Breeding for reduced seed dormancy to domesticate new grass species.

Introducing new grass species into cultivation has long been proposed as beneficial to increase the sustainability and diversity of productive systems. However, wild species with potential tend to show high seed dormancy, causing slow, poor, and unsynchronized seedling emergence. Meanwhile, domesticated species, such as cereals, show lower seed dormancy, facilitating their successful establishment.

Understanding the Geographic Patterns of Closely-Related Species of (Poaceae) Using Distribution Modelling and Seed Germination Traits.

The sexual species of the Dilatata complex (, , , and ) are closely related phylogenetically and show allopatric distributions, except . These species show microhabitat similarities and differences in germination traits. We integrated species distribution models (SDMs) and seed germination assays to determine whether germination divergences explain their biogeographic pattern.
