The H3K27me3 histone mark correlates with repression of colour and aroma development post-harvest in strawberry fruit.

ABSTRACT: Strawberry ripening is non-climacteric, and post-harvest fruit enter senescence and deteriorate rapidly. Chilled storage induces transcriptome-wide changes in gene expression, including down-regulation of aroma-related genes. Histone marks are associated with transcriptional activation or repression; the H3K27me3 mark is mainly associated with repression of gene expression. Here genes associated with H3K27me3 were identified through ChIP-seq in ripe red strawberry fruit at harvest and after 5 d of chilled storage in the dark. The number of ChIP peaks increased with storage time, indicating an increased role for this mark in regulation of gene expression following chilled dark storage. Comparing ChIP-seq data with RNA-seq data from the same material identified 440 genes whose expression cor
