Abstract:
... The USDA’s Animal and Plant Health Inspection Service (APHIS) is one of three agencies that govern the importation, interstate movement, or environmental release of certain genetically engineered (GE) organisms. APHIS regulations are in 7 CFR part 340, originally issued in 1987 (https://www.aphis.usda.gov/biotechnology/downloads/7_cfr_340.pdf) and based on the premise that a GE crop could pose a p ...

Abstract:
... BACKGROUND: Clostridium perfringens, a gram-positive, anaerobic, rod-shaped bacterium, is the third leading cause of human foodborne bacterial disease and a cause of necrotic enteritis in poultry. It is controlled using antibiotics, widespread use of which may lead to development of drug-resistant bacteria. Bacteriophage-encoded endolysins that degrade peptidoglycans in the bacterial cell wall are ...

In the past few decades, our understanding of the composition, biosynthesis, assembly, degradation, and regulation of chitinous structures has increased. Many chemicals have been developed that target chitin biosynthesis (benzoyphenyl ur ...

Abstract:
... Fusarium head blight (FHB) is one of the main fungal diseases of grain crops such as wheat, barley and maize. The FHB species complex produces mycotoxins that cause quality and yield reductions, as well as human and animal health risks. Resistance breeding, integrated with chemical and or cultural control practices has the potential for sustainable control of FHB. However, breeding for FHB resista ...
