The brown planthopper is a sucking insect that, under heavy infestations, can cause the wilting and complete drying of rice plants, a condition known as ‘hopperburn’ (Bottrell and Schoenly, 2012). is a pest of rice in Asia; damage is caused by direct feeding and by the transmission of rice ragged stunt and rice grassy stunt diseases. BPH abbreviation stands for Brown Planthopper. Breeding of resistant cultivars is the most cost-effective and environment-friendly strategy for BPH management; however, resistant cultivars are currently hampered by the rapid breakdown of BPH … The newly developed cultivars having the Sub1 QTL have more than 97% of the genome from the recurrent varieties (Swarna, Sambha Mahsuri, BR11), except for the Sub1 region on chromosome 9, and provide enhanced submergence tolerance for up to 14 days to these varieties (Septiningsih et al., 2009). Among the most important are the, Target Receptors in the Control of Insect Pests: Part I, Karunker et al., 2009; Puinean et al., 2010, Insect Biochemistry and Molecular Biology, Number of the larvae bored into the rice stems. Revealing different systems responses to brown planthopper infestation for pest susceptible and resistant rice plants with the combined metabonomic and gene-expression analysis. Gupta, M.K. For example, a Neotropical treehopper species (Aconophora compressa) has been introduced into Australia for control of Lantana (Verbenaceae). A good example of the problem of QTL × environment can be found from the work published on the rice population CT9993/IR62266, phenotyped for grain yield under drought stress in a wide range of environments. Furthermore, reducing the use of early-season insecticides, which destroy natural enemy complexes that help regulate brown planthopper populations, is probably critical for the long-term use of resistant varieties (Cohen et al., 1997). In rice, progress has been made with the introgression of major genes for improving tolerance of bacterial leaf blight, brown spot, Although the vast majority of species of Auchenorrhyncha are benign, the group contains some of the most destructive pests of agriculture. Nutrient-use efficiency: Molecular approaches should be used as a priority for the identification of genes for efficient nutrient uptake and transport. Genome-wide transcriptome profile of rice hybrids with and without Oryza rufipogon introgression reveals candidate genes for yield. The large jaws of the stem borer gnawing rice with a high Si content would wear out more easily than that gnawing rice with a low Si content. What does BPH stand for? This site needs JavaScript to work properly. Desaturases are essentially required for unsaturated fatty acid (UFA) biosynthesis. In rice, a single gene, Bph-1, conferred resistance to brown planthopper in a variety IR 26 but this broke down within 2 years. The brown planthopper (BPH) is a rice-specific herbi-vore, which causes severe yield losses each year in rice planting areas throughout Asia (Cheng et al. 1991). In the past, a number of genetic studies on disease- and insect-pest-resistant varieties were conducted. What is the abbreviation for Brown Planthopper? Three brown longitudinal convex ridges can usually be observed on the back of adults. It is alarming that a sharp increase in the … In this study, HPLC, MS/MS, and NMR techniques were used to identify active compounds in total flavonoids of rice. Background The brown planthopper (BPH) Nilaparvata lugens (Stål) is one of the most serious insect pests of rice in Asia. The brown planthopper (BPH), Nilnparrara Iugeris (Stal.) The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is a planthopper species that feeds on rice plants (Oryza sativa L.). The brown planthopper (Nilaparvata lugens Stål; BPH) has become a severe constraint on rice production. Our results revealed that Nl Gr7 has an active association with various ligands, such as lectins, lipids (phospho- and sphingolipid) and copper. What are the genes for phenotypic plasticity and are they conserved? The recently identified major QTLs for grain yield under drought in the background of the improved mega varieties (Venuprasad et al., 2009) have potential for improving the drought resistance of cultivar Swarna through introgression of the identified region after fine mapping. Interestingly, much if not most of the economic damage done by spittlebugs is due to native spittlebug species colonizing nonnative hosts (e.g., introduced forage grasses, and clovers). Briggs and Knowles (1967) mentioned that resistance studies usually require the following: Pure lines of the host to serve as resistant and susceptible parents of crosses, A uniform and ideal environment of the pathogen or insect, such that resistance and susceptibility are clearly differentiated, A suitable method of inoculation or infestation so that the disease or insect has an equal opportunity for development on all materials of the study, A consistent system of classification preferably similar to that used by others conducting similar studies, Provision to grow self progenies of a cross through F3 since F3 families give the best measure of the F2 genotype. A number of genes have been identified as resistant against different insect-pests but resistance broke down within a short timespan. Gallun and Khush (1980) reported the effectiveness of a major gene for resistance to jassids in cotton. Please enable it to take advantage of the complete set of features! Background: Brown planthopper (BPH) is the most destructive insect in rice production. Cicadas are used as food by several human cultures. Brown planthopper (BPH) is the most devastating pest of rice. It is alarming that a sharp increase in the frequency and extent of hopper outbreaks has been noticed since ~2002, resulting in gross losses of rice crop, particularly in China, Thailand, and Vietnam (Fujita et al., 2013). The brown planthopper(BPH), Nilaparvata lugens, is the most destructive insect pest in rice production worldwide. Although the insect is endemic in the tropics where On one hand, OsSLR1 … Recently, Sub1, a major QTL for submergence tolerance (Xu et al., 2006), was introgressed into Swarna, Sambha Mahsuri, and BR11 mega varieties. Practically, an understanding of these mechanisms is predicted to enable more precise and sustainable population control of economically important pests such as aphids and brown planthoppers. (1990) achieved aphid resistance by a diallel mating system in B. juncea. K. Samiayyan, in Integrated Pest Management, 2014. The fungus coils over hyphae and conidia of its host and kills them (Peresse and Le Picard 1980) with a fungistatic sesquiterpene metabolite, deoxyphomenone (Tirilly et al. ), Pierce's disease of grape, citrus variegated chlorosis, and alfalfa dwarf.

High population of planthoppers cause leaves to initially turn orange-yellow before becoming brown and dry and this is a condition called hopperburn that kills the plant. Motohiro Tomizawa, in Advances in Insect Physiology, 2013. Sasamoto (1958, 1960, 1961) investigated the relationship between Si content of rice and behavior of stem borer (Chillo suppressalis Walker). Neither H1 nor H2 imparts resistance to Hessian fly in the Corn belt and a third gene H3 was identified from the variety W38 which imparts resistance to Corn belt type (Caldwell et al., 1946). ( A ) qRT-PCR analysis…, Lignin accumulation is associated with BPH resistance in rice. pests, the brown planthopper (BPH) has been regarded as one of the main rice production constraints in Asia [3–6]. 2013). The brown planthopper (BPH), Nilaparvata lugens Stål, is a major rice pest in many parts of Asia. Silicon suppresses insect pests such as the stem borer, brown planthopper, rice green leafhopper, and whitebacked planthopper, and non-insect pests such as leaf spider and mites. Since several genes/QTLs have been cloned for yield component traits, priority should be given to the pyramiding of yield component QTLs for enhancing yield potential in inbreds, as well as in hybrids. After the discovery of the Mendel laws, systematic work on breeding of disease- and insect-pest-resistant varieties started. Phloem-limited viral and mycoplasmalike pathogens typically multiply within the vector and enter the plant when the insect injects saliva during feeding. Over 150 species are known vectors of economically important plant pathogens. Penicillium funiculosum can smother various fungi in culture and thus prevent pineapple fruit diseases (Lim and Rohrbach 1980). Such studies are not often done, presumably because of their costs and methodological difficulties (Vollrath et al., 1990; Volkmar et al., 1998, 2002, 2004). The variety ‘Mudgo’, for example, showed near-complete immunity to the brown planthopper, with 100% nymphal mortality after 10 days (Pathak, 1969). Identification of heterotic patterns: Genome-based selection is emphasized for the identification of heterotic patterns and to enhance heterosis. JA and SA mediated signaling pathways have been extensively identified in plant stress response against pathogen and insect (Berens et al. RNAi and genome editing: These two newly emerging technologies hold promise and should be explored to enhance pest resistance and improve the quality characteristics of rice cultivars. A conidial suspension of this fungus with carboxymethyl cellulose sprayed on P. personata prevented secondary spread of the pathogen under moist conditions (Mitchell et al. bph の定義が複数ある場合がありますので、bph のすべての意味については辞書で 1 つずつチェックしてください。 英語で定義:Brown Planthopper BPHの他の意味 It is a rice-specific herbivore that ingests assimilates from the phloem leading to stunted … What does BPH stand for? BPH can also transmit Rice Ragged … imidacloprid) is the chief way to control BPH… The increased importance of the brown planthopper as a pest prompted efforts to identify sources of planthopper resistance. Brown planthopper (BPH, Nilaparvata lugens Stål) is a major insect pest of rice plants in Asian countries. Brown planthopper (BPH) causes the most serious damage of the rice crop globally among all rice pests. brown planthopper; lignin; phenylalanine ammonia-lyase; rice; salicylic acid. These include eight First Desaturase family genes, one cytochrome b5 fused desaturase gene (Nlug-Cytb5r) and one Sphingolipid Desaturase gene (Nlug-ifc). Anamorphic Ascomycota also host necrotrophic parasites. R. Serraj, ... R.J. Hijmans, in Advances in Agronomy, 2009. A few examples have been cited to illustrate the above mechanism. Evolving ideas about genetics underlying insect virulence to plant resistance in rice-brown planthopper interactions. The brown planthopper (BPH), Nilaparvata lugens Stål, is one of the major pests of rice. This study investigates the proteomics of BPH interactions with three rice cultivars: the first resistant (PR) to BPH… The brown planthopper also damages rice by transmitting ragged stunt virus and grassy stunt virus. The first brown planthopper-resistant rice variety, ‘IR26’, which contained the resistance gene bph-1, was released by the IRRI in 1973 and was widely adopted by growers throughout Asia. The brown planthopper (BPH) is one of the most destructive insect pests of rice in Thailand. Further screening efforts identified other rice lines with other genes for resistance to the brown planthopper (Khush, 1989). The brown planthopper (BPH), Nilaparvata lugens (Stål), one of the most devastating insect pests of rice (Oryza sativa L.), occurs widely in South, Southeast, and East Asia, as well as in the South Pacific islands and Australia. Disease resistance is known to have been inherited as a monogenic trait following the laws of classical Mendelian genetics. With the availability of high-throughput genotyping platforms, MAS should become an integral part of breeding programs. GM technology: GM technology holds immense potential in rice improvement. IPM also endeavours to use chemicals that act selectively against pests but not against their enemies. 1986, 1987). The amino acid asparagine is a feeding stimulant for the brown planthopper, and levels of sulphur-containing amino acids influence planthopper performance (Horgan, 2009). The brown planthopper (BPH) (Nilaparvata lugens Stål, Hemiptera, Delphacidae) is one of the most destructive insect pests of rice (Oryza sativa L.) throughout the rice-growing countries. Angadi et al. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error, Lignin accumulation is associated with BPH resistance in rice. Then the dominant genes controlling resistance were also found. Currently, the insect pest has been described as the most damaging rice pest in Asia [5–8]. 1981), which produces a diffusible toxin and induces vesicular deformations in its host. The Department of Agricultural Extension revealed that during this hot and dry season Rice growers in the central and northern regions observed the period of BPH (Brown planthopper… Brown planthopper (BPH) outbreak in Thanjavur District, Tamil Nadu. Hawksworth (1981a) gives a long list of additional mycoparasites growing on conidial fungi. The brown planthopper, Nilaparvata lugens, (BPH), which is raging throughout rice growing areas of Asia, is a stubborn rice in­ sect of primary importance also in the south­ ern half of Japan. 2012 Dec 10;13:687. doi: 10.1186/1471-2164-13-687. By continuing you agree to the use of cookies. The brown planthopper resistance gene Bph-14 was recently cloned and found to encode a protein with a leucine-rich repeat (LRR) domain similar to those encoded by some pathogen resistance genes (Du et al., 2009).  |  We examined ways in which the Brown planthopper induced008a (Bphi008a; AY256682) gene of rice (Oryza sativa) enhances the plant's resistance to a specialist herbivore, the brown planthopper (BPH; … Here we studied this for the brown planthopper (BPH) Nilaparvata lugens (Stål). We identified 10 genes encoding putative desaturases in the transcriptome database of the brown planthopper (BPH), Nilaparvata lugens. The brown planthopper (BPH) is an insect pest of rice in Terai. Grow only two rice crops per year and use early-maturing varieties to reduce their continuous breeding. Azucena root-related QTLs have also been introduced into the indica variety Kalinga III, but only one of the five target QTLs had an effect on root length and none had a consistent effect on grain yield under water-limited conditions (Steele et al., 2006). The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae), is a serious pest of rice in China that causes severe damage to rice directly by feeding and indirectly by acting as a vector for rice viruses (Liao et al. What is the abbreviation for Brown Planthopper? The brown planthopper (BPH), Nilaparvata lugens Stål, is one of the major pests of rice. Introduction: Brown planthopper (BPH) is a phloem feeding insect that causes annual disease outbreaks, called hopper burn in many countries throughout Asia, resulting in severe damage to rice production. Identification and pyramiding BPH-resistance genes is an economical and effective solution to increase the resistance level of rice varieties. 3. Gener- These responses result in an antibiosis-type resistance that dramatically reduces the feeding, survival, and population growth of planthoppers (Du et al., 2009). • However, the brown planthopper (BPH, Nilaparvata lugens Stål), which sucks the phloem sap of the rice leaf sheath and transmits viral diseases such as rice grassy stunt virus (RGSV), rice ragged stunt virus (RRSV) and rice wilted stunt virus (RWSV), often leads to severe yield losses in the agricultural industry (Fujita et al. Understanding resistance mechanisms is a critical step toward effective control of BPH. The Brown Planthopper (BPH) Nilaparvata lugens (Stål) has become a number one threat to tropical rice production in many parts of Asia in the last three decades (Dale, 1994). Host plant resistance is an effective, economic and environmentally friendly approach to control crop pests. Background: Among various pests, the brown planthopper (BPH) that damages rice is the major destructive pests. Thus, to show that a pesticide is relatively harmless, or indeed has no measurable effect at all, behavioural studies on the effects of sublethal dosages are necessary. It uses its stylet to penetrate rice phloem, feeding on rice sap and causing direct damage to rice or even plant death. ( A ) Histochemical…, OsMYB30 binds to the AC-like elements in the promoters of OsPAL6 and OsPAL8…, NLM The ensuing decades saw the release of numerous other brown planthopper-resistant lines with other genes for resistance and the development of additional planthopper biotypes (Alam and Cohen, 1998; Bottrell and Schoenly, 2012). Introduction. Leafhoppers and planthoppers are among the most significant groups of vectors of plant pathogens, transmitting viruses, bacteria, and mycoplasmalike organisms. Abigail M. Hayes, ... Laura Corley Lavine, in Advances in Insect Physiology, 2019. Here, we purified and characterized a gustatory receptor (protein) coding gene, NlGr7, from the brown planthopper (BPH) Nilaparvata lugens, which is an important insect pest of rice. Good progress has been made in trait development for resistance to biotic stresses, such as BB, blast, BPH, and gall midge. 1978). The rice brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae), is one of the most serious pests of rice in Asia. All the BPH-resistance genes identified to date have been from indica rice or wild species. Therefore, identification of resistance genes against different insect-pests is of paramount importance for the development of insect-resistant transgenic plants. Guttikonda H, Thummala SR, Agarwal S, Mangrauthia SK, Ramanan R, Neelamraju S. Sci Rep. 2020 Mar 17;10(1):4873. doi: 10.1038/s41598-020-60922-6. This species is considered to migrate from abroad together with the white-backed planthopper, Sogatella furcif era, Epub 2010 Nov 1. Development of novel control strategies can be facilitated by comparison of BPH feeding behaviour on varieties … Similarly, grain yield and drought resistance of the upland cultivars can be improved using major QTLs for grain yield under upland drought stress (Bernier et al., 2007) using marker-assisted recurrent selection (MARS). We show that the brown planthopper (BPH) has cleverly turned this around by exploiting herbivore-induced plant volatiles (HIPVs) that provide safe havens for its offspring. This simple experiment is one of the most effective ways of showing that predators are important in keeping brown planthopper populations low. Silicon suppresses insect pests such as the stem borer, Breeding for Disease and Insect-Pest Resistance, Spiders – The Generalist Super Predators in Agro-Ecosystems, In exclusion cage experiments, cages were initially cleaned of all arthropods. A considerable effort has been devoted to the mapping of root-related QTLs in rice. The discomycete Bisporella pallescens (synonym Calycella monilifera) fruits densely on the conspicuous black conidial patches of Bispora antennata on tree stumps (Jahn 1968). Be careful of the outbreak of Brown planthopper (BPH) due to drought. Identification of transcription factors potential related to brown planthopper resistance in rice via microarray expression profiling. Brown planthopper in West Bengal, India. However, living organisms are finely tuned systems; a chemical does not have to be lethal to threaten the fitness (physical as well as reproductive) of the animal, with unpredictable results on the structure of the biological community (Culin and Yeargan, 1983; Volkmar and Schützel, 1997; Volkmar and Schier, 2005). Noble and Suneson (1943) reported from the crosses of resistant variety Dawson and two susceptible varieties Poso and Bigclub, that Dawson had the dominant duplicate gene for resistance. Most of the lines carrying the desired introgressions failed to have deeper roots than IR64 (Shen et al., 2001). The brown planthopper (BPH), Nilaparvata lugens Stål, is one of the major pests of rice. International Rice Research Newsletter, 3(1):13. While studying the inheritance in aphid tolerant cultivars, non-waxy mutant RC 1425 and susceptible Prakash cultivars of B. juncea, Yadav et al. The biotrophic Debaryomyces hansenii can control penetration of citrus fruit by Penicillium digitatum (Droby et al. The brown planthopper (BPH) Nilaparvata lugens (Hemiptera: Delphacidae) is one of the most devastating insect pests of rice . Heavy infestation by BPH … These insects are among the most important pests of rice, which is the major staple crop for about half the world's population. Prebreeding and trait development: Prebreeding should be the priority for key agronomic traits. To date, 29 major BPH resistance genes have been identified from indica cultivars and wild rice species, and more than ten genes have been fine mapped to chromosome regions of less than 200 kb. NIH Ultimately this data will help explain how the diverse and successful adaptations and life histories that have evolved and continue to evolve. Introduction. Brown planthop-per is a rice-specific herbivore and sucks the phloem sap of rice plants … What are the constraints to plasticity? 1976; Tsuneda and Skoropad 1978, 1980), which forms coils and appressoria and sometimes penetrates the host hyphae. These protective functions of Si may be attributed to Si deposited on the tissue surface. 2009 Dec 29;106(52):22163-8. doi: 10.1073/pnas.0912139106. Aspergillus luchuensis and a diversity of other fungi are parasitized in India by Fusarium udum (Upadhyay et al. They also reported a 0% to 2% level of resistance with H1 and H2 and 0 to 10% level of resistance with one dominant gene and 83% with no dominant gene. Understanding these mechanisms will lead to a better understanding of life history evolution and the realm of possible phenotypes available. Scientific name Two species of planthopper infest rice. It uses its stylet to penetrate rice phloem, feeding on rice sap and causing direct damage to rice or even plant death. BPH is a small brown insect found mainly on the base of rice plants above the water level. Brown planthopper (BPH) Nilaparvata lugens Stål is a serious insect pest of rice in Asian countries. Milling is affected by several factors, of which chalkiness is important, resulting in heavy grain breakage and poor grain quality. This protein is probably involved in the direct or indirect recognition of attack by planthoppers, leading to the activation of a salicylic acid-dependent pathway and resistance-related biochemical responses such as increased production of trypsin proteinase inhibitors and callose deposition. BPH mainly sucks rice phloem sap and transmits plant viruses, i.e., the rice … There is a need to develop NILs for each of these traits, map them, and make them available to breeders for stacking through MAS. Introduction. There are adults with either long or short wings (see below, left). This yeast also acts similarly against Rhizopus stolonifer, Botrytis cinerea, and Alternaria alternata on tomatoes and grapes. The use of Auchenorrhyncha in biocontrol of weeds has also begun to be explored. A number of condial Ascomycota are hosts to biotrophic parasites. The QTL regions were very long and the desirable genes may have been lost due to recombination during backcrossing. When the stem was extracted with water, the number of larvae that moved to the extract from the stem was smaller in the stem containing a higher Si. To exploit potential target genes for applications in transgenic rice to control this sap‐sucking insect … See this image and copyright information in PMC. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Though at present some policy and regulatory constraints exist for the commercialization of GM rice, this should not impede research on and investment in transgenics.  |  However, there are few reports of the introgression of major QTLs in rice. The insect can complete as many as 12 generations in a single year in tropical areas, where it resides year-round, and fewer generations in temperate areas, where it is a migratory pest. Liu C, Hao F, Hu J, Zhang W, Wan L, Zhu L, Tang H, He G. J Proteome Res. Some xylem-limited bacterial pathogens (e.g., Xylella) are apparently unable to travel from the gut to the salivary glands and require regurgitation from the foregut during vector feeding to infect the plant. Till to date, 38 BPH resistance loci have been mapped from cultivated and wild species of rice. The brown planthopper (BPH) Nilaparvata lugens(Stål) is one of the most serious insect pests of rice in Asia. 2020 Aug 5;10(8):2653-2660. doi: 10.1534/g3.120.401372.
