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:Background Rice farming faces a serious challenge from the brown planthopper (BPH), with the pyramiding of BPH14 and BPH15 genes delivering effective protection in elite rice strains. However, the molecular basis behind this resistance is still unclear. Results The study investigated miRNA levels in BPH14/BPH15 pyramiding line (B1415) and their recurrent parent (RP) under BPH infestation employing high-throughput sequencing and revealed 136 differentially expressed miRNAs (DEMs) among 550 known miRNAs. An integrated analysis highlighted that 587 miRNA-mRNA pairs linking 95 DEMs to 537 targeted genes were enriched in phenylpropanoid and lignin metabolism, circadian rhythms, and amino acid metabolism. The candidate DEMs, miR172d-3p, and miR396 family members were identified as negative regulators to decrease their target genes Os06g0708700 (encoding a nodulin-like protein) and Os11g0129700 (encoding an AP2 domain transcription factor), suggesting their key roles in rice against BPH. Conclusions Our investigation provides the first insights into miRNA-mediated defense mechanisms in the B1415. Identifying miRNAs and their target mRNAs in BPH resistance opens a new avenue for rice breeding programs, offering potential targets for improving pest resistance. Understanding these molecular interactions paves the way for developing more resistant rice cultivars, thereby contributing to sustainable rice production and food security.
