Scientists have identified a key gene that helps seeds decide whether to germinate.
The MFT gene stops seeds germinating in the dark or under shady conditions, where their chances of survival would be poor, according to new research from the University of York.
The study, conducted on Arabidopsis, a very close relative of oilseed rape, increases our understanding of one of the most important stages in the life cycle of a plant and may help to improve the seed quality of agricultural crops in the future.

Scientists have known for some time that two plant hormones play an important role in regulating if and when a seed will germinate - “Abscisic Acid” or ABA blocks germination and “Gibberelins” or GA promotes it.
