Abstract

A disease resistance signalling gene in barley, Rar1, has been physically delimited on a YAC clone of 335 kb. It is required for the function of the majority of described race-specific resistance genes to the powdery mildew fungus, Erysiphe graminis f sp hordei, and represents a point of convergence in race-specific resistance reactions. We propose the map-based isolation of Rar1 by utilising chemically- induced mutants in the target gene. A novel transient transformation system in barley will be employed to initiate a functional analysis of Rar1 with respect to subcellular localisation, functional domains, and activation of host cell death. Suppressor mutants of Rar1 have been isolated which will be genetically characterised for their role in down regulating race-specific resistance reactions.
