Abstract

Disease resistance in plants is often controlled by a gene-for-gene mechanism in which avirulence ( avr ) gene products encoded by pathogens are specifically recognized, either directly or indirectly, by plant disease resistance ( R ) gene products. Members of the NBS-LRR class of R genes encode proteins containing a putative nucleotide binding site (NBS) and carboxyl-terminal leucine-rich repeats (LRRs). Generally, NBS-LRR proteins do not contain predicted transmembrane segments or signal peptides, suggesting they are soluble cytoplasmic proteins. RPM1 is an NBS-LRR protein from Arabidopsis thaliana that confers resistance to Pseudomonas syringae expressing either avrRpm1 or avrB . RPM1 protein was localized by using an epitope tag. In contrast to previous suggestions, RPM1 is a peripheral membrane protein that likely resides on the cytoplasmic face of the plasma membrane. Furthermore, RPM1 is degraded coincident with the onset of the hypersensitive response, suggesting a negative feedback loop controlling the extent of cell death and overall resistance response at the site of infection.
