Project description:Here, we present OryzaPG-DB, a rice proteome database based on shotgun proteogenomics, which incorporates the genomic features of experimental shotgun proteomics data. This version of the database was created from the results of 27 nanoLC-MS/MS runs on a hybrid ion trap-orbitrap mass spectrometer, which offers high accuracy for analyzing tryptic digests from undifferentiated cultured rice cells. Peptides were identified by searching the product ion spectra against the protein, cDNA, transcript and genome databases from Michigan State University, and were mapped to the rice genome. Approximately 3200 genes were covered by these peptides and 40 of them contained novel genomic features. Users can search, download or navigate the database per chromosome, gene, protein, cDNA or transcript and download the updated annotations in standard GFF3 format, with visualization in PNG format. In addition, the database scheme of OryzaPG was designed to be generic and can be reused to host similar proteogenomic information for other species. OryzaPG is the first proteogenomics-based database of the rice proteome, providing peptide-based expression profiles, together with the corresponding genomic origin, including the annotation of novelty for each peptide.

Project description:Methionine sulfoxide reductases catalyze the reduction of MetSO back to the correct Met residue. Previously, the gene of Capsicum annuum methionine sulfoxide reductase B2 was isolated and CaMSRB2-overexpressing tomato shows enhanced growth, which may trigger increased resistance to the pathogens. To assess the role of this enzyme in rice, we generated transgenic lines under the control of the rice Rab21 (responsive to ABA protein 21) promoter with/without Bar marker gene. Several physiological tests such as MV and Fv/Fm, indicators of an oxidative stress-inducing agent and a potential maximal PSII quantum yield, respectively strongly suggested CaMSRB2 confers drought tolerance to rice. Using 3′-tiling microarray covering the whole rice genes, we carried out genome-wide expression analyses with CaMsrB2-transformed rice (Oryza sativa L. cv. ILMI). Rice was grown in port for six weeks and treated with drought by water withholding for two days.

Project description:Fairy rings are zones of stimulated grass growth by the interaction between the fungi and the plant. In the previous research, we reported the identification of the “fairy”, 2-azahypoxanthine (AHX), produced by the fairy ring-forming fungus and the mechanism of its growth-promoting activity using DNA microarray. We discovered AOH, a common metabolite of AHX in plants. We investigate expression profiling of rice seedlings treated with AHX or AOH for the mechanism of their growth-promoting activity.

Project description:This experiment was designed to identify transcribed regions of japonica subspecies of the rice genome. A series of high-density oligonucleotide tiling arrays that represent sense and antisense strands of the entire nonrepetitive sequence of all the 12 chromosomes were designed to measure genome-wide transcription. A total of 12253842 36mer oligonucleotide probes positioned every 46 nt on average were used for this purpose. The probes were synthesized via maskless photolithography at a feature density of approximately 389,000 probes per slide. The arrays were hybridized with fluorescence-labeled cDNA reverse-transcribed from equal amounts of four selected poly(A)+ RNA population (seedling root, seedling shoot, panicle, and suspension cultured cells). Keywords: tiling array, genome-wide transcription

Project description:In this study, we employed a special size fractionation and cDNA library construction method followed by 454 deep sequencing to systematically profile rice intermediate-size ncRNAs. Our analysis resulted in the identification of 1349 ncRNAs in total, including 754 novel ncRNAs of an unknown functional category. Chromosome distribution of all identified ncRNAs showed no strand bias, and displayed a pattern similar to that observed in protein-coding genes with few chromosome dependencies. More than half of the ncRNAs were centered around the plus-strand of the 5’ and 3’ termini of the coding regions. The majority of the novel ncRNAs were rice specific, while 78% of the small nucleolar RNAs (snoRNAs) were conserved. Tandem duplication drove the expansion of over half of the snoRNA gene families. Furthermore, 90% of the snoRNA candidates were shown to produce small RNAs between 20-30 nt, 80% of which were associated with ARGONAUT proteins generally, and AGO1b in particular. Overall, our findings provide a comprehensive view of an intermediate-size non-coding transcriptome in a monocot species, which will serve as a useful platform for an in-depth analysis of ncRNA functions.
