Citrus are sensitive to boron (B)-toxicity. In China, B-toxicity occurs in some citrus orchards. So far, limited data are available on B-toxicity-responsive proteins in higher plants. Thirteen-week-old seedlings of "Sour pummelo" (Citrus grandis) and "Xuegan" (Citrus sinensis) was fertilized every other day until dripping with nutrient solution containing 10 μM (control) or 400 μM (B-toxicity) ...

Anthonomus grandis, the cotton boll weevil, causes severe cotton crop losses in North and South America. Here we demonstrate the presence of starch in the cotton pollen grains and young ovules that are the main A. grandis food source. We further demonstrate the presence of alpha-amylase activity, an essential enzyme of carbohydrate metabolism for many crop pests, in A. grandis midgut. Two alpha...

The propagation of plants for food, timber, medicines and aesthetics has been a principal activity of man for millennia. However, the systematic propagation of plant material for the purposes of conservation has a recent history, probably dating back only a few decades. The propagation and distribution of Torreya taxifolia from wild collected, documented material is one of the largest projects ...

This research aims to investigate the hypoglycemic activity of methanolic extract of Tectona grandis root in alloxan induced diabetic albino rats. A comparison was made between the action of Tectona grandis methanolic extract and a known antidiabetic drug glibenclamide (0.5mg/kg p.o).The methanolic extract of Tectona grandis linn. root was administered orally at different doses to normal rats. ...

Objective: Little knowledge is available on the antimicrobial and antioxidant properties of Coccina grandis fruits and no study has reported on its cell proliferative property. The aim of this study was to examine the antimicrobial, antioxidant and cell proliferative property of fruits of C. grandis. Material and Methods: Fruits of C. grandis were extracted using water; ethanol and acetone by c...

In this study, we analyzed the rickshaw (Owned by Daegu Modern History Museum) measuring each material. The purpose of study was to identify materials in modern cultural assets that utilize a variety complex way, and establish basic data for preservation management. Using portable X-ray fluorescence analyzers (P-XRF), species identification, fiber paint film analysis (microscope observation, SE...

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...
