 Abstract: The identification of two Arabidopsis thaliana genes involved in determining recessive resistance to several strains of the causal agent of bacterial wilt, Ralstonia solanacearum, is reported. Dominant (RRS1S) and recessive (RRS1-R) alleles from susceptible and resistant accessions encode highly similar predicted proteins differing in length and which present a novel structure combining domains found in plant Toll-lL-1 receptor-nucleotide binding siteleucin-rich repeat resistance proteins and a WRKY motif characteristic of some plant transcriptional factors. Although genetically defined as a recessive allele, RRS1-R behaves as a dominant resistance gene in transgenic plants. Sequence analysis of the RRS1 genes present in two homozygous intragenic recombinant lines indicates that several domains of RRS1-R are essential for its resistance function. Additionally, RRS1-R-mediated resistance is partially salicylic acid- and NDR1-dependent, suggesting the existence of similar signaling pathways to those controlled by resistance genes in specific resistance.
