Here, we provide the data from a comparative proteomics approach used to investigate the response of boron (B)-tolerant 'Xuegan' (Citrus sinensis) and B-intolerant 'Sour pummelo' (Citrus grandis) leaves to B-toxicity. Using two-dimensional gel electrophoresis (2-DE) technique, we identified 50 and 45 protein species with a fold change of more than 1.5 and a P-value of less than 0.05 from B-toxi...

Examination of 640 natural isolates of Bacillus thuringiensis showed that the 58 strains (9%) whose supernatants were toxic to Anthonomus grandis (Coleoptera: Curculionidae) produced between 10 and 175 micro g of beta-exotoxin I per ml. We also found that 55 (46%) of a sample of 118 strains whose culture supernatants were not toxic to A. grandis nevertheless produced between 2 and 5 micro g/ml....

Pulvinaria urbicola, a pulvinariine soft scale was recorded for the first time on Christmas Island (Indian Ocean) in June 2011. A broad host plant generalist, Pu. urbicola excretes honeydew and is commonly tended by ants, including invasive Anoplolepis gracilipes and Pheidole megacephala. Pu. urbicola is implicated in dieback of forest dominated by Pisonia grandis (Nyctaginaceae) on many Indo-p...

Lipid peroxidation and root elongation of Eucalyptus grandis × Eucalyptus camaldulensis were studied under stress conditions in response to aluminum (Al), a metal known to limit agricultural productivity in acidic soils primarily due to reduced root elongation. In Brazil, the Grancam 1277 hybrid (E. grandis × E. camaldulensis) has been planted in the "Cerrado", a region of the country with a wi...

Seedlings of "Xuegan" (Citrus sinensis) and "Sour pummelo" (Citrus grandis) were irrigated daily with a nutrient solution at a pH of 2.5, 3, 4, 5, or 6 for 9 months. Thereafter, the following responses were investigated: seedling growth; root, stem, and leaf concentrations of nutrient elements; leaf gas exchange, pigment concentration, ribulose-1,5-bisphosphate carboxylase/oxygenase activity an...

Se evaluó el contenido de catequina en cortezas las especies forestales Pinus patula, oocarpa y Eucaliptus grandis, cultivadas Departamento del Cauca-Colombia. Los extractos etanólicos se obtuvieron evaluando mejores condiciones tamaño partícula, tiempo agitación, relación disolvente-corteza, temperatura agitación. El determinó usando cromatografía líquida alta resolución (HPLC) con detector ul...

BACKGROUND To determine the antitumor effects and its mechanism of n-butanol fraction from aril of Torreya grandis (BFAT) on H22 mice models of liver cancer. MATERIALS AND METHODS Sixty ICR male mice were used to establish H22 mice models of liver cancer and then randomly divided into six groups, the normal control group, the model control group, the positive group (cyclophosphamide [CTX]), t...

RNA interference (RNAi) approaches have been applied as a biotechnological tool for controlling plant insect pests via selective gene down regulation. However, the inefficiency of RNAi mechanism in insects is associated with several barriers, including dsRNA delivery and uptake by the cell, dsRNA interaction with the cellular membrane receptor and dsRNA exposure to insect gut nucleases during f...
