The cpr5 mutant of Arabidopsis expresses both NPR1-dependent and NPR1-independent resistance.

The Plant cell - 1 Sept 1997

Bowling S A, Clarke J D, Liu Y, Klessig D F, Dong X

Abstract excerpt

The cpr5 mutant was identified from a screen for constitutive expression of systemic acquired resistance (SAR). This single recessive mutation also leads to spontaneous expression of chlorotic lesions and reduced trichome development. The cpr5 plants were found to be constitutively resistant to t...
