Project description:The aim of this study was to analyze potential brown planthopper (BPH) resistant genes in Rathu Heenati (RHT) by Affymetrix whole rice genome array,BPH susceptible and resistant rice varieties of TN1（Taichung Native 1）as control. All the resistant related genes derived from RHT will be analyzed according to the SSR markers interval flanked on the chromosome 3, 4, 6 and 10. It will be benefit to the gene clone and marker assistant breeding for Bph3 gene in the near future. We used microarrays to detail the global differential gene expression before and after brown planthopper attack in two different varieties, and identified distinct classes of high enriched genes induced by BPH or constituent in RHT

Stems of the rice plant infected by BPH were collected at 0h (T0), 8h (T8), 24h (T24) after BPH attack, total RNA were extracted for the microarray hybirdlization.

Project description:Nilaparvata lugens, the brown planthopper (BPH) sucks the rice phloem sap containing high sucrose to obtain carbon source. The comparative gene expression analyses were perfomed during feeding against starvation in order to determine sugar transporter and other feeding related gene expression.

Project description:Nilaparvata lugens, the brown planthopper (BPH) sucks the rice phloem sap containing high sucrose to obtain carbon source. The comparative gene expression analyses were perfomed during feeding against starvation in order to determine sugar transporter and other feeding related gene expression. Young BPH females that feed rice seedlings or feed-deprived (water-supplied) for 24 hours were prepared in triplicate. Gene expression was compared in these two groups: feeding and feed-deprived.

Project description:Plant virus triggers numerous responses in its insect vectors. Using the iTRAQ-based quantitative proteomics analysis. Early responses of the insect vector small brown planthopper (Laodelphax striatellus Fallén, SBPH) after acquiring Rice black-streaked dwarf virus (RBSDV) at 3 days and 5 days post first access to disease plants (padp), respectively, were revealed. A total of 582 differentially abundant proteins (DAPs) in SBPH with a fold change > 1.500 or <0.667 (p-value<0.05) were identified. The proteomic analysis in SBPH at 3 days padp revealed 106 high abundant proteins and 193 low abundant proteins, while 5 days padp revealed 214 high abundant proteins and 182 low abundant proteins. Among them, 51 high abundant proteins and 42 low abundant proteins were consistently differentially abundant at both 3 days and 5 days padp.

Project description: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. 1H 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 < 0.05) between the infested and the control groups of each examined rice variety. Metabolic pathway analysis suggested that BPH infestation could perturb transamination during the early stages of infestation (days 1–3) for all rice varieties. In addition, the IL7 and IL308 varieties responded earlier (day 3) than the KD variety (day 8) by perturbing amino acid metabolism, shikimate and gluconeogenesis pathways. By day 8 of the infestation, the KD cultivar responded by activating the amino acid-mediated-de novo pathway whereas the IL308 variety activated the purine and pyrimidine compound-mediated-salvage pathway for nucleotide biosynthesis. This study has identified, for the first time, several potential metabolic pathways for acclimatization and defense mechanisms against BPH infestation. These findings provide a valuable, first insight into BPH resistance mechanisms in Thai Jasmine rice.

Project description:MicroRNAs (miRNAs) regulate a spectrum of development and defense response processes in plants. The brown planthopper (BPH) is the most devastating insect pest of rice, BPH resistance gene BPH15 has a strong resistance to BPH. In this study, we analyzed six miRNA profiles of BPH15 introgression line (P15) and susceptible recipient line (PC) in 3 time points (0h, 6h and 48h) after BPH attacked, and identified 464 known miRNAs and 183 novel miRNAs. Before BPH feeding we identified 23 miRNAs expressed differently in P15 and PC. Then after BPH feeding, 104 miRNAs were found expressed differently in P15, and 80 miRNAs were found expressed differently in PC. Among them, miR167, miR444d, miR1846e, miR3979-3p, miR531 were found to be involved in BPH stress response. The response to BPH of P15 was much wider and more rapidly than PC. The levels of a subset of miRNAs were confirmed by qRT-PCR. The targets of miRNAs were predicted and validated by gene expression profiling. Additionally, the target genes of 2 differently expressed miRNAs (miR160f-5p and miR167a-5p) were confirmed by detecting YFP fluorescence and western blotting. Our data provide an important basis for evaluating the role of miRNA in the regulation of BPH interactions in rice.

Project description:Brown planthopper (BPH) is one of the most destructive pests in rice production. The pyramiding application of BPH-resistance genes BPH14 and BPH15 can effectively improve rice resistance to BPH, however, the molecular mechanisms underlying BPH14/BPH15 pyramiding lines are poorly understood. Here, a mRNA expression profiling analysis was performed on the near isogenic lines (NILs) containing the BPH14, BPH15 or BPH14/BPH15 and their recurrent parent (RP) Wushansimiao. A total of 14492 differentially expressed mRNAs (DEGs) were identified from 12 mRNA profiles of resistant NILs and RP at different feeding stages. In the transcriptome analysis, 531 DEGs appeared to be common among the resistant NILs compared to RP before and after BPH feeding, which were enriched in defense response, phosphorylation and salt stress response. In addition, 258 DEGs shared only in resistant NILs were obtained among the different feeding stages, which were enriched in oxidative stress response, karrikin response and chloroplast organization. 21 DEGs were further selected as candidates for BPH resistance. OsPOX8.1, a potential candidate DEG related to BPH resistance, increased reactive oxygen species levels in rice protoplast. Our results provide valuable information to further explore the defense mechanism of insect-resistant gene pyramiding lines and develop robust strategies for insect control.
