Molecular Approaches for Disease Resistance in Rice

Rice production needs to be sustained in the coming decades, with changing climatic conditions becoming more conducive to the prevalence of disease outbreaks. Major rice diseases collectively cause enormous economic damage and yield instability. Breeding for disease-resistant rice varieties could be one of the best options to counter these disease outbreaks. Disease-screening protocols and newer technologies are essential for effective phenotyping and would aid in gene discovery and function. Understanding the genetics of disease mechanisms and stacking of broad-spectrum disease-resistance genes could lead to faster development of rice varieties with multiple disease resistance. New molecular breeding approaches are discussed for the development of these varieties. The molecular biology of disease resistance is now better understood and could be well manipulated for improved resilience. Transgenic approaches for disease resistance are discussed. Genome-editing tools for the development of disease-resistant rice varieties are thoroughly discussed. The use of bioinformatics tools to speed up the process and to obtain a better understanding of molecular genetics mechanisms of disease resistance is explained.

Fine mapping of qSB-11 LE , the QTL that confers partial resistance to rice sheath blight

et al. 2013

Sheath blight (SB), caused by Rhizoctonia solani kühn, is one of the most serious global rice diseases. No major resistance genes to SB have been identified so far. All discovered loci are quantitative resistance to rice SB. The qSB-11(LE) resistance quantitative trait locus (QTL) has been previously reported on chromosome 11 of Lemont (LE). In this study, we report the precise location of qSB-11 (LE) . We developed a near isogenic line, NIL-qSB11(TQ), by marker-assisted selection that contains susceptible allele(s) from Teqing (TQ) at the qSB-11 locus in the LE genetic background. NIL-qSB11(TQ) shows higher susceptibility to SB than LE in both field and greenhouse tests, suggesting that this region of LE contains a QTL contributing to SB resistance. In order to eliminate the genetic background effects and increase the accuracy of phenotypic evaluation, a total of 112 chromosome segment substitution lines (CSSLs) with the substituted segment specific to the qSB-11 (LE) region were produced as the fine mapping population. The genetic backgrounds and morphological characteristics of these CSSLs are similar to those of the recurrent parent LE. The donor TQ chromosomal segments in these CSSL lines contiguously overlap to bridge the qSB-11 (LE) region. Through artificial inoculation, all CSSLs were evaluated for resistance to SB in the field in 2005. For the recombinant lines, their phenotypes were evaluated in the field for another 3 years and during the final year were also evaluated in a controlled greenhouse environment, showing a consistent phenotype in SB resistance across years and conditions. After comparing the genotypic profile of each CSSL with its phenotype, we are able to localize qSB-11 (LE) to the region defined by two cleaved-amplified polymorphic sequence markers, Z22-27C and Z23-33C covering 78.871 kb, based on the rice reference genome. Eleven putative genes were annotated within this region and three of them were considered the most likely candidates. The results of this study will greatly facilitate the cloning of the genes responsible for qSB-11 (LE) and marker-assisted breeding to incorporate qSB-11 (LE) into other rice cultivars.
