“…In those studies, progenies in virulent/avirulent hybrids did not show typical segregation ratios for the virulence to resistant rice varieties. It has been suggested that the cause of indefinite segregations in the genetic analyses of BPH virulence is due to the polygenic nature of the physiological traits or the genetic heterogeneity of parental 'biotype' populations [15,16]. Our different conclusion regarding the genetics of BPH virulence from that of previous studies seems to largely depend on the purity of the biological materials and accurate evaluation of virulence.…”

“…Several genetic analyses of BPH 'biotypes' have been conducted, and most of the studies have suggested polygenic control of BPH virulence to rice resistance genes [15][16][17]. The recessive nature of the virulence to Bph1 was also reported [11,16].…”

“…Our purpose was to verify whether BPH virulence can be explained using a polygenic or monogenic theory-i.e. whether a gene-for-gene relationship is established between rice resistance and the corresponding BPH virulence [15]. Finally, to directly identify molecular markers linked to the putative virulence gene vBph1, bulked segregant analysis and next-generation sequencing (NGS) technologies were applied [20,21].…”

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.

“…It has been known for a long time that rice resistance to BPH could be overcome by a new ''biotype'' of BPH, which is a virulent strain of the insect with the ability to survive on and damage the previously resistant varieties (39). Although the precise nature of BPH biotype and rice resistance is not clear, their interaction is analogous to ''gene-for-gene'' interaction of the plant/pathogen systems (39,40). Identification of Bph14 in this study makes it clear that a CC-NB-LRR gene mediates such a specific genefor-gene resistance in rice to BPH.…”

Planthoppers are highly destructive pests in crop production worldwide. Brown planthopper (BPH) causes the most serious damage of the rice crop globally among all rice pests. Growing resistant varieties is the most effective and environment-friendly strategy for protecting the crop from BPH. More than 19 BPHresistance genes have been reported and used to various extents in rice breeding and production. In this study, we cloned Bph14, a gene conferring resistance to BPH at seedling and maturity stages of the rice plant, using a map-base cloning approach. We show that Bph14 encodes a coiled-coil, nucleotide-binding, and leucine-rich repeat (CC-NB-LRR) protein. Sequence comparison indicates that Bph14 carries a unique LRR domain that might function in recognition of the BPH insect invasion and activating the defense response. Bph14 is predominantly expressed in vascular bundles, the site of BPH feeding. Expression of Bph14 activates the salicylic acid signaling pathway and induces callose deposition in phloem cells and trypsin inhibitor production after planthopper infestation, thus reducing the feeding, growth rate, and longevity of the BPH insects. Our work provides insights into the molecular mechanisms of rice defense against insects and facilitates the development of resistant varieties to control this devastating insect.herbivore ͉ insect-resistance gene ͉ CC-NB-LRR protein ͉ antibiosis ͉ salicyclic acid signaling

“…On the other hand, the BPH populations retain polygenic flexibility to modify their biotype compositions to overcome the sucking blockage by Bph1 and bph2 (den Hollander and Pathak 1981;Roderick 1994;Tanaka 1999). Accordingly, IR26 and IR42 showed only temporary vertical (resistance gene and biotype specific) resistance until a BPH population adjusts their biotype makeup so as to feed on those resistant varieties.…”

The brown planthopper (BPH), Nilaparvata lugens (Stål), and whitebacked planthopper (WBPH), Sogatella frucifera (Horváth), are the rice monophagous species, which are inevitably associated with rice agriculture in Asia. In the 1970s, BPH suddenly occurred as the most preeminent insect pest of rice and threaten the green revolution in the tropical Asia. The BPH outbreaks in Southeast Asia were caused by disruption of ecological balance between BPH and natural enemies by insecticides, which were accepted as a technical component to ensure the high-yielding output of high-yielding varieties (HYVs) in the tropical paddy ecosystems. The outbreaks in India are primarily attributed to disruption of coevolutional interactions between BPH and local rice plants in the monsoon-prevailing paddy ecosystems by abrupt replacement of BPH-resistant traditional rice varieties with susceptible exotic HYVs by the high-yielding varieties program. Unsuccessful deployment of BPH-resistant IR varieties was critically reviewed in relation to the standardized seedbox screening test (SSST), which had been exclusively used to breed BPH-resistant IR varieties. Sixteen of 19 IR varieties incorporated with the Bph1 and bph2 genes were easily defeated with emergence of adaptive BPH biotypes so that their sequential releases could not stop BPH outbreaks. Only a few varieties such as IR36 and IR64 were found to have durable field resistance to BPH even after breakdown of their monogenic resistance. Field performance of IR36 and IR64 indicated that they have some other resistance traits that cannot be evaluated by the SSST. Incapability to evaluate field resistance traits commits a risk of insidious erosion of those traits during the process of SSST-dependent breeding. That could be a reason for a tentative resistance in most of the BPH-resistant IR varieties. WBPH outbreaks in Punjab plain, prevalence of WBPH and WBPHvectored new virus disease in China and Vietnam, and ovicidal resistance to WBPH in japonica rice were referred with special reference to the wind-borne massive displacement biology of WBPH in the active monsoon rice areas.K.
