The broken remains of pectin give clues to the culprit
By tracking how cell walls were loosened, a team has been able to show which enzyme is helping fruit ripen.

The tale of extensins: do these proteins protect plant roots against pathogens?
Scientists share viewpoints on the role of glycoproteins in cell wall network
Dissecting growth responses to gravity and light in poplar trees
Can a new isotropic light device lead to a better understanding of molecular responses to gravitational stimuli?

Thicker leaves, thicker cell walls, low mesophyll conductance
Do differences in structure and anatomy impact mesophyll conductance and photosynthesis of rice leaves?
Microscopes and roots: investigating whether cell wall thickenings are phi (Φ) or “C” shaped
Noccaea caerulescens has some tricks that help it cope with heavy metals.
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 the case of Cardamine hirsuta, that travel is explosive. The plant stores energy in the pericarp of...
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 glycan moiety of extensins is...

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 by the United Nations at the Paris climate change meeting in...

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 examine a chemical that regulates how this happens. Plant cell walls have many...
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...
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 for consumers and industry. The...
