Parental plant growth environment could alter the state of seed dormancy, affecting the timing of emergence and seedling survival. In the context of climate warming, Bernareggi et al. investigate the effects of pre- and post-dispersal temperatures on the seed dormancy release and germination requirements of alpine plants.
They conclude that a warmer parental environment will change the germination responses of the seed progeny and that the extent of this change across species could be driven by seed dormancy traits. Transgenerational plastic adjustments of seed germination and dormancy patterns may play a crucial role in future plant adaptation to climate change.
