Research Project:
FACTORS AND MECHANISMS FAVORING DEOXYNIVALENOL PRESENCE IN ASYMPTOMATIC WHEAT
Project Number: 0500-00053-002-35
Project Type:
Grant
Start Date: May 23, 2005
End Date: May 22, 2009
Objective:
Understand the environmental conditions and cellular mechanisms that favor development of significant levels of deoxynivalenol (DON) in wheat grain that is apparently healthy or shows only low levels of disease.
Approach:
Evaluate the role of air temperature and timing of infection on development of asymptomatic kernels containing >2 ppm DON; Determine if translocation of DON within the wheat head from infected to uninfected spikelets can result in DON levels >2 ppm in healthy kernels and to see if certain cultivars favor translocation and DON accumulation at sites distant from the fungus.
