<i>Aethionema arabicum</i> dimorphic seed trait resetting during transition to seedlings.

ABSTRACT: The transition from germinating seeds to emerging seedlings is one of the most vulnerable plant life cycle stages. Heteromorphic diaspores (seed and fruit dispersal units) are an adaptive bet-hedging strategy to cope with spatiotemporally variable environments. While the roles and mechanisms of seedling traits have been studied in monomorphic species, which produce one type of diaspore, very little is known about seedlings in heteromorphic species. Using the dimorphic diaspore model Aethionema arabicum (Brassicaceae), we identified contrasting mechanisms in the germination responses to different temperatures of the mucilaginous seeds (M⁺ seed morphs), the dispersed indehiscent fruits (IND fruit morphs), and the bare non-mucilaginous M^- seeds obtained from IND f
