文摘

The indica rice cultivar, Teqing, shows a high level of resistance to rice stripe virus (RSV). It is believed that this resistance is controlled by the gene, qSTV11 TQ . For positional cloning of the resistance gene, a set of chromosome single segment substitution lines (CSSSLs) was constructed, all of which had the genetic background of the susceptible japonica cultivar, Lemont, with different single substituted segments of Teqing on chromosome 11. By identifying the resistance of the CSSSLs-2006 in a field within a heavily diseased area, the resistance gene qSTV11 TQ was mapped between the markers Indel7 and RM229. Furthermore, in that region, six new markers were developed and 52 subregion CSSSLs (CSSSLs-2007) were constructed. The natural infection experiment was conducted again at different sites, with two replicates used in each site in order to identify the resistance phenotypes of the CSSSLs-2007 and resistant/susceptible controls in 2007. Through the results of 2007, qSTV11 TQ was localized in a region defined by the markers, CAPs1 and Indel4. In order to further confirm the position of qSTV11 TQ , another set of subregion CSSSLs (CSSSLs-2009) was constructed. Finally, qSTV11 TQ was localized to a 55.7?kb region containing nine annotated genes according to the genome sequence of japonica Nipponbare. The relationship between qSTV11 TQ and Stvb-i (Hayano-Saito et al. in Theor Appl Genet 101:59-3, 2000) and the reliability of the markers used on both sides of qSTV11 TQ for marker-assisted breeding of resistance to rice stripe disease are discussed.
