Abstract

Clear 180-bp nucleosomal DNA laddering in cultured rice cells was induced only by an incompatible strain of Pseudomonas avenae. This supports the current view that the hypersensitive cell death of a plant is programmed cell death. The flagellin-deficient mutant of the incompatible strain did not induce DNA laddering, suggesting that DNA laddering was mediated by incompatible flagellin perception.
