Silicon (Si) can enhance plant defense against biotic and abiotic stresses, but little is known of its possible alleviation of aluminum (Al) stress. In this study, we find out how Si may mediate Al stress based on changes in root morphological parameters, biomass, physiological attributes and concentrations of Al and Si in peanut (Arachis hypogaea L., cv.(More)
As an insect pathogen, the Gram-positive bacterium Bacillus thuringiensis (Bt) has been used widely for insect control for several decades (1). Bacteriophage contamination causes great losses during Bt fermentation, especially those from the lysogenic bacteriophages. Up to 15 to 30% of the total batches, and sometimes up to 50 to 80%, were damaged by(More)
In this study, we report a rapid cloning strategy for large native plasmids via a contig linkage map by BAC libraries. Using this method, we cloned a large plasmid pBMB165 from Bacillus thuringiensis serovar tenebrionis strain YBT-1765. Complete sequencing showed that pBMB165 is 77,627 bp long with a GC-content of 35.36%, and contains 103 open reading(More)
Geographic information systems (GIS) have become increasingly valuable tools in hydrology & hydrodynamic modeling and have been used in the evaluation of integrative development and utilization of water resource in many ways. These may relate to the coupling of hydrology & hydrodynamic models and GIS system, collaborative work of heterogenous(More)
Drought and ultraviolet-B (UV-B) radiation are the most adverse factors for plant growth and productivity. The aim of this study was to compare the effects and interaction of drought and UV-B radiation in the seedlings of maize and soybean. The relative leaf water content was the main factor resulting in reduced growth in response to drought. The(More)
Bacillus thuringiensis CTC, which is identified as serotype H2, serovar. finitimus, is high production of S-layer protein. Due to the property of forming isoporous lattices on the whole cell surface, S-layer protein has been widely used in (nano) biotechnology, biomimetics, biomedicine, especially been employed for displaying many important active proteins.(More)
