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...
متن کاملMolecular mapping and genetic analysis of a rice brown planthopper (Nilaparvata lugens Stål) resistance gene.
The brown planthopper (BPH), Nilaparvata lugens Stål, is a serious insect pest of rice (Oryza saliva L.). We have determined the chromosomal location of a BPH resistance gene in rice using SSR and RFLP techniques. A rice line 'B14', derived from the wild rice Oryza latifolia, showed high resistance to BPH. For tagging the resistance gene in 'B14X', an F2 population and a recombinant inbred (RI)...
متن کاملIdentification of Qtls for Brown Planthopper (nilaparvata Lugens Stal.) Resistance in Ril Mapping Population of Rice (oryza Sativa L.)
The brown planthopper (Nilaparvata lugens Stal.) is one of the major insect pests of rice (Oryza sativa L.). Exploitation of Host Plant Resistance is a major component to manage this pest. The development of rice varieties that are resistant to the brown planthopper is an important objective in current breeding programmes. This study was undertaken to identify QTLs for BPH resistance from an el...
متن کاملThe Transcription Factor OsWRKY45 Negatively Modulates the Resistance of Rice to the Brown Planthopper Nilaparvata lugens
WRKY transcription factors play a central role not only in plant growth and development but also in plant stress responses. However, the role of WRKY transcription factors in herbivore-induced plant defenses and their underlying mechanisms, especially in rice, remains largely unclear. Here, we cloned a rice WRKY gene OsWRKY45, whose expression was induced by mechanical wounding, by infestation ...
متن کاملUnderstanding rice plant resistance to the Brown Planthopper (Nilaparvata lugens): a proteomic approach.
Engineering and breeding resistant plant varieties are the most effective and environmentally friendly ways to control agricultural pests and improve crop performance. However, the mechanism of plant resistance to pests is poorly understood. Here we used a quantitative mass-spectrometry-based proteomic approach for comparative analysis of expression profiles of proteins in rice leaf sheaths in ...
