Site-specific SUMOylation proteomics in Arabidopsis

ABSTRACT: Identifying SUMOylation target sites in plants poses a significant challenge due to their relatively low abundance and high dynamics. Through this lysine-null SUMO1 method and the optimized two-step purification procedure, we successfully identified over 2,000 SUMOylation sites from 1,300 putative SUMO acceptors, significantly deepening the current SUMOylome in plants. Identification of thousands of SUMOylation sites offers a unique opportunity to comprehend the biological function and site specificity of SUMOylation at the proteome level.

Jpx RNA regulates CTCF anchor site selection and formation of chromosome loops

Project description:Chromosome loops shift dynamically during development, homeostasis, and disease. CTCF is known to anchor loops and construct 3D genomes, but how anchor sites are selected is not yet understood. Here we unveil Jpx RNA as a determinant of anchor selectivity. Jpx RNA targets thousands of genomic sites, preferentially binding promoters of active genes. Depleting Jpx RNA causes ectopic CTCF binding, massive shifts in chromosome looping, and downregulation of >700 Jpx target genes. Without Jpx, thousands of lost loops are replaced by de novo loops anchored by ectopic CTCF sites. Although Jpx controls CTCF binding on a genome-wide basis, it acts selectively at the subset of developmentally sensitive CTCF sites. Specifically, Jpx targets low-affinity CTCF motifs and displaces CTCF protein through competitive inhibition. We conclude that Jpx acts as a CTCF release factor and shapes the 3D genome by regulating anchor site usage.

Saccharomyces cerevisiae 3' poly(A) site mapping

Project description:The use of alternative polyadenylation sites is common and affects the post-transcriptional fate of mRNA, including its stability, localization, and translation. Here we present a method for genome-wide and strand-specific mapping of poly(A) sites and quantification of RNA levels at unprecedented efficiency by using an on-cluster dark T-fill procedure on the Illumina sequencing platform. Our method outperforms former protocols in quality and throughput, and reveals new insights into polyadenylation in Saccharomyces cerevisiae. Experimental benchmark of five different protocols (3tfill, bpmI, internal, rnaseq and yoon) for genome-wide identification of polyadenylation sites in Saccharomyces cerevisiae and transcript quantification. RNA was extracted from WT cells grown in glucose (ypd) or galactose (ypgal) as carbon source. The same RNA was used for 3 independent library constructions (technical replicates, rep).

Optimization of an RNA-centric approach searching for RNA-interacting proteins in Arabidopsis thaliana

Project description:The number of methods used to study RNA-protein interactions in plants is currently relatively limited. The RNA-centric approach, starting with RNA of interest, brings several difficulties, especially when the RNA belongs to the less abundant RNAs. These methods for identification of RNA-interacting proteins used to be developed for different model systems, however, their application in plants is delayed. The Comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP-MS) method was originally developed for mammalian cells. This work describes the modified ChIRP-MS procedure applicable in Arabidopsis thaliana. All steps were optimized for the telomerase RNA which was recently described as a low-abundant RNA. Following this optimization procedure, it is possible to use ChIRP-MS as a screening method for the identification of candidate proteins interacting with the target RNA.

Pioneer activity distinguishes activating from non-activating SOX2 binding sites [ChIP-Seq]

Project description:Genome-wide transcriptional activity involves the binding of many transcription factors to thousands of sites in the genome. Determining which sites are directly driving transcription remains a challenge. Here we use acute protein depletion of the pioneer transcription factor SOX2 to establish its functionality in maintaining chromatin accessibility. We show that thousands of accessible sites are lost within an hour of protein depletion, indicating rapid turnover of these sites in the absence of pioneer factors. To understand the relationship with transcription we performed nascent transcription analysis and found that open chromatin sites that are maintained by SOX2 are highly predictive of gene expression, in contrast to all other SOX2 binding sites. We use CRISPR-Cas9 genome editing in the Klf2 locus to functionally validate a predicted regulatory element. We conclude that the regulatory activity of SOX2 is exerted largely at sites where it maintains accessibility and that other binding sites are largely dispensable for gene regulation.

Identificatioin of phosphoarginine proteins and sites in Jurkat cells by LC-MS/MS

Project description:Acid and heat lability greatly hindered the study of N-phosphorylation (pArg, pHis and pLys), and limited progresses were focus on prokaryotes since the O-phosphorylation is of high abundance in eukaryotes. To meet the challenge, this paper mainly described the identification of phosphoarginine (pArg) proteins and sites in human Jurkat cells by LC-MS/MS under an optimized proteomic experimental procedure. The optimization included cell stimulation conditions, protein extraction methods and MS/MS fragmentation modes. Under this best procedure， hundreds of pArg proteins and sites were unambiguously identified in Jurkat cells from two biological replicates. GO analysis revealed that the pArg proteins may play an important role in nucleic acid-related functions. Besides, this resource also contains the identification information of pHis and pLys.

Gene Editing of Gibberellin-Oxidase20 improves plant architecture and drought tolerance in maize

Project description:As a major plant abiotic stress, drought stress suppresses crop yield performance severely. However, the trade-off between crop drought tolerance and yield performance becomes a great challenge in drought-resistant crop breeding. Several phytohormones have been reported to participate in plant drought response, including gibberellin (GA), which also plays an important role in plant growth and development. Using CRISPR technology, we constructed the null mutant of ZmGA20ox3, a key enzyme in GA biosynthesis. The null mutant plants show lower plant height and ear height with no yield loss under the normal condition than wild-type plants. Transcriptome analysis revealed that genes affected by ZmGA20ox3 were enriched in signal transduction and stress response processes. In addition to the decrease of GA, a significant increase of ABA and JA level were also detected in mutant plants. Compared with wild-type plants, the growth and ASI of mutant plants were less affected, and the yield loss was also reduced under drought conditions. These results suggest a potential role of ZmGA20ox3 in maize drought response. Our result shows that regulating GA biosynthesis is applicable for maize drought-resistant breeding.

Regulatory Modules Controlling Maize Inflorescence Architecture: ChIP-seq data

Project description:In this study we investigated the developmental dynamics of genes targeted in vivo by the transcription factor RAMOSA1, a key regulator of determinacy, and revealed potential mechanisms for repressing branches in distinct stem cell populations in developing maize inflorescences. To identify targets of RA1 and to distinguish direct vs. indirect interactions, we performed Chromatin Immunoprecipitation (ChIP)-seq and compared the results to gene expression data (RNA-seq datasets for Eveland et al., 2013, submitted). We mapped genome-wide occupancy of RA1 and showed that it differently regulates modules of target genes based on spatiotemporal context. Plants expressing complementing RA1 transgenes tagged with HA or YFP were used in parallel experiments. Ear and tassel primordia were collected and tag-specific antibodies were used to pull down RA1 bound to its target loci. Genome-wide analysis of RA1 occupancy revealed thousands of putative binding sites (i.e. peaks significantly enriched (p < 1e-05) compared to input DNA).
