An SSR from the leucine-rich repeat region of the rose Rdr1 gene family is a useful resistance gene analogue marker for roses and other Rosaceae

The Cre3 gene confers a high level of resistance to the root endoparasitic nematode Heterodera avenae in wheat. A DNA marker cosegregating with H. avenae resistance was used as an entry point for map-based cloning of a disease resistance gene family at the Cre3 locus. Two related gene sequences have been analysed at the Cre3 locus. One, identified as a cDNA clone, encodes a polypeptide with a nucleotide binding site (NBS) and a leucine-rich region; this member of the disease resistance gene family is expressed in roots. A second Cre3 gene sequence, cloned as genomic DNA, appears to be a pseudogene, with a frame shift caused by a deletion event. These two genes, related to members of the cytoplasmic NBS – leucine rich repeat class of plant disease resistance genes were physically mapped to the distal 0.06 fragment of the long arm of wheat chromosome 2D and cosegregated with nematode resistance.Key words: cereal cyst nematode, disease resistance genes, nucleotide-binding site, leucine-rich repeat.

Entry Points

In this study, resistance gene analogs (RGAs) which were isolated from monocot crop species (wheat, barley, maize and rice) and contained conserved sequence motifs found within the nucleotide binding site - leucine rich repeat (NBS-LRR) class of resistance genes, were used to assess their distribution in the wheat genome. The RGAs showed 30-70% amino acid identity to a previously isolated monocot NBS-LRR sequence from the Cre3 locus for cereal cyst nematode (CCN) resistance in wheat. We used the RGAs as probes to identify and map loci in wheat using recombinant inbred lines of an international Triticeae mapping family. RGA loci mapped across all seven homoeologous chromosome groups of wheat. This study demonstrated that the RGA mapping approach provides potential entry points toward identifying resistance gene candidates in wheat.Key words: wheat, disease resistance genes, nucleotide binding site, leucine rich repeat, resistance gene analogs.
