“…The losses caused by CCN can be up to 30-100% in some wheat fields [3,4]. The damage caused by CCN can be mitigated through several methods, including crop rotation [5], application of nematicide [6], cultural practice [7], host resistance [8,9], etc. Of these methods, incorporating resistance genes into wheat cultivars and breeding resistant lines is considered to be the most cost-effective control measure for reducing nematode populations.…”

Characterization and expression profiling of a novel cereal cyst nematode resistance gene analog in wheat

et al. 2008

-Based on the conserved regions of known resistance genes, an NBS-LRR-type CCN resistance gene analog was isolated from the CCN resistant E-10 near isogenic lines (NILs) of wheat, designated as CreZ (GenBank accession number: EU327996). It contained a complete ORF that was 2775 bp in length and encoded 924 amino acids. Sequence comparison indicated that it shared 92% nucleotide and 87% amino acid identity with those of the known CCN-resistance gene Cre3 and had similar characteristic conserved motifs to those in other established NBS-LRR disease resistance genes. The expression profiling of CreZ indicated that it was specifically expressed in the roots of resistant plants and real-time PCR analysis demonstrated that expression levels drastically increased when the plants were inoculated with cereal cyst nematodes. It could be inferred, then, that CreZ belongs to the NBS-LRR resistance gene family and is a candidate gene for potential resistance to the cereal cyst nematode.

“…A resistance locus, Cre , has been identified [8,15] and nine genes resistant to CCN (designated Cre1 , 2,3,4,5,6,7,8 , and R ) have been described, in which Cre1 and Cre8 were derived directly from common wheat [16][17][18][19][20][21][22][23][24]. The Cre3 locus, which was derived from Ae.…”
