Excess of copper (>2 mg/L) in drinking water is significantly toxic to human being and ecological environments. Various treatment technologies for copper removal from industrial and municipal waste water effluents has been investigated in past. In the present study batch biosorption studies were carried out for the adsorption of Cu by using natural cheap agrowaste such as peel of Citrus sinensi...

Boron (B) toxicity is observed in some citrus orchards in China. However, limited data are available on the molecular mechanisms of citrus B-toxicity and B-tolerance. Using cDNA-AFLP, we identified 20 up- and 52 down-regulated genes, and 44 up- and 66 down-regulated genes from excess B-treated Citrus sinensis and Citrus grandis roots, respectively, thereby demonstrating that gene expression pro...

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...

Efficacy of essential oils extracted from peel of various citrus species; Citrus reticulata, Citrus sinensis, Citrus paradisi and Citrus grandis were determined against the adults of Callosobruchus chinensis and Tribolium castaneum as well as against the larvae of Trogoderma granarium in order to find out safe alternatives of high toxics. Four concentrations of each oil; 2%, 4%, 6% and 8% were ...

Seedlings of aluminum (Al)-tolerant Citrus sinensis and Al-intolerant Citrus grandis were fertigated daily with nutrient solution containing 0 and 1.0 mM AlCl3●6H2O for 18 weeks. The Al-induced decreases of biomass and root total soluble proteins only occurred in C. grandis, demonstrating that C. sinensis had higher Al-tolerance than C. grandis. Under Al-treatment, C. sinensis roots secreted mo...

Citrus crops are considered to be relatively poor hosts for Queensland fruit fly, Bactrocera tryoni (Froggatt), as for other tephritid species. Australian citrus growers and crop consultants have reported observable differences in susceptibility of different citrus cultivars under commercial growing conditions. In this study we conducted laboratory tests and field surveys to determine susceptib...

The mosquito repellent activity of phytochemical extracts from Peels of five citrus fruit species, Citrus sinensis, Citrus limonum,Citrus aurantifolia, Citrus reticulata and Citrus vitis, was investigated. The volatile phytochemical extracts were obtained from processed air-dried and powdered citrus fruit peels by Soxchlet extraction using Diethyl Ether as solvent. Five different concentrations...

A putative citrus vacuolar processing thiolprotease cDNA (Cit-vac) was isolated from a cDNA library of Citrus fruits (Citrus sinensis L. Osbeck var Washington navel). The cDNA is 58 and 57% identical with vacuolar processing seed proteases from castor bean and soybean, respectively. The Citvac sequence shows a typical signal peptide for entering into the endoplasmic reticulum and two glycosylat...

Seedlings of aluminum-tolerant 'Xuegan' (Citrus sinensis) and Al-intolerant 'sour pummelo' (Citrus grandis) were fertigated for 18 weeks with nutrient solution containing 0 and 1.2 mM AlCl₃·6H₂O. Al toxicity-induced inhibition of photosynthesis and the decrease of total soluble protein only occurred in C. grandis leaves, demonstrating that C. sinensis had higher Al tolerance than C. grandis. Us...
