Project description:In rice (Oryza sativa L.), the number of panicles, spikelets per panicle and grain weight are important components of grain yield. These characteristics are controlled by quantitative trait loci (QTLs) and are derived from variation inherent in crops.The identification of different yield related QTLs facilitates an understanding of the mechanisms involved in cereal crop yield, and may have utility in improving grain yield in cereal crops. an understanding of the mechanisms involved in cereal crop yield, and may have utility in improving grain yield in cereal crops. In the present study, We cloned and characterized a large-panicle QTL, and confirmed that the newly identified gene OsEBS (enhancing biomass and spikelet number) increased plant height, leaf size and spikelet number per panicle, leading to an average of 37.62% increase in total grain yield per plant. trait loci (QTLs) and are derived from variation inherent in crops.

Project description:Find the possible signaling pathways which contribute to the cell growth inhibition effect of SW-treated AGS cells Global gene expression profiling is an ideal technique to obtain useful clues for exploration of the anticancer mechanism of SW. Through comparing microarray results between solvent- and SW-treated cells, differentially expressed genes were obtained (>1.5 fold). The microarray results were validated using real-time RT-PCR. We used the KEGG database, STRING database and GO database for further ananlysis, and therefore got the possible signaling pathways underlying the anticancer effect of SW. We analyzed total RNA samples of solvent- and SW-treated AGS cells using the Affymetrix Human Gene 1.0 ST platform. No techinical replicates were performed.

Project description:To understand the molecular mechanism of drought stress resistance mediated by OsABA8ox3 gene, we checked the genome-wide expression profile changes in the OsABA8ox3 RNAi and WT seedlings using the Affymetrix GeneChip under the normal condition and drought stress. A total of 1436 genes showed greater than 2-fold higher expression levels in both WT and RNAi-9 seedlings after drought stress, and most of them had higher up-regulated folds in RNAi-9 seedlings than that of WT. Gene expressions in the OsABA8ox3 RNAi and WT seedlings under the normal and drought stress conditions.
Project description:Alkaline hemicellulytic bacteria Bacillus sp. N16-5 has abroad substrate spectrum and exhibits great growth ability on complex carbohydrates. In order to get insight into its carbohydrate utilization mechanism, global transcriptional profiles were separately determined for growth on glucose, fructose, mannose, galactose, arabinose, xylose, galactomannan, xylan, pectin and carboxymethyl cellulose by using one-color microarrays. Substrate induced gene expression was measured when culture was grown on glucose, fructose, mannose, galactose, arabinose, xylose, galactomannan, xylan and CMC to mid-logarithmic phase.
Project description:HBV mRNAs harboring miR-122 response elements were found to bind and sequester endogenous miR-122. This microarray experiment was carried out to find out differentially expressed genes in Huh7 cells expressing HBV mRNAs. RNA was extracted from Huh7 cells transfected with pcDNA3.1 plasmid containing HBV mRNA with wild type (WT) or mutant (Mut) miR-122 response elements in its 3M-bM-^@M-^Y-UTR or the empty pcDNA3.1 vector (3.1) as a mock. Total RNA was then extracted and processed on Affymetrix microarrays in biological duplicate.
