ABSTRACT: Transcriptomic analysis of a dne1-1 mutant, two overexpressors of DNE1 (P35S-GFP::DNE1), an overexpressor of DNE1_D153N (35S:GFP-DNE1_D153N), and vcs-6. Biological triplicates of 14 days old seedlings were analyzed.
Project description:Characterization of the impact of TT2 or MYB5 overexpression on gene expression. Col 0 plants were compared to 35S::TT2 and 35S::MYB5 overexpressors in control conditions
Project description:To identify genomic targets involved in the EML-dependent control of seed development, we performed ChIP-chip using whole genome Arabidopsis tiling arrays from p35S::EML1-GFP seedlings using GFP antibodies. The analysis showed that EML1 displayed preferential binding to transposable elements (TEs), while showing no preference for protein coding genes.
Project description:Genome-wide target genes of PPD2 were identified through ChIP-seq on Arabidopsis cell cultures. For ChIP-seq, PPD2 was fused to the GSyellow TAP tag and expressed from the 35S promoter. The p35S:PPD2-GSyellow construct was transformed into Arabidopsis thaliana PSB-D cell culture. ChIP was performed using anti-GFP antibody (abcam290).
Project description:AtACINUS protein is involved in regulation of alternative transcription and splicing(AS). Identifying interaction partners and protein complex compositions for AtACINUS can produce valuable information on the mechanisms by which they regulate transcription and AS, as well as post-translational modifications on AtACINUS. A homozygous 35S::AtACINUS-GFP/acinus-2 plant was selected for similar protein expression level to the endogenous AtACINUS protein of wild-type plants using a native α-AtACINUS antibody. We isolated putative AtACINUS interaction partners from young Arabidopsis seedlings using the native α-AtACINUS antibody. Plants expressing TAP-GFP under 35S promoter were used as controls.

Project description:Total RNA was extracted from samples including 35S::CNT1-NLS-YFP;cry1 and 35S::CNT1-G283E-NLS-YFP;cry1 seedlings grown in continuous blue light and subjected to high throughput sequencing. Previous studies reported that the C-terminal domain of CRY1 regulates hypocotyl elongation and blue light-regulated genes. This study reveals that CNT1 overexpression also regulates blue light-regulated genes, supporting the role of CNT1 in hypocotyl elongation at transcriptomic level. mRNA from blue light-grown CNT1 or CNT1 variant (G283E) overexpressors was sequenced to analyze the genes regulated by CNT1.
Project description:Purpose: To understand MAC3BQ77A/D81A induced abnormal immunity, we performed the whole genome transcriptome analysis on 7-day-old seedlings of WT, 35S:MAC3BQ77A/D81A-GFP. Conclusions: MAC3BQ77A/D81A positively regulates immune response.

Involvment of L-Aspartate oxidase gene using T-DNA mutant (SAIL1145_B10) and overexpressor lines (promotor 35S, vector PCW162) at the same developmental stage (12 leaves) - Study of the biosynthesis of NAD in Arabidopsis.

Project description:In this Data Report, we provide an immunoprecipitation (IP)-based analysis of the HDA19 interactome in etiolated Arabidopsis seedlings. We believe that the interactome presented here provides a valuable resource for follow-up research on novel interacting partners of this central protein. The material used for this experiment was derived from hypocotyls of 6-day-old etiolated Arabidopsis seedlings. The dataset contains a total of 6 files, 3 independent biological replicates of each Col-0 (control plants) and 35S::HDA19-GFP plants.
