Dominant tree species in northern temperate forests, for example oak and beech, produce desiccation-sensitive seeds. Despite the potentially major influence of this functional trait on the regeneration and distribution of species under climate change,...
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 embryogenesis, as well as in protection from pathogens.
Differences at the individual plant level contributes to physical dormancy-breaking thresholds for five dormant shrub species from fire-prone vegetation
Climate change will disrupt the many interactions between biology and climate, including seed germination.
Rice has the rare ability to germinate and elongate a coleoptile under oxygen-deficient conditions. Here’s why.
Dyson et al. study wild-type A. thaliana and a gpt2 T-DNA insertion knockout line, and find that plants lacking GPT2 expression are delayed in seedling establishment, specifically in the process of cotyledon greening (rather than germination).
The influence of light on germination was much stronger in smaller than in larger seeds.
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 species, using seeds...
