Abstract
Heterosis is the increase in fitness and yield of F1 hybrids derived from a cross between distantly related genotypes. The use of heterosis is one of the most successful crop breeding strategies, but the underlying molecular mechanisms are still poorly defined. There is ample evidence that heterosis is associated with increased rates of photosynthesis and recent analyses have shed light on the underlying biochemical principles. In parallel, the importance of epigenetic chromatin modifications in heterosis has now been established. The first direct links between epigenetic changes and improved photosynthesis have also been demonstrated. As epigenetic engineering is now possible, we discuss the feasibility of altering the epigenetic code to enhance photosynthesis.
