Seed after‐ripening and dormancy determine adult life history independently of germination timing

Casas, Rafael Rubio de; Kovach, Katherine; Dittmar, Emily; BARUA, DEEPAK; Barco, Brenden; Donohue, Kathleen (Wiley, 2012-03)

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 ...
Maternal effects alter natural selection on phytochromes through seed germination

Donohue, Kathleen; BARUA, DEEPAK; Butler, Colleen; Tisdale, Tracy E.; Dittmar, Emily; Chiang ,George C. K.; Casas, Rafael Rubio de (WileyBritish Ecological Society, 2012-05)

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 ...
Pleiotropy in the wild: the dormancy gene DOG1 exerts cascading control on life cycles

Chiang, George C. K.; BARUA, DEEPAK; Dittmar, Emily; Kramer, Elena M.; Casas, Rafael Rubio de; Donohue, Kathleen (Wiley, 2013-03)

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 ...
