According to a recent model, the balance between the activities of ABA and gibberellin in seeds is under both developmental and environmental control such as

a) early stages of seed development, ABA sensitivity is high and gibberellin sensitivity is low, which favors dormancy over germination

b) Later in seed development, ABA sensitivity declines and gibberellin sensitivity increases, favoring germination.

c) Environmental factors such as temperature  and light affect the ABA:GA ratios by activation of the  NCED and GA2ox enzyme, which promotes seed dormancy

d) During an Ambient environment, activation of GA3ox and CYP707A2 inducing dormancy
