Involvement of ROS1 in gene expression of imazethapyr-treated Arabidopsis thaliana

ABSTRACT: Purpose: To determine candidate genes involved in the increased susceptibility of ros1 plants to imazethapyr. Results: Our study reveled that that imazethapyr up-regulated genes related to chemical stimulus, secondary metabolism, stress condition, flavonoid biosynthesis and epigenetic processes. We identified 31 candidate genes as putative involved in herbicide detoxification, some of this genes are under epigenetic regulation of ROS1.

mRNA-seq of ros1-3 and ros1-4 with ABA treatment

Project description:To survey transcriptome changes by the mutations of a DNA demethylase ROS1 responding to a phytohormone abscisic acid, we performed the Next-gen sequencing (NGS) associated RNA-seq analysis. Two ROS1 knockout lines (ros1-3, ros1-4; Penterman et al. 2007 [PMID: 17409185]) with the wild-type Col line (wt) were subjected. Three samples (ros1-3, ros1-4 and wt), biological triplicates, ABA or mock treatment, using Illumina HiSeq 2500 system

small RNA profiling of WT, ros1-4, nrpd1 single mutants and ros1-4/nrpd1doubble mutant [small RNA-seq]

Project description:Arabidopsis ROS1 is the first genetically characterized DNA demethylase in eukaryotes. Dysfunction of ROS1 leads to increase in DNA methylation level at thousands of genomic loci. However, the features of ROS1 targets are not well understood. In this study, we identified and characterized ROS1 target loci in Arabidopsis Col-0 and C24 ecotypes. Most ROS1 targets are transposable elements (TEs) and intergenic regions. Compared to other TEs, ROS1-targeted TEs are closer to protein coding genes, suggesting a role for ROS1 in preventing the spreading of DNA methylation from highly methylated TEs to nearby genes. Interestingly, we found that unlike general TEs, ROS1 targets are associated with an enrichment of H3K18ac and H3K27me3, and depletion of H3K27me and H3K9me2. We investigated the antagonism between ROS1 and RNA-directed DNA methylation (RdDM) by identifying and characterizing thousands of genomic regions regulated by both ROS1 and RdDM. Unexpectedly, we uncovered thousands of previously unidentified RdDM targets by analyzing the DNA methylome of ros1/nrpd1 double mutant plants. In addition, we show that ROS1 also antagonizes RdDM-independent DNA methylation at more than a thousand genomic loci. Our results provide significant insights into the genome-wide effects of both ROS1-mediated active DNA demethylation and RNA-directed DNA methylation as well as their interaction in plants.

Transcriptome analysis indicates the involvement of herbicide-responsive and plant-pathogen interaction pathways in the development of resistance to ACCase inhibitors in Apera spica-venti

Project description:Background: The continuous use of the herbicides contributes to the emergence of the resistant populations of numerous weed species that are tolerant to multiple herbicides with different modes of action (multiple resistance) which is provided by non-target-site resistance mechanisms. In this study, we addressed the question of rapid acquisition of herbicide resistance to pinoxaden (acetyl CoA carboxylase inhibitor) in Apera spica-venti, which endangers winter cereal crops and has high adaptation capabilities to inhabit many rural locations. To this end, de novo transcriptome of Apera spica-venti was assembled and RNA-sequencing analysis of plants resistant and susceptible to pinoxaden treated with this herbicide was performed. Results: The obtained data showed that the prime candidate genes responsible for herbicide resistance were those encoding 3-ketoacyl-CoA synthase 12-like, UDP-glycosyltransferases (UGT) including UGT75K6, UGT75E2, UGT83A1-like, and glutathione S-transferases (GSTs) such as GSTU1 and GSTU6. Also, such highly accelerated herbicide resistance emergence may result from the enhanced constitutive expression of a wide range of genes involved in detoxification already before herbicide treatment and may also influence response to biotic stresses, which was assumed by the detection of expression changes in genes encoding defence-related proteins, including receptor kinase-like Xa21. Moreover, alterations in the expression of genes associated with methylation in non-treated herbicide-resistant populations were identified. Conclusion: The obtained results indicated genes that may be involved in herbicide resistance. Moreover, they provide valuable insight into the possible effect of resistance on the weed interaction with the other stresses by indicating pathways associated with both abiotic and biotic stresses.

RNA Sequencing Analysis of Nicol-Het, Nicol-KO and Ros1-KO Caput Epididymal Transcriptomes.

Project description:Purpose: The goal of this study is to detect differentially expressed genes, between Nicol +/- (Nicol-Het), Nicol-/- (Nicol-KO), and Ros1-/- (Ros1-KO) caput epididymis by RNA sequencing Methods: Caput epidiymal mRNA profiles of 14-week-old Nicol-Het, Nicol-KO, and Ros1-KO mice were generated by deep sequencing, in triplicate, using Illumina NovaSeq6000. Results: RNA-seq data identified differentially expressed transcripts. Conclusions: Our results show that the expression of many genes were downregulated in Nicol-KO caput epididymis compared with Nicol-Het one. The gene downregulation of Nicol-KO caput epididymis was similar to that of Ros1-KO one.

The WOPR protein Ros1 is a master regulator of sporogenesis and effector gene expression in the maize pathogen Ustilago maydis [RNA-Seq]

Project description:Goals: characterization of the transcription factor Ros1 in Ustilago maydis Methods: generation of deletion mutants, microscopic observations, ectopic expression of ros1, identification of Ros1 regulated genes by RNAseq and ChIP sequencing Results: Ros1 is not involved in plant colonization but is essential to trigger sporogenesis during late stages of infection. Premature expression of ros1 revealed that Ros1 counteracts the b-dependent filamentation program and induces morphological alterations resembling the early steps of sporogenesis. Transcriptional profiling and ChIP seq analyses revealed that Ros1 affects the expression of about 30 % of all U. maydis genes with 40% being direct targets. Cell wall remodeling and plasma membrane modifications are among the processes affected by Ros1 dependent regulation. Interestingly a large number of b-dependent genes including transcription factors and effector genes involved in biotrophy establishment were downregulated by Ros1 while a subset of novel â??late effectorsâ?? were upregulated. Taken together our results indicate that Ros1 is a master regulator of sporogenesis in U. maydis and that the switch to sporogenesis is accompanied by the differential regulation of 75% of the effector genes. Two samples corresponding to plant material infected with either U. maydis wild type strains FB1 x FB2 or the ros1 deletion strains FB1Dros1 x FB2Dros1 were analyzed in triplicate.
