A seed coat-specific β-ketoacyl-CoA synthase, KCS12, is critical for preserving seed physical dormancy ($) (Plant Physiol.)

Physical dormancy is a dormancy class caused by a water-impermeable cell layer that prevents seed water uptake. Despite being present in several families, its molecular basis has seldom been addressed. Here, Chai and colleagues identify a β-ketoacyl-CoA synthase (KCS) –one of the enzymes that participate…

The seed germination spectrum of alpine plants ($) (New Phytol.)

Alpine ecosystems include all the environments found above the treeline, the maximum elevation where trees can grow. These environments are known for their low temperatures, unstable substrates, and short growing seasons. However, while germination studies in this ecosystem can be traced back to…

Distribution of seed dormancy classes across a fire-prone continent: effects of rainfall seasonality and temperature (Ann. Bot.)

Seed dormancy controls germination so that it occurs under the most suitable conditions. Different dormancy classes achieve this by allowing germination in response to distinct environmental cues. In fire-prone ecosystems, species with physically dormant (PY) seeds benefit from fire since it breaks their…

The first dormancy profile for a tropical montane forest community (Plant Biol.) ($)

Seed dormancy is a crucial mechanism to synchronize germination with the most suitable environmental conditions. Therefore, assessing its prevalence at the community level allows us to understand how plants adapt to their local environment. In this paper, Athugala and colleagues build the first dormancy…
