Histone H3K4 methyltransferase DcATX1 promotes ethylene induced petal senescence in carnation (Dianthus caryophyllus L.)

Project description:Petal senescence is controlled by a complex regulatory network. Epigenetic regulation like histone modification influences chromatin state and gene expression. However, involvement of histone methylation in regulating petal senescence is still largely unknown. Here, we found that the trimethylation of histone H3 at Lysine 4 (H3K4me3) is increased during the ethylene induced petal senescence in carnation (Dianthus caryophyllus L.). The H3K4me3 levels are positively associated with the expression of transcription factor DcWRKY75, ethylene biosynthetic genes DcACS1 and DcACO1, and senescence associated genes (SAGs) DcSAG12 and DcSAG29. Further, we identified that carnation DcATX1 (ARABIDOPSIS HOMOLOG OF TRITHORAX1) encodes a histone lysine methyltransferase which can methylate H3K4. Knockdown of DcATX1 delays ethylene induced petal senescence in carnation, which is associated with the downregulated expression of DcWRKY75, DcACO1 and DcSAG12. While overexpression of DcATX1 exhibits the opposite effects. DcATX1 promotes the transcription of DcWRKY75, DcACO1 and DcSAG12 by targeting to their promoters to elevate the H3K4me3 levels. Overall, our results demonstrate that DcATX1 is a H3K4 methyltransferase that promotes the expression of DcWRKY75, DcACO1, DcSAG12 and maybe other downstream target genes by regulating H3K4me3 levels, thereby accelerating ethylene induced petal senescence in carnation. This study further indicates that epigenetic regulation is important for plant senescence process.

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.

ENAP1 is involoved in the EIN3- mediated ethylene response

Project description:We report that ethylene reduce the ENAP1 binding. 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.

EIN2 mediates histone H3K14 and non-canonical histone H3K23 acetylation in the nucleus in ethylene response [ChIP-seq]

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.
