverpa zea (Boddie), in conjunction with synoptic weather systems and 72-h backtrack trajectories, were used to identify source zones of migrants. However, data are lacking regarding the retention of citrus pollen for 72-h by H. zea adults. We exposed laboratory-reared and feral H. zea adults to citrus blooms for a 12-h ...

We investigated the determination of N-methylcarbamate pesticides and their metabolites in agricultural products by HPLC with post-column fluorescence detection after clean-up with an SPE cartridge. The homogenate of agricultural products was extracted with acetone. The crude extract was partitioned between 5% sodium chloride solution and dichloromethane, and the dichloromethane layer was conce...

Citrus canker caused by Xanthomonas citri subsp. citri (Xcc) is one of the most important bacterial diseases of citrus. Because citrus canker is not found in many countries including European Union and Australia, Xcc is strictly regulated in order to prevent its spread. In this study, the effects of X-irradiation on Xcc growth either in the suspension or on the surface of citrus fruits were inv...

the red flour beetle, tribolium castaneum (herbst), is one of the most destructive pests attacking stored grain products all over the world. serious problems assossiated with using synthetic chemical insecticides have strongly demonstrated the need for applying alternative safe compounds such as plant essential oils. the present experiment was conducted to evaluate fumigant toxicity of essentia...

Polymethoxyflavonoids (PMFs) almost exclusively exist in citrus plants. In recent years, there has been increasing and particular interests in the exploration of the health benefits associated with PMFs. PMFs are reported to exhibit a broad spectrum of biological activities, such as anti-inflammatory, anti-carcinogenic, anti-tumor, anti-viral, anti-thrombogenic and anti-atherogenic properties. ...

Examination of the dried peel powder of Citrus kawachiensis, one of the citrus products of Ehime, Japan, showed that it contained naringin (NGIN; 44.02 ± 0.491 mg/g), narirutin (NRTN; 4.46 ± 0.0563 mg/g), auraptene (AUR; 4.07 ± 0.033 mg/g), and 3,5,6,7,8,3',4'-heptamethoxyflavone (HMF; 0.27 ± 0.0039 mg/g). When this dried peel powder was orally preadministered at the dose of 1.2 or 2.4 g/kg/day...
