Histones are protein complexes around which genomic DNA is wrapped; post-translational modifications to histone proteins and alterations of histone protein composition affect transcription. H2A.Z is a widely conserved variant form of histone H2A that has been implicated in various forms of transcriptional…

The range of responses an individual could display is a contribution of the inheritance of gene variants that determine such responses and the environments experienced by the individual itself and prior generations (nongenetic inheritance). In this review, we discuss recent empirical data to help us…

Most cultivated tulips (Tulipa gesneriana) are produced in The Netherlands, which has a temperate climate resembling the Central Asian climate in which they originated. The growth cycle of cultivated tulips starts in autumn, when the bulbs are planted in the field. At that time, all organs, including…

Drought tolerance is a complex trait, and Avramova et al. show that there is more than one way to be drought tolerant. Specifically, they investigate the role of antioxidants in supporting leaf growth in several varieties of drought tolerant maize. As compared to the tolerant lines, drought sensitive…

Flowering at the right time of year is crucial for plant reproductive success, so in many plants the transition to reproductive growth is sensitive to daylength.  In recent years, the daylength-responsive signal that moves from leaves to the shoot apical meristem, florigen (encoded by FLOWERING LOCUS…

The ability of trees to offset carbon emissions has been questioned after a Western Sydney University study found common Australian trees are unable to store as much carbon as previously thought. Published in the Nature Climate Change journal, the research found that Australia's iconic Eucalyptus…

Farmers face falling crop yields and growing food demand. ShutterstockAndrew Borrell, The University of Queensland Climate change and extreme weather events are already impacting our food, from meat and vegetables, right through to wine. In our series on the Climate and Food, we’re looking at…

The seeds and fruits derived from the sexual reproduction of flowering plants constitute the major part of the human diet. Our capacity to generate sufficient crop yield is increasingly compromised by human population expansion, competition for land use, biodiversity loss, and global climate change.…
