What is the biological consequence of natural variations in histone modification in plants? In this issue, genomewide H3K27me3 modification and expression analyses were performed in two Arabidopsis accessions and their hybrid. Results showed that variations of H3K27me3 histone modification between these two accessions correlates negatively with gene expression levels, resulting in allelic bias of the H3K27me3 modification in hybrid. The heterosis in hybrid was compromised upon mutation of CLF that regulates the H3K27me3 modification (see Yang et al., 466–474, for details).
