Heat stress can have transgenerational effects on a plant's offspring but how important are the timing and frequency of these events?

What is photoperiodically regulated in Arabidopsis lyrata?
The photoperiod is the period of time that a plant receives light each day. The photoperiod matters to a plant as it contains information about the progress of seasons. Plants use the changing photoperiod as a cue for...

Brachypodium peroxidase and drought tolerance
The peroxidase (POD) family shows functional diversity. Luo et al. demonstrate that Brachypodium distachyon ecotypes have distinct specific POD isozymes. Two POD genes are closely associated with whole-plant response to...

Seed dormancy cycling and mortality in Arabidopsis thaliana
The contribution of variation in seed bank dynamics to local adaptation is not well studied. Postma et al. investigated the extent to which genetic and environmental factors affect dormancy cycling and mortality of...
Natural populations of Arabidopsis thaliana differ in seedling responses to high temperature stress
Little is known about adaptive within-species thermotolerance variation in wild plants despite its likely role in functional adaptation at range limits and in predicting response to climate change. In a new study...

Physiological mechanisms of germination responses
Germination timing, a major determinant of fitness, is extremely sensitive to environmental conditions but the physiological mechanisms regulating it are largely unknown. Barua et al. study Arabidopsis thaliana and find...
Natural variation in arabidopsis stomatal abundance
Our understanding of stomatal development in Arabidopsis thaliana is based on mutants with aberrant, often lethal phenotypes. Through a comprehensive analysis of stomatal abundance in wild A. thaliana accessions...
