Xu et al (2002) reported seven main-effect QTLs and many epistatic QTLs associated with quantitative resistance to BPH using a recombinant inbred line derived from Teqing × Lemont populations. Su et al (2002) detected QTLs on chromosomes 2, 10, and 12 using a Nipponbare × Kasalath backcross population.…”

“…For example, the Bph11 (bph11), Bph12 (bph12) and Bph13 [Bph13(t)] genes are existing as duplicate genes. A new BPH resistance derived from IR1154-243 was located on chromosome 4 and was named as Bph11 (Xu et al 2002). However, the bph11 gene was identified in an introgression line derived from O. officianalis on chromosome 3 (Hirabayashi and Ogawa 1995).…”

Among the planthoppers of rice, the brown planthopper (BPH) is a major threat to rice production and causes significant yield loss annually. Host-plant resistance is an important strategy to reduce the damage caused by BPH and increase rice productivity. Twenty-one major genes for BPH resistance have been identified by using standard evaluation methods developed at the International Rice Research Institute (IRRI) to distinguish resistance or susceptibility of rice genotypes to BPH biotypes/populations. These genes are from diverse genetic resources such as land race cultivars and wild species of Oryza. Of the 21 resistance genes, 18 genes have been localized on specific region of six rice chromosomes using molecular genetic analysis and genomics tools. Some of these resistance genes are clustered together such as Bph1, bph2, Bph9, Bph10, Bph18, and Bph21 on the long arm of chromosome 12; Bph12, Bph15, Bph17 and Bph20 on the short arm of chromosome 4; bph11 and Bph14 on the long arm of chromosome 3 and Bph13(t) and bph19 on the short arm of chromosome 3. Six genes (Bph11, bph11, Bph12, bph12, Bph13 and Bph13) originated from wild Oryza species have either duplicate chromosome locations or wrong nomenclature. The discrepancy should be confirmed by allelism tests. Besides identification of major resistance genes, some quantitative trait loci (QTLs) associated with BPH resistance have also been identified on eight chromosomes. Most of the rice cultivars developed at IRRI possess one or two of the major resistance genes and the variety IR64 has many QTLs and confers strong resistance to BPH. More BPH resistance genes need to be identified from the wealth of gene pool available in the wild species of Oryza. Two BPH resistance genes (Bph14 and Bph18) have been cloned, and a snow drop lectin gene (GNA) has been identified and used in the development of BPH-resistant transgenic plants. Efficient introgression of resistance genes (Bph1, bph2, Bph3, Bph14, Bph15, Bph18, Bph20, and Bph21) into elite rice cultivars by marker-assisted selection together with strategic deployment of these genes can be an important approach to develop stable resistance to BPH and sustain rice production in the tropical and temperate rice growing regions.

“…Therefore, comparative analyses of genomic locations for disease resistance in rice chromosome 6 with creeping bentgrass LG 7 was also conducted. A QTL for BPHRS (brown planthopper resistance) is located 5 cM away from RZ516 (Xu et al 2002), and a blast resistance QTL is located close to RG213 (Talukder et al 2005), 30 cM away from RZ516. However, QTL for BBRS (bacterial blight disease resistance) and SHBTRS (sheath blight disease resistance) have not been reported on chromosome 6.…”

Dollar spot caused by Sclerotinia homoeocarpa F. T. Bennett is the most economically important turf disease on golf courses in North America. Dollar spot resistance in a creeping bentgrass cultivar would greatly reduce the frequency, costs, and environmental impacts of fungicide application. Little work has been done to understand the genetics of resistance to dollar spot in creeping bentgrass. Therefore, QTL analysis was used to determine the location, number and eVects of genomic regions associated with dollar spot resistance in the Weld. To meet this objective, Weld inoculations using a single isolate were performed over 2 years and multiple locations using progeny of a full sib mapping population '549 £ 372'. Dollar spot resistance seems to be inherited quantitatively and broad sense heritability for resistance was estimated to be 0.88. We have detected one QTL with large eVect on linkage group 7.1 with LOD values ranging from 3.4 to 8.6 and explaining 14-36% of the phenotypic variance. Several smaller eVect QTL speciWc to rating dates, locations and years were also detected. The association of the tightly linked markers with the LG 7.1 QTL based on 106 progeny was further examined by single marker analysis on all 697 progeny. The high signiWcance of the QTL on LG 7.1 at a sample size of 697 (P < 0.0001), along with its consistency across locations, years and ratings dates, indicated that it was stable over environments. Markers tightly linked to the QTL can be utilized for marker-assisted selection in future bentgrass breeding programs.

“…It is of interest that plant resistance genes, including major (qualitative) and minor (quantitative, QTL) genes, tend to be clustered in the particular regions of chromosomes (Beavis et al 1991;Wang et al 1994;Xu et al 2002;Ramalingam et al 2003;Yang et al 2003). Aside from the bph19(t) gene, one major gene Bph13(t) and two QTLs were mapped on the short arm of rice chromosome 3 (Fig.…”

“…One QTL accounted for only 3.8% of the phenotypic variance was identified to a marker interval, RG944-RG348, which is farther than the Bph13(t) locus from the bph19(t) locus ( Fig. 2a; Xu et al 2002). Another QTL predominantly associated with a single resistance mechanism, antixenosis, was also identified to a marker interval, RG191-RZ678, which covers the bph19(t) location ( Fig.…”

Genetic analysis and fine mapping of a rice brown planthopper (Nilaparvata lugens Stål) resistance gene bph19(t)

Genetic analysis and fine mapping of a resistance gene against brown planthopper (BPH) biotype 2 in rice was performed using two F(2) populations derived from two crosses between a resistant indica cultivar (cv.), AS20-1, and two susceptible japonica cvs., Aichi Asahi and Lijiangxintuanheigu. Insect resistance was evaluated using F(1) plants and the two F(2) populations. The results showed that a single recessive gene, tentatively designated as bph19(t), conditioned the resistance in AS20-1. A linkage analysis, mainly employing microsatellite markers, was carried out in the two F(2) populations through bulked segregant analysis and recessive class analysis (RCA), in combination with bioinformatics analysis (BIA). The resistance gene locus bph19(t) was finely mapped to a region of about 1.0 cM on the short arm of chromosome 3, flanked by markers RM6308 and RM3134, where one known marker RM1022, and four new markers, b1, b2, b3 and b4, developed in the present study were co-segregating with the locus. To physically map this locus, the bph19(t)-linked markers were landed on bacterial artificial chromosome or P1 artificial chromosome clones of the reference cv., Nipponbare, released by the International Rice Genome Sequencing Project. Sequence information of these clones was used to construct a physical map of the bph19(t) locus, in silico, by BIA. The bph19(t) locus was physically defined to an interval of about 60 kb. The detailed genetic and physical maps of the bph19(t) locus will facilitate marker-assisted gene pyramiding and cloning.
