Climate change is expected to cause (sub)arctic plant species to move polewards to track their climatic niche. However, rapid migration requires recruitment from seed, which is rare in arctic regions where most plants...

Reciprocal sowing experiment shows local adaptation and phenotypic plasticity
Reciprocal sowing experiments along environmental gradients allow evaluating local adaptation and phenotypic plasticity as in situ mechanisms to cope with climate change. Sánchez et al. used this approach to infer the...

Antibiotics impact plant traits
Antibiotics used in the livestock industry are released to agricultural fields via grazing animals and manure. From there, they may affect human health due to consumption of antibiotic-exposed crop plants or drinking...
Rice seedling tolerance of salinity and anoxic conditions
Rice (Oryza sativa) can germinate and emerge from anoxic, flooded soils. Salinity, however, compromises seedling establishment. Kurniasih et al. assess the energy requirements for ion regulation in rice coleoptiles...
Early establishment of trees at the alpine treeline: idiosyncratic species responses to temperature-moisture interactions
Alpine treelines globally may move upslope due to climatic warming. Such movement would initially need seed germination and seedling establishment above current treelines. In a recent study published in AoB PLANTS...
How do you wake a sleeping seed?
You can’t just plant a seed and expect it to grow. Chahtane et al. have recently published a review in the Journal of Experimental Botany (JXB) “Primary seed dormancy: a temporally multilayered riddle...

Seed germination of seven desert plants and implications for vegetation restoration
Germination cues reflect the conditions under which a species is likely to succeed in recruitment. In a recent study published in AoB PLANTS, Lai et al. evaluated the seed germination responses of seven desert species...
Ecophysiology of recalcitrant seed persistence
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...
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...
Intra-population variation in physical dormancy
Differences at the individual plant level contributes to physical dormancy-breaking thresholds for five dormant shrub species from fire-prone vegetation
Climate change and germination response
Climate change will disrupt the many interactions between biology and climate, including seed germination.

How rice germinates under water
Rice has the rare ability to germinate and elongate a coleoptile under oxygen-deficient conditions. Here's why.

GPT2, seedling development and sugar signalling
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...
Why small seeds require light to germinate
The influence of light on germination was much stronger in smaller than in larger seeds.
