Fusarium Ratings in Ontario Winter Wheat Performance Trial (OWWPT) Using an Index that Combines Fusarium Head Blight Symptoms and Deoxynivalenol Levels
breeding mycotoxins resistance
2014/2/25
Fusarium head blight (FHB) is one of the most serious diseases of wheat (Triticum aestivum L.). FHB reduces grain yield and quality, and the fungus produces mycotoxins, such as deoxynivalenol (D...

2009/10/21
Keeping track of time is one of the brain's most important tasks. As the brain processes the flood of sights and sounds it encounters, it must also remember when each event occurred. But how does that...
Load-dependent sliding direction change of a myosin head on an actin molecule and its energetic aspects: Energy borrowing model of a cross-bridge cycle
myosin ATPase enthalpy production molecular machinery loose coupling Hill’s Formulation
