Project description:We report that ethylene reduce the ENAP1 binding. We perform Chip-sequencing of ENAP1 using chromatins isolated from 3-day old etiolated Col-0/ein2/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.

Project description:We report that ethylene regulate the ENAP1 binding. We perform a dual cross-linking procedure using the additional cross-linker ethylene glycol bis-succinimidylsuccinate (EGS; Thermo Scientific) along with formaldehyde according to (Pedmale et al. 2016) for Chip-sequencing (ChIPseq) of ENAP1, as well as ENAP1 ChIP- EIN2 reChIPseq (ChIP-reChIPseq), which were used chromatins isolated from 3-day old etiolated Col-0 seedlings treated with ethylene or air gas. Results show that ENAP1 is involved in the EIN2 dependent ethylene response.

Project description:We report that ethylene specifically elevated acetylation of histone H3 at K14 and the non-canonical acetylation of histone H3 at K23. We perform Chip-sequencing of H3K14Ac, H3K23Ac and H3K9Ac using chromatins isolated from 3-day old etiolated Col-0 seedlings treated with ethylene or air gas. Results show that ethylene specifically elevates H3K14Ac and non-canonical H3K23Ac in EIN3 targeted genes that are regulated at the transcriptional level by ethylene.

Project description:Purpose: Next-generation sequencing (NGS) has been used to study the gene expression in different samples under air and ethylene treatment. The goal of this study is to uncover how ENAP1 and H3K23Ac dynamically coordinate with EIN3 to regulate gene expression in response to ethylene.

Project description:We report that CBP20 phosphorylation can regulate root growth in ethylene. We examined the gene expression in roots and shoots of wild type (Col) and cbp20 mutant (in Col background). Ethylene is one of the most essential hormones for plant developmental processes and stress responses. EIN2 is a key factor in ethylene signaling pathway and its function is regulated by phosphorylation. However, the phosphorylation regulation in the ethylene signaling pathway is largely unknown. Here we report the phosphorylation of CBP20 is regulated by ethylene, and the phosphorylation is involved in root elongation. The constitutive phosphorylation format of CBP20 rescues the cbp20 root ethylene hyposensitive phenotype, while the constitutive de-phosphorylation format of CBP20 is unable to rescue the root phenotype of cbp20 in response to ethylene. Genome wide study on ethylene regulated gene expression and microRNA expression in the roots and shoots of both Col and cbp20, together with the result of genetics validation suggest that ethylene induced phosphorylation of CBP20 is involved in root growth and one pathway is through the regulation of microRNAs and their target genes in roots.

Project description:Ethylene induced hyponastic growth in Arabidopsis thaliana F.F. Millenaar L.A.C.J. Voesenek and A.J.M. Peeters Our aim is to identify genes involved in the ethylene induced hyponastic growth. Upon submergence some plant species like Rumex palustris changes its leaf angle (hyponastic growth) and shows enhanced petiole elongation to reach the water surface. In Rumex palustris the hyponastic growth is initiated by an increased concentration of ethylene due to physical entrapment and ongoing ethylene biosynthesis. A proteomics, genomics and genetical approach to improve our understanding of above described flooding-induced responses are not feasible in Rumex palustris since genomic information about this species is limited. However it is possible to use the model plant Arabidopsis thaliana as a tool in flooding research. Natural accessions (Be0 Col Cvi Kas Ler Nd Rld Shah and Ws) show considerable genetic variation in hyponastic growth upon exposure to ethylene Col exhibiting the largest effect (maximum rate after 3 hours) and Ler no effect whatsoever. Using a computer controlled digital camera the hyponastic growth is measured in great detail. Next to ethylene addition also a transfer to low light causes hyponastic growth. This seems to be an ethylene independent pathway because etr1 and ctr1 showed hyponastic growth after transfer to low light. Ethylene and low light showed additive effects in Col. It is likely that ethylene induces more changes in gene expression than only the ones involved in hyponastic growth. By subtracting changes in the Ler expression profile from changes in the Col expression profile we expect to find why Col and Ler respond differently on ethylene by finding specific ethylene induced genes that are involved in hyponastic growth. The expression profile of Col following transfer to low light will be substracted from Col following ethylene addition to distinguish between genes that are involved in hyponastic growth but are not specific for ethylene induced hyponastic growth. There are strong indications in Rumex palustris that other hormones i.e. auxin ABAand GA are involved in the ethylene induced hyponastic growth. Currently mutants in ethylene auxin and ABA biosynthesis and/or signal transduction are screened for hyponastic growth. Preliminary results showed that also in Arabidopsis these other hormones are involved in ethylene induced hyponastic growth. Beside the mutant approach we also started a proteomics and a PCR based differential screen approach. Together with the proposed transcriptome analysis we hope to find new genes involved in ethylene induced hyponastic growth.
