Project description:<p>Pigmented rice (<em>Oryza sativa L.</em>) is a rich source of nutrients, but pigmented lines typically have long life cycles and limited productivity. Here we generated genome assemblies of 5 pigmented rice varieties and evaluated the genetic variation among 51 pigmented rice varieties by resequencing an additional 46 varieties. Phylogenetic analyses divided the pigmented varieties into four varietal groups: Geng-japonica, Xian-indica, circum-Aus and circum-Basmati. Metabolomics and ionomics profiling revealed that black rice varieties are rich in aromatic secondary metabolites. We established a regeneration and transformation system and used CRISPR-Cas9 to knock out three flowering time repressors (Hd2, Hd4 and Hd5) in the black Indonesian rice Cempo Ireng, resulting in an early maturing variety with shorter stature. Our study thus provides a multi-omics resource for understanding and improving Asian pigmented rice.</p>

Project description:Abstract We have re-analysed publicly available mass spectrometry (MS) data sets enriched for phosphopeptides from Asian rice (Oryza sativa). In total we have identified, 15522 phosphosites on Serine, Threonine and Tyrosine residues on rice proteins. The data has been loaded into UniProtKB, enabling researchers to visualise the sites alongside other stored data on rice proteins, including structural models from AlphaFold2, and into PeptideAtlas, enabling visualisation of the source evidence for each site, including scores and source mass spectra. We identified sequence motifs for phosphosites, and link motifs to enrichment of different biological processes, indicating different downstream regulation caused by different kinase groups. We cross-referenced phosphosites against single amino acid variation (SAAV) data sourced from the rice 3000 genomes data, to identify SAAVs within or proximal to phosphosites that could cause loss of a particular site in a given rice variety. The data was further clustered to identify groups of sites with similar patterns across rice family groups, allowing us to identify sites highly conserved in Japonica, but mostly absent in, for example, Aus type rice varieties - known to have different responses to drought. These resources can assist rice researchers to discover alleles with significantly different functional effects across rice varieties.

Project description:[Oryza sativa Genome Oligo Set Version 1.0 was designed by Beijing Genomics Institute (BGI) and contain 60,727 70mer oligos representing both indica and japonica genomes. All oligos were designed from cDNAs, expreseed sequence tag (EST) sequences, predicted genes of BGI rice genome build and other public resources. Mapping to TIGR rice genome pseudommolecues release 2 is based on the BLAST results, if a oligo has greater than 97% identity to a gene sequence from TIGR pseudomolecules, the oligo represents that gene. Rice 30K Operon Version 1.0 -70 mer oligos. The array is in 48 pin conformation. It has 25 columns and 25 rows in each of 4 x 12 subarrays. This is the slideA of the two slide sets.

Project description:Rice, the world’s most important food crop, is attacked by multiple herbivores and pathogens.the rice striped stem borer (SSB) Chilo suppressalis is one of another most important rice insect pests. Here, we use Affymetrix Whole-Genome rice arrays to detect SSB infestation responsive genes.

Project description:In this study, we provide a global overview of genome-wide OsHOX24 binding sites in rice under control and desiccation stress conditions in wild-type and OsHOx24 overexpressing rice plants (H49 line) via chromatin immunoprecipitation sequencing (ChIP-sequencing) approach. We identified numerous downstream targets of OsHOX24 under desiccation stress and control by analyzing the comprehensive binding site map of OsHOX24 at whole genome level in rice.

Project description:This experiment was designed to identify transcribed regions of indica rice genome. A series of high-density oligonucleotide tiling arrays that represent sense and antisense strands of the entire nonrepetitive sequence of the chromosome were used to measure transcriptional activities. A total of 838,816 36mer oligonucleotide probes, positioned every 46 nt on average, were designed to interrogate the indica genome, respectively. 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 populations, namely, seedling roots, seedling shoots, panicles, and suspension cultured cells of the respective rice subspecies.

Project description:Rice is one of important crop and, the genome has been already completely sequenced. Moreover we collected more than 30K rice FL-cDNA clones as transcriptome resources. However, the cDNA collection did not reveal the transcription activity and specificity of expression. So, we designed 60-mer oligo array based on the array system of Agilent Technologies (GPL477) as custom array. For validation of the array, we tested the reproducibility of labeling and hybridization. After this validation, 22K rice oligo array was supplied from Agilent Technologies (GPL892). 2: reproducibility of hybridization-1: We made a dye-swap experiment to validate dye-effect and data reproducibility between arrays. We hybridized shoot (as control) and other developmental stage tissues. This data also indicated the diversity of gene expression profile among developmental stages. Keywords: variety among tissues

Project description:In angiosperms, stigma provides initial nutrients and guidance cues for pollen grain germination and tube growth. However, little is known about genes that regulate these processes in rice. Here we generate rice stigma-specific gene expression profiles through comparing genome-wide expression patterns of hand dissected unpollinated stigma at anthesis with seven tissues including seedling shoot, seedling root, mature anther, ovary at anthesis, seeds of five days after pollination, 10-day-old embryo, 10-day-old endosperm as well as suspension cultured cells by using 57K Affymetrix rice whole genome array. In total, we identified 665 probe sets (550 genes) to be expressed specifically or predominantly in the stigma papillar cells of rice. Real-Time quantitative RT-PCR analysis of 34 selected genes confirmed their stigma-specific expression. The expression of five selected genes was further validated by RNA in situ hybridization. Gene annotation shows that several auxin-signaling components, transporters and stress-related genes are significantly overrepresented in the rice stigma gene set. We also found that genes involved in cell wall metabolism and cellular communication appear to be conserved in the stigma between rice and Arabidopsis. Our results indicate that the stigmas appear to have conserved and novel molecular functions between rice and Arabidopsis.
