In vitro axenic germination and cultivation of mixotrophic Pyroloideae (Ericaceae)
Pyroloids, forest sub-shrubs of the Ericaceae family, are an important model for their mixotrophic nutrition, which mixes carbon from photosynthesis and from their mycorrhizal fungi. They have medical uses but are...

Grass florets bet-hedge against unpredictable rainfall in arid landscapes
Seed germination in the arid zone is a high-risk event. For grasses specifically, the ancillary bracts of the floret surrounding the seed have been associated with innate dormancy mechanisms, resulting in infrequent...

This Carnivorous Plant Needs Its Home to Burn
Like the mythical Phoenix, the Portuguese Sundew is reborn from ashes, but that's a problem when people protect your habitat from flames.

Germination cues and community assembly in a coastal habitat
Regeneration by seed is a critical process in the life of plants, and germination traits determine the environments that a species can inhabit. Fernández-Pascual et al. study the germination of thirty species from the...
Seed dormancy changes of snowbed species under climate warming
Parental plant growth environment could alter the state of seed dormancy, affecting the timing of emergence and seedling survival. In the context of climate warming, Bernareggi et al. investigate the effects of pre- and...
Dual role of reactive oxygen species in seed physiology (Review)
Reactive oxygen species (ROS) are considered to be detrimental to seed viability. However, recent studies have demonstrated that ROS have key roles in seed germination particularly in the release of seed dormancy and...
Sediment seed banks in freshwater sandstone rock pools
Results suggest that sediment seed banks may represent a significant driver of species persistence in these ecosystems.
Temperature and reproductive success in arabidopsis
Seed yield and dormancy status are key components of species fitness that are influenced by the maternal environment. Huang et al. grow the Arabidopsis thaliana ecotype Burren (Bur), which is adapted to a cool, damp...
Environmental and genetic effects on seed dormancy
Climate may determine changes in seed dormancy in the short and the long term, shaping plant responses to global change. Fernández-Pascual et al. investigate germination in Centaurium somedanum, a narrow endemic...
Effects of herbicide-resistance alleles on weed seed germination
Plant genes enabling arable weeds to survive herbicide applications can have varied effects on the weed life cycle.

Seed dormancy distribution and ecology
In sea beet, Beta vulgaris ssp. maritima, seed dormancy largely controls germination timing, is highly heritable and varies geographically; climate might select for this trait. Wagmann et al. assess geographical...
Parental environment and seed response to karrikinolide
Seeds from different populations of the same species often show distinct germination responses to the smoke-derived chemical karrikinolide (KAR1), thus limiting its potential for use in weed management. Gorecki et al...
Smoking out weeds with karrikinolide
Karrikinolide (KAR1) is a smoke-derived chemical that can trigger seeds to germinate, and shows promise as a tool for flushing out weed seeds from the soil seed bank. Long et al. demonstrate that weeds of Brassicaceae...
