Polploidy is a common feature of many plants, and in addition some plants exist as intra- and interspecific hybrinds. Such plants display growth vigour, and genes involved in metabolism and energy, photosynthesis and starch accumulation are upregulated compared to the parents. This study examines the mechanistic basis of increased growth, and reports that epigenetic modifications of circadian clock regulators mediates the expression of genes in photosynthetic and metabolic pathways.
