Project description:ONAC127 and ONAC129 are NAC transcription factors that involved in abiotic stress response and play key regulatory roles in apoplasmic transportation during rice caryopsis filling. To reveal the transcription regulatory network of ONAC127 and ONAC129 in rice caryopsis, we performed genome-wide identification of ONAC127 and ONAC129 targets by immunoprecipitation sequencing (ChIP-seq) analyses in the overexpression lines of ONAC127 and ONAC129 under natural heat stress(H) and normal cultivation condition(N) with three technical replicates.
Project description:ONAC127 and ONAC129 are NAC transcription factors that involved in abiotic stress response and play key regulatory roles in apoplasmic transportation during rice caryopsis filling. To reveal the transcription regulatory network of ONAC127 and ONAC129 in rice caryopsis, we identified significantly differentially expressed genes by RNA-Seq analysis using the caryopses of the CRISPR-mutants(CR) and overexpression lines(OX) of ONAC127 and ONAC129 under natural heat stress(H) and normal cultivation condition(N).
Project description:We report the application of methylacytosine immunoprecipetation combined with Illumina sequencing (MeDIP-seq) for high-throughput profiling of DNA methylation in rice embryo 3, 6, 9 DAP and endosperm 2, 3, 6, 9 DAP. A total number of 12-14 million of 2×49 bp paired-end reads was generated for each sample, and BOWTIE2 was used for read mapping. We generated genome-wide DNA methylation profiles of rice embryo and endosperm. This study provides a framework to systemically characterize the effect of DNA methylation in developing seeds and will help to illustrate the epigenetic regulation of rice seed development. Rice embryo and endosperm were selected for DNA extraction and methylacytosine immunoprecipetation combined with Illumina sequencing. We sought to obtain the genome-wide DNA methylation profilings of embryo at 3,6,9 days after pollination(DAP) and endosperm at 2,3,6,9 DAP. To that end, we hand-selected embryo at 3,6,9 DAP and endosperm at 2,3,6,9 DAP according to morphological criteria.
Project description:The analysis of gene expression during wheat development:; Gene expression measurements were carried out on a developmental tissue; series for wild-type wheat (cv. Chinese Spring) using the Affymetrix; Wheat GeneChip. Thirteen tissues at defined developmental stages were; chosen to match the barley (cv. Morex) tissue series of Druka et al. 2006 that used the Affymetrix Barley1 GeneChip. Three replicates of:; root tissue at two different developmental stages, leaf, crown,; caryopsis, anther, pistil, inflorescence, bracts, mesocotyl, endosperm,; embryo and coleoptiles were hybridised. Comparisons between this wheat; data and the barley dataset were performed and are available at; http://contigcomp.acpfg.com.au ; [PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Tim Sutton. The equivalent experiment is TA3 at PLEXdb.] Experiment Overall Design: tissue type: germinating seed, coleoptile(3-replications); tissue type: germinating seed, root(3-replications); tissue type: germinating seed, embryo(3-replications); tissue type: seedling, root(3-replications); tissue type: seedling, crown(3-replications); tissue type: seedling, leaf(3-replications); tissue type: immature inflorescence(3-replications); tissue type: floral bracts, before anthesis(3-replications); tissue type: pistil, before anthesis(3-replications); tissue type: anthers, before anthesis(3-replications); tissue type: 3-5 DAP caryopsis(3-replications); tissue type: 22 DAP embryo(3-replications); tissue type: 22 DAP endosperm(3-replications)
Project description:To reveal the underlying molecular mechanism of Gif1 action in the control of grain filling and yield improvement, we performed transcriptional profiling of wild type Zhonghua11 and mutant gif1 plants in early filling stage on a global scale using the Affymetrix GeneChip Rice Genome Array Experiment Overall Design: Rice caryopsis were harvested in 7 days after flowering and three biological repeats were performed on Zhonghua11 (wild-type) and gif1 (mutant), respectively.

Project description:We used microarrays to detail the global programme of gene expression underlying cellularization and identified distinct classes of regulated genes during this process. Rice endosperm at 2 days after pollination(DAP) was selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the endosperm expression profile at 2 DAP. To that end, we hand-selected endosperm according to morphological criteria at 2 DAP before cellularization.
Project description:TMT labeling proteomic analysis was performed on black rice caryopsis after editing an important anthocyanin transporter gene called OsGSTU34
Project description:A ChIP-seq analysis revealed 378 targets of OsMADS29, which include genes involved in cytokinin metabolism and auxin signaling, carbohydrate metabolism, transporters and a large number of transcription factors, reflecting on its functional diversity. Chromatin Immunonoprecipitation of MADS29 using antiMADS29 antibody was done using rice 9 DAP seed tissue with total input chromatin and mock immunoprecipitated chromatin as controls
