Abstrakt: Background: H 2 O 2 treatment can accelerate grape ripening and mediate changes in histone methylation levels. Histone methylation, as an epigenetic modification, is involved in regulating the expression of genes related to fruit ripening, including H3K27ac, H3K4me1, H3K27me3 and H3K4me3. Among them, H3K27me3 methylation is generally negatively regulated in development, and H3K27 methyltransferase can participate in the development process of fruit by regulate the level of H3K27me3. The H3K27 methyltransferase members in grapes are not yet clear, and a better understanding of their functions contributes to regulating fruit development.
Methods and Results: By analyzing the conserved domains of the grape genome, three H3K27 methyltransferases were identified and named as VvH3K27-1, VvH3K27-2 and VvH3K27-3, respectively. Further analysis included their conserved domains, gene structure, phylogenetic relationship, protein physicochemical properties, chromosome localization, subcellular localization, and cis-acting elements in the promoter region. It is worth noting that all H3K27 methyltransferase genes have a highly conserved SET domain. VvH3K27-2 was localized in the nucleus and H 2 O 2 treatment resulted in a decrease in the expression of these genes.
Conclusion: Three H3K27 methyltransferase genes were identified in grape, which are down-regulated during berry development, and their expression is inhibited by H 2 O 2 treatment. Thus, H3K27 methyltransferase genes are involved in the regulation of fruit development.
