Superoxide and hydrogen peroxide play different roles in the nonhost interaction of barley and wheat with inappropriate formae speciales of Blumeria graminis.

Molecular plant-microbe interactions : MPMI - 1 Mar 2004

Trujillo Marco, Kogel Karl-Heinz, Hückelhoven Ralph

Abstract excerpt

Nonhost resistance of cereals to inappropriate formae speciales of Blumeria graminis is little understood. However, on the microscopic level, nonhost defense to B. graminis is reminiscent of host defense preventing fungal development by penetration resistance and the hypersensitive cell death response (HR). We analyzed histochemically the accumulation of superoxide anion radicals (O2*-) and hydrogen peroxide...
