Background Post-translational modifications of histones affect chromatin state and gene expression.
Histone lysine butyrylation and crotonylation.
Histone acetylation/deacetylation is an essential process in the epigenetic regulation of diverse biological processes, including environmental stress responses in plants [–].
What they did
Mapped Kbu/Kcr sites by MS and ChIP-seq in rice and compared to H3K9ac with transcriptomes under stress.
What they found
Many Kcr sites on H3/H4; Kbu/Kcr resemble acetylation distribution and change with metabolic stress.
The limits
What it doesn't show
Does not prove every site is required for a specific stress phenotype.
