How Do Seeds Save for a Rainy Day?
Timing is everything. For seeds it's a matter of life or death.

Global warming and earlier flowering: a thermogradient tunnel experiment
Winter annual Arabidopsis ecotypes have a distinct advantage over summer annuals in expected global warming scenarios.

Deacclimation kinetics as a quantitative phenotype for delineating the dormancy transition and thermal efficiency for budbreak in Vitis species
Perennial plants use bud dormancy as a strategy to survive stressful environments, such as cold temperatures during winter. This strategy is dependent on the ability of the dormant bud to track the length of winter...

Within- and trans-generational plasticity: seed germination responses to light quantity and quality
Plants respond not only to the environment in which they find themselves, but also to that of their parents. The combination of within- and trans-generational phenotypic plasticity regulates plant development. The light...
Cell cycle arrest in plants
In the cell cycle, the G1 phase can be like a prison, where plant cells are arrested, unable to divide. These cells have been arrested for different reasons, serving sentences of different lengths. So how and why did...

Molecular mediation of photoperiodic control in activity-dormancy tree growth cycles
This review presents the latest findings to provide insight into the molecular mechanisms that underlie how photoperiodic and temperature signals regulate seasonal growth in trees.

Cherry fruit developmental analysis
Evaluating genetic and environmental effects upon sweet cherry cultivars differing in seasonal duration and fruit size, Gibeau et al. employ photographic measurements to apply a framework of biological time indices...
Population variation in germination strategies in an edaphic specialist
Endemic species in biodiversity hotspots are often dependent on edaphic conditions and germination strategies that allow them to persist under climatically variable conditions. Torres-Martinez et al. tested whether...
Germination responses to pre-dispersal light and post-dispersal cues
Should seeds respond to their parents’ environments or their own? Leverett et al. hypothesize that germination would respond more strongly to a post-dispersal vegetative canopy than a pre-dispersal canopy, because a...
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...
Redox changes, dormancy breaking and ageing of seeds
Loss of seed viability has been associated with deteriorative processes that are partly caused by oxidative damage. The breaking of dormancy, a seed trait that prevents germination in unfavourable seasons, has also been...
Global 5-methylcytosine alterations in DNA during ageing of seeds
This study finds that DNA methylation and 5-methylcytosine play key roles in determining the ageing and viability of stored recalcitrant seeds.
Germination and ultrastructural studies of seeds produced by a fast-growing, drought-resistant tree: implications for its domestication and seed storage
Moringa oleifera, or miracle tree, is known in many parts of the world for its multiple uses as an agroforestry crop. However, seeds of this species lose their viability within 6 to 12 months of harvest, and thus...
