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...
A new study finds increased temperature requirements for germination of heather (Calluna vulgaris) seeds from colder climates.
New research identifies low-cost and time-saving markers of seed deterioration.
Seeds of the moist temperate woodland species Galanthus nivalis and Narcissus pseudonarcissus, which disperse during spring or early summer, germinate poorly in laboratory tests. Newton et al. study seed characteristics and find a distinct typology...
