Genetic mapping of the rice resistance-breaking gene of the brown planthopper Nilaparvata lugens

Abstract: Host plant resistance has been widely used for controlling the major rice pest brown planthopper (BPH, Nilaparvata lugens). However, adaptation of the wild BPH population to resistance limits the effective use of resistant rice varieties. Quantitative trait locus (QTL) analysis was conducted to identify resistance-breaking genes against the anti-feeding mechanism mediated by the rice resistance gene Bph1. QTL analysis in iso-female BPH lines with single-nucleotide polymorphism (SNP) markers detected a single r… Show more

“…Similarly, combining genes introgressed from wild rice species together with those from traditional varieties might improve durability; however, resistance genes from wild rice have been shown to be ineffective against certain planthopper populations, despite never having been deployed in farmers' fields. These recommendations assume that virulence to major genes is determined by gene-for-gene mechanisms [48,49]. However, if planthoppers adapt to defense mechanisms (irrespective of underlying genetics) then pyramiding arbitrary gene combinations might play little role in determining durability.…”

“…A prominent paradigm underlying modern resistance breeding is that genes bestow resistance against herbivores in a gene-for-gene mechanism [48,49]. This paradigm has gained some recent support through the identification of a 'virulence gene' associated with planthopper adaptation to Bph1 [49].…”

“…For evaluating the BPH resistance of rice varieties and lines at the vegetative and heading stages, three phenotypic experiments were conducted including the standard seedbox screening test (SSST) [16], modified mass adult plant screening test (MAST) [11], and honeydew excretion test (HET) [17] [18].…”

“…Numerous DNA markers were developed [9] [10] that made it possible to identify and map some genes in the BPH through linkage to existing DNA markers [10] [11]. In the present study, bulked segregant analysis (BSA) [12] with SSR markers was used to detect and locate the chromosomal location of the red gene controlling the red eye mutation in the BPH.…”
