In the wild, organismal life cycles occur within seasonal cycles, so shifts in the timing of developmental transitions can alter the seasonal environment experienced subsequently. Effects of genes that control the timing of prior developmental events can therefore be magnified in the wild because they determine seasonal conditions experienced by subsequent life stages, which can influence subsequent...
1. Phytochromes regulate seed germination in response to light and temperature, and different phytochromes contribute to germination under different environmental conditions.
2. Using Arabidopsis thaliana mutants with different combinations of non‐functional phytochromes, we tested which phytochromes contribute to germination and other life‐history traits under field conditions and whether that contribution...
•Seed dormancy can affect life history through its effects on germination time. Here, we investigate its influence on life history beyond the timing of germination.
•We used the response of Arabidopsis thaliana to chilling at the germination and flowering stages to test the following: how seed dormancy affects germination responses to the environment; whether variation in dormancy affects adult phenology...
