In the wild, seed dormancy promotesfitness by preventing germination before conditions are optimal for plant growth. During crop domestication, however, seed dormancy was selected against to ensure uniform germination upon sowing. Despite this, too little dormancy can be problematic, especially in cereal crops where it causes yield losses due to preharvest germination. Seed dormancy has long been known to be antagonistically regulated by abscisic acid
