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.

Ethylene-mediated regulation of transcriptome and proteome in post-translational modifications during petal senescence in Osmanthus fragrans

Project description:Senescence of Osmanthus fragrans petals is a complex process. It has been shown that ethylene is involved in plant senescence and that treatment of plants with ethylene alters their transcriptome and proteome expression levels. However, we know little about the role played by ethylene in post-transcriptional modifications and the link between post-translational modifications and the proteome. In this study, we analyzed ethylene-induced petal senescence response in O. fragrans using transcriptomic and proteomic approaches. The results showed that ethylene induction led to the up-regulation of genes involved in protein degradation and the down-regulation of amino acid biosynthesis genes in O. fragrans petals, and some genes involved in hormone synthesis and signaling were also up-regulated, including genes related to ROS regulation and genes related to cell wall enhancement. The findings indicate that ethylene can trigger senescence in the petals of O. fragrans. Additionally, ethylene treatment influenced the floral composition of O. fragrans, uncovering the correlation between the aging process of the flower and alterations in its fragrance profile.The transcriptomic and proteomic analyses of ethylene-induced petal senescence in O. fragrans offer theoretical insights into the understanding of plant senescence, and this knowledge will also aid in extending the duration of flower blooming.

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.

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.
