TREE1-EIN3 mediated transcriptional repression inhibits shoot growth in the response to ethylene in the Histone H3K23 acetylation- and EIN3- mediated ethylene response

Project description:We report that ethylene enhances the TREE1 binding. We perform ChIP-sequencing of TREE1 using chromatins isolated from 3-day old etiolated pTREE1:TREE1-GFP seedlings treated with ethylene or air gas. Results show that ethylene enhances TREE1 binding in ethylene down regulated genes.

We perform Chip-sequencing of ENAP1 using chromatins isolated from 3-day old etiolated ein3eil1 seedlings treated with ethylene or air gas. Results show that ethylene reduce ENAP1 binding in TSS region of EIN3 targeted genes that are regulated at the transcriptional level by ethylene.

Ethylene-insensitive5 encodes a 5'->3' exoribonuclease required for regulation of EIN3-targeting F-box proteins EBF1/2

Project description:thylene is a gaseous plant growth regulator that controls a multitude of developmental and stress responses. Recently, the levels of Arabidopsis EIN3 protein, a key transcription factor mediating ethylene-regulated gene expression, have been demonstrated to increase in response to the presence of ethylene gas. Furthermore, in the absence ethylene, EIN3 is quickly degraded through a ubiquitin/proteasome pathway mediated by two F box proteins, EBF1 and EBF2 (1-3). Here, we report the identification of ETHYLENE INSENSITIVE5 as the 5'->3' exoribonuclease XRN4. Specifically, we demonstrate that EIN5 is a component of the ethylene signal transduction cascade acting downstream of CTR1 that is required for ethylene-mediated gene expression changes. Furthermore, we find that the ethylene insensitivity of ein5 mutant plants is a consequence of the over-accumulation of EBF1 and EBF2 mRNAs resulting in the under-accumulation of EIN3 even in the presence of ethylene gas. Together, our results suggest that the role of EIN5 in ethylene perception is to antagonize the negative feedback regulation on EIN3 by promoting EBF1 and EBF2 mRNA decay, which consequently allows the accumulation of EIN3 protein to trigger the ethylene response.

Transcription profiling of Arabidopsis wild type and ein3-1eil1-1mutant seedlings grown in the dark

Project description:Ethylene is a gaseous hormone that plays important roles in plant growth, development and stress responses. EIN3 was identified as a plant-specific transcription factor and its protein level rapidly increases upon ethylene treatment. We found that activation of EIN3 and EIN3-like 1 (EIL1) is both necessary and sufficient for ethylene-induced enhancement of seedling greening, as well as repression of the accumulation of protochlorophyllide, a phototoxic intermediate of chlorophyll synthesis. Therefore, comparation of the Wt and ein3-1eil1-1 mutant etiolated seedlings' gene expression at genome wide will be helpfull for us to find the EIN3/EIL1 target genes in chlorophyll biosynthesis pathway. Here we used microarrays to detail the global gene expression under the regulation of EIN3/EIL1.Here we used microarrays to detail the global gene expression under the regulation of EIN3/EIL1. Experiment Overall Design: 4 days dark grown Wt and ein3-1eil1-1 (AT3G20770, AT2G27050) double mutant seedlings were collected for isolation RNA. Standard Affymetrix protocal and 25K Affymetrix chip (ATH1) were used for Microarry hybridization.

Ethylene promotes root hair growth through coordinated EIN3/EIL1 and RHD6/RSL1 activity in Arabidopsis

Project description:Root hairs are an extensive structure of root epidermal cells and are critical for nutrient acquisition, soil anchorage, and environ- mental interactions in sessile plants. The phytohormone ethylene (ET) promotes root hair growth and also mediates the effects of different signals that stimulate hair cell development. However, the molecular basis of ET-induced root hair growth remains poorly understood. Here, we show that ET-activated transcription factor ETHYLENE-INSENSITIVE 3 (EIN3) physically interacts with ROOT HAIR DEFECTIVE 6 (RHD6), a well-documented positive regulator of hair cells, and that the two factors directly coactivate the hair length-determining gene RHD6-LIKE 4 (RSL4) to promote root hair elongation. Transcriptome analysis further revealed the parallel roles of the regulator pairs EIN3/EIL1 (EIN3-LIKE 1) and RHD6/ RSL1 (RHD6-LIKE 1). EIN3/EIL1 and RHD6/RSL1 coordinately en- hance root hair initiation by selectively regulating a subset of core root hair (H) genes. Thus, our work reveals a key transcriptional complex consisting of EIN3/EIL1 and RHD6/RSL1 in the control of root hair initiation and elongation, and provides a molecular framework for the integration of environmental signals and in- trinsic regulators in modulating plant organ development.

1-aminocyclopropane-1-carboxylic acid (ACC)-induced gene expression in wild-type Col-0, mutant upl3 upl4, mutant ein3-1, and mutant upl3 upl4 ein3-1 Arabidopsis thaliana plants

Project description:The plant hormone ethylene is involved in plant developmental, stress and environmental signalling. The ethylene signalling pathway is modulated by the master transcription factor EIN3. Here we examined the involvement of proteasome-associated UPL3 and UPL4 ubiquitin ligases in ethylene-responsive gene expression. We reveal that in absence of functional UPL3 and UPL4, plants show constitutive and enhanced activation or repression of ethylene-responsive genes in an EIN3-dependent manner. Ten-day old Arabidopsis thaliana seedlings of wild-type Col-0, mutant upl3 upl4, mutant ein3-1, and mutant upl3 upl4 ein3-1 were grown on MS media in an environmental chamber with 16/8 hour day/night light regime (120 mol m-2 s-1 light intensity) and 22 degrees Celsius. Seedlings were then transferred to 6-well plates and floated on the surface of water or 50 uM 1-aminocyclopropane-1-carboxylic acid (ACC). After 3 hours seedlings were harvested and for each treatment ~50 seedlings were pooled together into a single biological repeat. In total three independent biological repeats were collected. After harvesting seedlings were briefly dried on tissue and immediately frozen in liquid nitrogen until further analysis.
