Targeting Host Defense Mechanism for Enhancing FHB Resistance in Wheat
Project Number: 0500-00053-003-54
Start Date: May 09, 2013
End Date: May 08, 2014
1. Characterize FHB resistance and mycotoxin accumulation in lipoxygenases silenced and overexpressing transgenic wheat lines.
2. Target non-host resistance mechanism for enhancing FHB resistance.
3. Target expression of a Ca2+-binding protein-encoding gene associated with diterpenoid signaling for promoting FHB resistance in wheat.
Utilize these activators and defense/susceptibility genes to enhance FHB resistance in wheat. Three strategies will be utilized: (i) The ectopic expression of defense regulatory genes, (ii) targeting non-host resistance mechanism, and (iii) reducing the level of host susceptibility factors.
