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...

Delayed aluminium exclusion in signal grass is energy-dependent
The mechanism requires a day or two from exposure to exclude the metal from the intracellular compartment.

Composition and physicochemical properties of outer mucilage from seeds of Arabidopsis natural accessions
Poulain et al. present a dataset describing six traits for polysaccharides extracted from the outer mucilage for 306 natural Arabidopsis thaliana accessions.

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...

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 al. show that plants lacking the ARP2/3 complex have defects...
Creative Destruction: How Death Leads to Function
Marcos Buckeridge explains how death and destruction in sugarcane roots can lead to the development of gas spaces, which improve root function.

Ethylene affects cell wall remobilisation
Seeking to uncover the effects of ethylene on the metabolic process and pectin remobilising capacity of rice (Oryza sativa) that is grown in phosphorus (P)-deficient conditions, Zhu et al. find that ethylene positively...

How does the vital interaction between pollen and pistil work?
How, in molecular terms, does the vital interaction between pollen pollen and pistil work?
Cell-wall pectin and Al resistance
Aluminium (Al) toxicity is one of the factors limiting crop production on acid soils and various resistance mechanisms have evolved in plant species. Cell-wall pectin content is generally lower in Al-resistant than in...
