Project description:We isolated an efficient tetracycline degrading strain Sphingobacterium sp. WM1. To investigate gene expression patterns during tetracycline degradation by strain WM1, we conducted a comparative transcriptomic analysis using cultures of strain WM1 with and without tetracycline addition. The RNA-Seq data revealed that 90.44-96.56% of the reads mapped to the genome of Sphingobacterium sp. WM1 across all samples. Differentially expressed genes (DEGs) analysis (|log2FC| >2; p < 0.01) showed that 693 genes were significantly up-regulated and 592 genes were significantly down-regulated.

Project description:Grain filling in maize (Zea mays L.) is intricately linked to cell development, involving the regulation of genes responsible for the biosynthesis of storage reserves (starch, proteins, and lipids) and phytohormones. However, the regulatory network coordinating these biological functions remains unclear. In this study, we identified 1,744 high-confidence target genes co-regulated by the transcription factors (TFs) ZmNAC128 and ZmNAC130 (ZmNAC128/130) through chromatin immunoprecipitation sequencing coupled with RNA-seq analysis in the zmnac128/130 loss-of-function mutants. We further constructed a hierarchical regulatory network using DNA affinity purification sequencing analysis of downstream TFs regulated by ZmNAC128/130. In addition to target genes involved in the biosynthesis of starch and zeins, we discovered novel target genes of ZmNAC128/130 involved in the biosynthesis of lipids and indole-3-acetic acid (IAA). Consistently, the number of oil bodies, as well as the contents of triacylglycerol and IAA were significantly reduced in zmnac128/130. The hierarchical regulatory network centered by ZmNAC128/130 revealed a significant overlap between the direct target genes of ZmNAC128/130 and their downstream TFs, particularly in regulating the biosynthesis of storage reserves and IAA. Our results indicated that the biosynthesis of storage reserves and IAA is coordinated by a multi-TFs hierarchical regulatory network in maize endosperm.

Project description:modENCODE_submission_2430 This submission comes from a modENCODE project of Michael Snyder. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We are identifying the DNA binding sites for 300 transcription factors in C. elegans. Each transcription factor gene is tagged with the same GFP fusion protein, permitting validation of the gene's correct spatio-temporal expression pattern in transgenic animals. Chromatin immunoprecipitation on each strain is peformed using an anti-GFP antibody, and any bound DNA is deep-sequenced using Solexa GA2 technology. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-seq. BIOLOGICAL SOURCE: Strain: OP77(made_by : R. Waterston description : This strain's transgene was constructed by Mihail Sarov at the Max Planck Institute for Cell Biology in Tubiginen using Tony Hyman's recombineering pipeline. The resulting plasmid was used for biolistic transformation of an unc-119(ed3) strain. The UNC-130::EGFP fusion protein is expressed in the correct unc-130 spatio-temporal expression pattern. This strain was used for ChIP-seq experiments to map the in vivo binding sites for the UNC-130 transcription factor. tags : GFP::3xFlag mutagen : Bombard outcross : 3 genotype : unc-119(ed3) III; wgIs77 [unc-119(+) unc-130::TY1::EGFP::3xFLAG] official name : OP77 ); Developmental Stage: fed L1; Genotype: unc-119(ed3) III; wgIs77 [unc-119(+) unc-130::TY1::EGFP::3xFLAG]; Sex: Hermaphrodite; EXPERIMENTAL FACTORS: Developmental Stage fed L1; Target gene unc-130; Strain OP77(made_by : R.
