Maize (Zea mays L.) is susceptible to infection by Fusarium verticillioides through autoinfection and alloinfection, resulting in diseases and contamination of maize kernels with the fumonisin mycotoxins. Attempts at controlling this fungus are currently being done with biocontrol agents such as bacteria, and this includes bacterial endophytes, such as Bacillus mojavensis . In addition to produ...

BACKGROUND Biological methods of polycyclic aromatic hydrocarbons (PAH) contamination elimination typically involve the transformation of contaminants to non-toxic materials by microorganisms and plants and appear to be the most effective methods available. METHODS In this study, Bacillus licheniformis and Bacillus mojavensis isolated from oil-contaminated soils were inoculated onto Festuca a...

Salinity is a major abiotic stress that reduces crop productivity in arid and semiarid soils. About 25% of the country's arable land is affected by different levels of salt. A considerable part of this land is under wheat cultivation each year as the country's most important crop. ACC deaminase producing bacteria increase plant resistance to stress condition by reducing stress ethylene in a var...

Gram-positive endophytic bacteria are difficult to transform. To study the interactions between Bacillus mojavensis and maize, a method was developed to transform the microbe by electroporation with three integration plasmids expressing green, cyan and yellow fluorescent proteins (GFP variants). GFP Transformations were verified by antibiotic selection, microscopy and amylase deficiency, based ...

Botryosphaeria canker of Quercus suber (causal agent: Diplodia corticola) poses a major threat for cork production along the western Mediterranean Basin. Infection by D. corticola induces cankers, which reduce tree vigour and compromise phellem regeneration. European policies in forest health advise use environmentally friendly methods, such as biocontrol, rather than chemicals natural stands. ...

The cactophilic Drosophila mojavensis species group living in the deserts and dry tropical forests of the southwestern United States and Mexico provides a valuable system for studies in diversification and speciation. Rigorous studies of the relationships between host races of D. mojavensis and the relationships among the members of the species group (D. mojavensis, Drosophila arizona, and Dros...
