Disease resistance strategies are major components of modem,sustainable agriculture. Studies on molecular mechanism of wheat disease resistance will provide theoretic bases for disease re- sistance improvement.Our study is focused on the molecular mechanism of powdery mildew resistance. We isolated and studied wheat genes,which may be associated with powdery mildew resistance reac- tion.They are TaMlo,TaLRK,TaEDR1,TaPR-1,TaPR-2,TaPR-5,TaXa(temporary symbol,simi- lar to Oryza sativa disease resistance gene X...
