Defence signalling pathways in cereals.
The combination of mutational and molecular studies has shed light on the role of reactive oxygen intermediates and programmed cell death in cereal disease resistance mechanisms. Rice Rac1 and barley Rar1 represent conserved disease resistance signalling genes, which may have related functions in animals. The analysis of non-pathogenic Magnaporthe grisea mutants may provide novel tools to study host defence pathways.
