A close-up view of Cardmine hirsuta’s flight jacket

Being rooted, plants have very little opportunity to travel. They can as pollen to find a mate, and also as seeds. In...

Lichen algae remodel their cell walls in response to drying

Lichen algae respond to desiccation with both a controlled collapse of their cell walls and a bit of biochemical remodelling.

Growing biofuels in marginal land

A problem with growing biofuels is that they can take land needed for food. What happens when you start growing biofuels on marginal land where food crops are not possible?

Role of extensin arabinosylation in root defence

Extensins are hydroxyproline-rich glycoproteins thought to strengthen the plant cell wall, one of the first barriers against pathogens, through intra- and intermolecular cross-links. The...

Climate Change and Carbon Sequestration in Soils: Can Phytoliths Help?

In October 2018 the Intergovernmental Panel on Climate Change (IPCC) released its report on the feasibility of us keeping under the 1.5°C target suggested...

Functional and chemical characterization of XAF

Plants rely on stiff cells walls for support. But these same cell walls have to be flexible to grow when required. Nguyen-Phan and Fry...

Sink-source imbalance and down-regulation of photosynthesis

Sink-source imbalance could cause accumulation of total non-structural carbohydrates (TNC) and down-regulation of photosynthesis. Sugiura et al. investigate how sink-source imbalance causes photosynthetic down-regulation...

Arabinogalactan proteins (AGPs) and pectins in apple fruits during postharvest storage

Changes in the arrangement of cell wall components determine cell wall properties (integrity, stiffness), thereby affecting the macro properties of fruits, which are important...

ARP2/3 complex links cell wall assembly and auxin distribution

The protein complex ARP2/3 is responsible for nucleating actin, and its loss results in multiple defects in young seedlings of Arabidopsis thaliana. Sahi et...

Cell wall chemistry determines shoot Ca and Mg concentrations

Linear relationships between shoot magnesium concentration (shoot) and shoot calcium concentration (shoot) are commonly reported among angiosperm species growing together. White et al. present...

Plants from different climates can react to drought in similar ways

How do plants react when circumstances change? One method can be to evolve a local adaptation. Another can be be phenotypic plasticity,...

Not All Pine Needles Are Identical: Lower Crown Loss in Pinus radiata

When fungal infection comes to Pinus radiata, it can run through the bottom of the crown of the tree, removing its leaves....

How do you get more DNA down a pollen tube?

A common event for flowering plants is whole genome duplication (WGD), where a plant gets extra chromosomes. It’s often studied in mature...

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts

Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow...
