Impact of global warming on the seasonal patterns of TIP3 protein expression and dormancy in buried seeds of the Arabidopsis ecotype Cvi. Seeds were buried in pots at opposite ends of a thermogradient tunnel so they experienced ambient temperature conditions or ambient +2.5°C the projected temperature for 2080. (a) Soil temperatures at seed depth. (b) TIP3 protein profiles in seeds undergoing dormancy cycling under both temperature regimes. (c) Percentage radicle emergence from recovered seeds on water or 10‐mM KNO₃ at 5°C in the light. Seed data are mean ± SE (n = 3). Absence of error bars indicates SE is smaller than the symbol
