Quantitative 1H NMR metabolome profiling of Thai Jasmine rice (Oryza sativa) reveals primary metabolic response during brown planthopper infestation

Brown planthopper (BPH; Nilaparvata lugens ) is a phloem feeding insect which is one of the most serious threats to rice crops in many countries throughout Asia. 1 H NMR spectroscopy, combined with chemometrics, was used to analyze the polar metabolome from leaf extracts of Thai Jasmine rice (brown...

Description
Summary:Brown planthopper (BPH; Nilaparvata lugens ) is a phloem feeding insect which is one of the most serious threats to rice crops in many countries throughout Asia. 1 H NMR spectroscopy, combined with chemometrics, was used to analyze the polar metabolome from leaf extracts of Thai Jasmine rice (brown planthopper (BPH)-susceptible KD) and its BPH resistant isogenic lines (BPH-resistant IL7 and BPH-resistant + IL308 varieties) with and without BPH infestation at various time points (days 1, 2, 3, 4 and 8). Physiological changes of the rice isogenic lines were different based on the quantitative trait loci of BPH resistance. Multivariate models were capable of distinguishing between the susceptible and the resistant rice varieties throughout the infestation. The concentration of 10 metabolites were significantly altered ( p
