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:5 leaves old rice plantlets were infected with Magnaporthe grisea spores and zero, two hours and twenty four houres after infection samples were collected
Project description:IDS1 is a rice AP2-type transcription factor with transcritpional repression activity. To understand how IDS1 regulate rice salt tolerance, the ChIP-seq experiments were performed to identify IDS1 binding site in globle genomic level. The two-weeks-old rice seedlings were lysated and sonificated and IDS1-DNA complexes were immune precipated with myc-antibody and protein A beads. The purified DNA samples were used to construct sequencing libraries and sequenced with Illumina. The data were then analyzed with bio-informatic tools.
Project description:In this study, we investigated novel rice genes that are expressed in aleurone cells by RNA-seq. RNA-seq was performed on four samples: a control sample, and samples treated with ABA, GA, and a mixture of the two hormones.
Project description:To investigate impacts of genome-wide loss of Cytosine methylation at CG sites (mCs) on global expression of protein-coding genes (henceforth referring to genes), we conducted deep RNA-seq analysis on OsMET1-2â/â relative to its sibling WT and heterozygote (OsMET1-2+/â), each with two biological replicates
Project description:LongSAGE library in this series are from 'Whole Genome Analysis of Pathogen-Host Recognition and Subsequent Responses in the Rice Blast Patho-System' project. This work is supported by NSF-PGRP #0115642. Keywords: other
Project description:Artificial miRNA mediated knock-down ago18 transgenic lines [ago18(1), ago18(2)] showed developmentally compromised phenotype in both vegetative and reproductive tissues compared to wild-type control. We have performed small RNA seq to investigate underlying molecular mechanism and to reveal functional role of AGO18 in rice.
Project description:In this study, we used RNA-Seq to understand the mechanisms of Cd toxicity, cellular detoxification and protection pathways in response to Cd in rice roots. To gain additional insight into the rice transcriptomic response to environmental Cd stress, 15-day-old rice seedlings were treated with 10 or 100 μM solutions of Cd2+, or without Cd (control), for 24 h, at which point root samples were harvested and labeled as Cd+, Cd++, and control, respectively. These samples were used for 101 bp paired-end (PE) deep sequencing on an Illumina HiSeq 2500 platform.
Project description:The R-loop is a common chromatin feature presented from prokaryotic to eukaryotic genomes and has been revealed to be involved in multiple cellular processes and associated with many human diseases. Here, we take the advantage of our recently developed ssDRIP-seq method to profile genome-wide R-loop levels and provided a first-hand R-loop atlas of Rice (Oryza sativa) at different developmental stages.
