Project description:Purpose: To understand the molecular mechanism between PNET2 and NTLs, we generated 35S:NTL-SRDX in pnet2_ab mutants to suppress NTL gene expression and performed the whole genome transcriptome analysis on 4-week-old plants of WT, pnet2_ab, 35S:NTL6-SRDX pnet2_ab, 35S:NTL9-SRDX pnet2_ab, and 35S:NTL12-SRDX pnet2_ab. Conclusions: PNET2 regulates diverse responses by associating with a family of membrane-bound transcriptional factors.
Project description:Using BS-Seq to provide single-base resolution of DNA methylation status in 35S-SUC2 WT and antisilencing mutants (arp6, pie1, h2a.z, idm1, and ros1)
Project description:Arabidopsis emf2 mutants bypass vegetative development and flowering upon seed germination. We introduced a broccoli BoEMF2.1 gene into emf2 mutants and obtained rescued emf2 plants that harbored 35S::BoEMF2.1. We found that BoEMF2.1 can partially rescue the phenotype of emf2 to that of WT. We used microarrays to study the global program of gene expression and to identify genes misexpressed in the Arabidopsis emf2 mutant that had been rescued by 35S::BoEMF2.1.
Project description:Using whole genome bisulfite sequencing to provide single-base resulution of DNA methylation status in 35S-SUC WT, hdp1-1 and hdp2-1, mbd7, idm1, and hdp2mbd7 double mutants
Project description:Arabidopsis emf2 mutants bypass vegetative development and flowering upon seed germination. We introduced a broccoli BoEMF2.1 gene into emf2 mutants and obtained rescued emf2 plants that harbored 35S::BoEMF2.1. We found that BoEMF2.1 can partially rescue the phenotype of emf2 to that of WT. We used microarrays to study the global program of gene expression and to identify genes misexpressed in the Arabidopsis emf2 mutant that had been rescued by 35S::BoEMF2.1. 7-day-old seedlings of WT, transWT, emf2 and rescued emf2 Arabidopsis were used for RNA extraction and hybridization on Affymetrix microarrays.
Project description:1, Using mRNA-Seq to get expression profiling of asi1-1 mutant and WT; 2, Using MethylC-Seq to provide single-base resulution of DNA methylation status in asi1-1 mutant mRNA-Seq: 2 samples examined, Col-0 wild-type with 35S-SUC2 transgene(termed as WT) and asi1-1 mutant (Col-0 background with 35S-SUC2 transgene); MethylC-Seq: 1 sample examined, asi1-1 mutant

Project description:In eukaryotes, heterochromatin is characterized by numerous epigenetic marks, including DNA methylation. Spreading of these marks into nearby active genes must be avoided in order to maintain appropriate gene expression. Here, we uncover Arabidopsis Methyl-CpG-Binding Domain 7 (MBD7) and Increased DNA Methylation 3 (IDM3) as anti-silencing factors that prevent transgene repression and genome-wide DNA hypermethylation. MBD7 preferentially binds to highly methylated, CG-dense regions associated with non-CG methylation and physically associates with other anti-silencing factors, including the histone acetyltransferase IDM1, IDM2, and IDM3. IDM1 and IDM2 were previously shown to facilitate active DNA demethylation by the 5-methylcytosine DNA glycosylase/lyase ROS1. Thus, MBD7 tethers the IDM proteins to methylated DNA, which enables the function of DNA demethylases that in turn establish chromatin boundaries and limit DNA methylation Using MethylC-Seq to provide single-base resolution of DNA methylation status in WT and idm3-1, mbd7-1 mutants Whole genome methylation maps of mbd7-1, idm3-1 and WT (all three are from 35S-SUC transgene background) were generated using BS-seq
Project description:The goal of this study is to clarify the function of ERF13 in the pathway of auxin inducing lateral root development. We isolated total RNA from the roots of 9-day-old WT, 35S:ERF13:MYC and erf3-3 seedlings. New genes act downstream of ERF13 during the lateral root formation are discovered.
