Histone demethylase SlJMJ4 promotes leaf senescence via removal of H3K27 methylation of senescence-related genes in tomato

Project description:SlJMJ4 is a positive regulator of leaf senescence in tomato and mediates ABA-induced leaf senescence by activating the transcription of many genes related to ABA synthesis and signaling, and transcription regulation via removal of their H3K27me3 levels.

Histone demethylase SlJMJ6 promotes fruit ripening by removing H3K27 methylation of ripening-related genes in tomato [RNA-Seq]

Project description:Here, we found that the tomato jmjC domain-containing gene SlJMJ6 encodes a histone lysine demethylase that specifically demethylates H3K27 methylation. Overexpression of SlJMJ6 accelerated fruit ripening in tomato, which is associated with the up-regulated expression of a large number of ripening-related genes. Integrated analysis of RNA-seq and ChIP-seq data identified 55 genes that are targeted directly by SlJMJ6 and transcriptionally up-regulated with decreased H3K27m3 in SlJMJ6 overexpressing (SlJMJ6-OE) fruits. A large number of the SlJMJ6-regulated genes are involved in transcription regulation, ethylene biosynthesis, cell wall degradation, pigment biosynthesis, and hormone signaling. Fourteen ripening-related genes including RIN, ACS4, ACO1, PL, TBG4 were confirmed to be directly regulated by SlJMJ6 through removing H3K27me3. Taken together, these results indicated that SlJMJ6 is a ripening prompting H3K27me3 demethylase that activates the expression of the ripening-related genes by modulating H3K27me3, thereby facilitating fruit ripening in tomato. To our knowledge, this is the first report of the involvement of a histone lysine demethylase in the regulation of fruit ripening.

Alternative mRNA splicing controls functions of the human H3K27 demethylase UTX/KDM6A

Project description:The UTX/KDM6A gene encodes the UTX histone H3K27 demethylase, which plays an important role in mammalian development and is frequently mutated in cancers and particularly, in urothelial cancers. Using BioID technique, we explored the interactome of different UTX isoforms.
