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:The 1 Mb tiling array was used to represent the 10.0 Mb to 11.0 Mb region of japonica rice Chromosome 10. A tile path was designed with 36-mer probes at a step of 5 nt. All 388,994 probes were retained and synthesized into a single array. This array was hybridized to the cDNA target used for the full-genome tiling array as well as targets prepared from non-coding RNA sample I and II. Keywords: noncoding RNA

Project description:Phosphate starvation/sufficient rice seedling, root or shoot Pi-starvation or Pi-sufficient stresses responsible rice genes, including previously unannotated genes were identified by Illumina mRNA-seq technology. 53 million reads from Pi-starvation or Pi-sufficient root or shoot tissues were uniquely mapped to the rice genome, and these included 40574 RAP3 transcripts in root and 39748 RAP3 transcripts in shoot. We compared our mRNA-seq expression data with that from Rice 44K oligomicroarray, and about 95.5% (root) and 95.4% (shoot) transcripts supported by the array were confirmed expression both by the array and by mRNA-seq, Moreover, 11888 (root) and 11098 (shoot) RAP genes which were not supported by array, were evidenced expression with mRNA-seq. Furthermore, we discovered 8590 (root) and 8193 (shoot) previously unannotated transcripts upon Pi-starvation and/or Pi-sufficient.

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.

Project description:Abiotic environmental stresses cause serious economic losses in agriculture. These stresses include temperature extremes, high salinity and drought. To isolate drought-responsive novel coding and noncoding genes, we used the next generation sequencing method from three rice cultivars (wild type nipponbare, nipponbare AP2 transgenic plants, wild type vandana). 36 NGS data of mRNA-seq, small RNA-seq, riboZero-seq were analyzed. For the analyses of these data we constructed a TF-TG (Transcription Factor-Target Gene) network and an ap2 rooted cascading tree. Using these networks and tress we isolated lincRNAs, differentially expressed miRNAs and their targets. We identified several drought stress-related novel/function unknown coding transcripts (transcription factors and functional genes) and non-coding transcripts (small noncoding transcripts such as microRNA and long noncoding transcripts) from these database analyses and have constructed databases of drought stress-related coding and noncoding transcripts Identification of drought-responsive Regulatory Coding and Non-coding Transcripts from rice by deep RNA sequencing
