Regulation of anisotropic cell elongation in Arabidopsis
If a plant wants to grow, it needs reliable anisotropic cell elongation*. Getting the cells to elongate has a couple of constraints. There is vacuolar turgor pressure, the pressure from the vacuole in the cell pushing the contents of the cell up against the cell wall. And there’s the cell wall, which needs to limit […] More
Subtle variation in shade avoidance responses has profound consequences for plant competitiveness
There is limited knowledge on how variation in plastic responses plays a role in determining plant competitiveness. To address this issue, Bongers et al. combine experimentations and simulation modelling to test competitiveness for light in Arabidopsis thaliana growing in dense stands. Plant plasticity was represented by changes in leaf angle and petiole elongation in response […] More
The autonomous flowering-time pathway pleiotropically regulates seed germination
Despite some degree of functional divergence between the regulation of flowering and germination by autonomous-pathway genes, the autonomous pathway is highly functionally conserved across life stages. More
ePlant: A Comprehensive Data Visualization Tool for Plant Biologists
The advent and breadth of bioinformatics resources have made scientist’s jobs easier. Before jumping into wet lab work, they are able to parse gene targets and construct better hypotheses. Several groups and research institutes have taken the initiative to provide datasets, tools, algorithms, open source code, and visualization platforms. A comprehensive study of a gene […] More
Experiments versus real-world studies
How close are experiments to nature? The answer isn’t clean cut, partly because nature is messy. More
Early Arabidopsis root hair growth stimulation by pathogenic strains of Pseudomonas syringae
While the most common plant cell response to pathogens is growth arrest, root hair cells can perform the opposite reaction. More

Arabidopsis gene expression in hypobaria
Extreme hypobaria represents an environment that is mostly outside of the evolutionary experience of terrestrial plants, and yet hypobaria may be a part of plant habitats in support of human space exploration. A greenhouse on the surface of Mars, as well as in transit vehicles and space habitats, can be envisioned to operate below the […] More
The Switch To Generation Sex…
Hugh Dickinson on a new article in Science that sheds more light on the Alternation of the Generations. When does a diploid plant decide to become a haploid? Anyone who has sat in a botany class from high school onwards will be familiar with the idea of the ‘Alternation of Generations’. In this botanical circle […] More
Hooray for the hydathode!
There’s more than one way for a pathogen to gain access to healthy leaf. More

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 waiting to be unlocked” where they look into the period between ripening and germination. Obviously, this is going to rely a lot […] More
Every dog has its day
One of the great hopes of the 1980s (and as far back as the 1940s) was that one plant species would be typical of all plants and could be used as a model for the entirety of plant biology. The plant chosen for that singular honour was thale cress – Arabidopsis thaliana (e.g. Maarten Koornneef […] More
