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...
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...
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...
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...
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...
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...
