Transcriptome analysis after ectopically expressing REV in SAM epidermis

ABSTRACT: We ectopically expressed REV in epidermis in ap1 cal background by using AtML1 promoter driven inducible REV(GtoG)-2Venus for RNA-Seq studies. Expression of this transgenes in ap1 cal background gives phenotype similar to their expression in wild-type (WT) backgrounds. For pML1>>REV(GtoG)-2Venus , we sorted the epidermal cells using FACS, after their induction of 6 hours or 16 hours. As a control we collected the epidermal cells after 6 or 16hr induction of pML1::GR-LHG4 in pML1::BFPer background. Q-PCR analysis on extracted RNA showed the successful sorting and regulation of known target genes of REV.

Transcriptome analysis after knocking down class III HD ZIP transcription factors in SAM

Project description:We ubiqoutesly expressed mir165a (pUBQ>>mir165a) in ap1 cal background for RNA-Seq studies. Expression of this transgenes in ap1 cal background gives phenotype similar to their expression in wild-type (WT) backgrounds. We induced the transgenes for 8 hours or 16 hours. As a control we used pUBQ::GR-LHG4 transgeneic line. Q-PCR analysis on extracted RNA showed the successful down regulation of known target genes of class III HD ZIPs.

Ath_Agilent_v2_Riechmann array expression profile AP1-GR ap1cal inflorescences - chx experiment

Project description:This experiment describes gene expression after the activation of APETALA1-GR, to study and identify AP1 target genes. We used a 35S:AP1-GR ap1 cal line to induce a synchronized response activating the AP1-GR fusion protein in ap1 cal inflorescence-like meristems through dexamethasone or dexamethasone+cycloheximide treatment. Tissue samples were collected at 3hrs after the treatment. The expression profiles of the individual samples were then analyzed by gene expression profiling using whole-genome oligonucleotide arrays (Agilent, custom-commercial). We treated inflorescences of 35S:AP1-GR ap1-1 cal-1 plants with a dexamethasone-containing or a mock solution, or with identical solutions that contained in addition 10 M-NM-<M cycloheximide. Tissue was collected 3 hours after the treatment. Samples from each of the four biological replicates resulted in a set of four hybridization pairs: Mock vs. Dex, Mock vs. Chx, Mock vs. Dex+Chx, and Chx vs. Dex+Chx. Dye polarities were switched between biological replicates.

Transcription factor Interplay between LEAFY and APETALA1/ CAULIFLOWER during Floral Initiation

Project description:The transcription factors LEAFY (LFY) and APETALA1 (AP1), together with the AP1 paralog CAULIFLOWER (CAL), control the onset of flower development in a partially redundant manner. This redundancy is thought to be mediated, at least in part, through the regulation of a shared set of target genes. However, whether these genes are independently or cooperatively regulated by LFY and AP1/CAL, is currently unknown. To better understand the regulatory relationship between LFY and AP1/CAL during floral initiation, we monitored the activity of LFY in the absence of AP1/CAL function. We found that the regulation of several known LFY target genes is unaffected by AP1/CAL perturbation, while others appear to require AP1/CAL activity. Furthermore, we obtained evidence that LFY and AP1/CAL control the expression of some genes in an antagonistic manner. Notably, these include key regulators of floral initiation such TERMINAL FLOWER1 (TFL1), which had been previously reported to be directly repressed by both LFY and AP1. We show here that TFL1 expression is suppressed by AP1 but promoted by LFY. We further demonstrate that LFY has an inhibitory effect on flower formation in the absence of AP1/CAL activity. We propose that LFY and AP1/CAL may act as part of an incoherent feed-forward loop to control the establishment of a stable developmental program for the formation of flowers.

REV-ERBa and REV-ERBb function as key factors regulating Mammalian Circadian Output

Project description:The circadian clock regulates behavioural and physiological processes in a 24-h cycle. The nuclear receptors REV-ERBa and REV-ERBb are involved in the cell-autonomous circadian transcriptional/translational feedback loops as transcriptional repressors. A number of studies have also demonstrated a pivotal role of REV-ERBs in regulation of metabolic, neuronal, and inflammatory functions including bile acid metabolism, lipid metabolism, and production of inflammatory cytokines. Given the multifunctional role of REV-ERBs, it is important to elucidate the mechanism through which REV-ERBs exert their functions. To this end, we established a Rev-erba/Rev-erbb double-knockout mouse embryonic stem (ES) cell model and analyzed the circadian clock and clock-controlled output gene expressions. A comprehensive mRNA-seq analysis revealed that the complete knockout of both Rev-erba and Rev-erbb does not abrogate expression rhythms of E-box-regulated core clock genes but drastically changes a diverse set of other rhythmically-expressed output genes. Of note, REV-ERBa/b deficiency does not compromise circadian expression rhythms of PER2, while REV-ERB target genes, Bmal1 and Npas2, are significantly upregulated. This study emphasizes REV-ERBs function to form an essential link between the circadian clock and a wide variety of cellular physiological functions.

Transcriptome profiling of the Nitric Oxide reponsive genes in the Col-0 and ap1/cal mutant

Project description:Despite the importance of Nitric oxide (NO) in both plant and animal development, the regulatory and mechanism of NO function remain elusive. To test if response to NO in the ap1/cal mutant is comparable to the Col-o wild type, we then analysed the genome wide transcriptome profiling of NO responsive genes both in the wild type and ap1/cal seedling using RNA-seq. We observed that about 88% of differential expressed genes in wild type were overlapped with ap1/cal mutant.

We used a pAP1:AP1-GR ap1 cal line to induce a synchronized response activating the AP1-GR fusion protein in ap1 cal inflorescence-like meristems through dexamethasone treatment. Tissue samples were collected immediately after the treatment, as well as subsequent timepoints. The expression profiles of the individual samples were then analyzed by gene expression profiling using whole-genome oligonucleotide arrays (Agilent, custom-commercial)
