“…BPH1 is the first identified BPH resistance gene, and the resistance was broken down by the BPH biotype 2. Then, BPH2 was identified to resist BPH biotype 2, but the resistance was overcome by BPH biotypes 3 later (10,11). In this study, we showed that BPH1/9-7 and -9 are alternative allelotypes in this locus that confer resistance to BPH biotypes 1, 2, and 3.…”

Brown planthopper (BPH), Nilaparvata lugens Stål, is one of the most devastating insect pests of rice (Oryza sativa L.). Currently, 30 BPHresistance genes have been genetically defined, most of which are clustered on specific chromosome regions. Here, we describe molecular cloning and characterization of a BPH-resistance gene, BPH9, mapped on the long arm of rice chromosome 12 (12L). BPH9 encodes a rare type of nucleotide-binding and leucine-rich repeat (NLR)-containing protein that localizes to the endomembrane system and causes a cell death phenotype. BPH9 activates salicylic acidand jasmonic acid-signaling pathways in rice plants and confers both antixenosis and antibiosis to BPH. We further demonstrated that the eight BPH-resistance genes that are clustered on chromosome 12L, including the widely used BPH1, are allelic with each other. To honor the priority in the literature, we thus designated this locus as BPH1/9. These eight genes can be classified into four allelotypes, BPH1/9-1, -2, -7, and -9. These allelotypes confer varying levels of resistance to different biotypes of BPH. The coding region of BPH1/9 shows a high level of diversity in rice germplasm. Homologous fragments of the nucleotide-binding (NB) and leucine-rich repeat (LRR) domains exist, which might have served as a repository for generating allele diversity. Our findings reveal a rice plant strategy for modifying the genetic information to gain the upper hand in the struggle against insect herbivores. Further exploration of natural allelic variation and artificial shuffling within this gene may allow breeding to be tailored to control emerging biotypes of BPH.brown planthopper | plant-insect interaction | CNL protein | allelotype | evolution

“…In fact, the principal defence mechanism of resistance genes is to cause direct or indirect inhibition of feeding behaviour although inhibition of feeding behaviour has multiple effects on BPH, including lower survival, prolonged nymphal periods, lower weight and reduced oviposition [8,23,41,42]. Even if a simple genetic mechanism mediated by a major virulence gene controls the qualitative difference in BPH responses between 'biotypes', this genetic parsimony might have been masked in wild BPH populations by high levels of genetic diversity and/or heterogeneity [7,22,23,43].…”

“…The longer lasting resistance of these genes reflects variation in the adaption ability of BPH populations to resistance genes. Therefore, the breeding and deployment of new resistant rice varieties should be considered in the context of genetic and physiological mechanisms of BPH adaptation to rice resistance [7,14].…”

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

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 region on the 10th linkage group responsible for the virulence. The QTL explained from 57 to 84% of the total phenotypic variation. Bulked segregant analysis with next-generation sequencing in F 2 progenies identified five SNPs genetically linked to the virulence. These analyses showed that virulence to Bph1 was controlled by a single recessive gene. In contrast to previous studies, the genefor-gene relationship between the major resistance gene Bph1 and virulence gene of BPH was confirmed. Identified markers are available for map-based cloning of the major gene controlling BPH virulence to rice resistance.

“…The great majority are moderately resistant and a few highly antibiotic. There are no confirmed reports of insect resistance 'breakdown' given the emergence of new sogata biotypes, in contrast to the appearance of successive biotypes of the brown planthopper Nilaparvata lugens [66] in tropical Asia, presumably caused by the release of monogenic, highly antibiotic resistance.…”

Rice hoja blanca (RHB; white leaf) devastated rice (Oryza sativa) plantings in tropical America for half a century, before scientists could either identify its causal agent or understand the nature of its cyclical epidemics. The association of the planthopper Tagosodes orizicolus with RHB outbreaks, 20 years after its emergence in South America, suggested the existence of a viral pathogen. However, T. orizicolus could also cause severe direct feeding damage (hopperburn) to rice in the absence of hoja blanca, and breeders promptly realized that the genetic basis of resistance to these problems was different. Furthermore, it was observed that the causal agent of RHB could only be transmitted by a relatively low proportion of the individuals in any given population of T. orizicolus and that the pathogen was transovarially transmitted to the progeny of the planthopper vectors, affecting their normal biology. An international rice germplasm screening effort was initiated in the late 1950s to identify sources of resistance against RHB and the direct feeding damage caused by T. orizicolus, making better progress in the development of hopperburn-resistant than for hojablanca-resistant rice lines. In the 1980s, the identification of a novel virus as the causal agent of RHB, and genetic studies on the interaction of this virus with its planthopper vector, confirmed previous studies on the pathogenic nature of the virus to T. orizicolus and helped explain the cyclical nature of RHB epidemics. This disease is best controlled by hybridization of susceptible indica and resistant japonica rice genotypes and the adoption of integrated disease control practices.
