The study implies that the generally overlooked role of storage within the plant economic spectrum represents an important dimension of plant strategy.

Direct fluorescence imaging of cell walls in plant roots and stems
Microscopy methods developed in the 1960s are still commonly used in plant science today but new low-cost techniques offer big advantages.

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.

SLAD: Subero-lignified apical deposit in the root tip
Morphological response of radish (Raphanus sativus, Brassicaceae) roots exposed to toxic concentration of copper (Cu) include many root growth changes. Kováč et al. find that such changes are coupled with the formation...

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...
The cell biology of secondary cell wall biosynthesis
What is it that makes a plant get up and stay up? A new review looks at the creation of secondary cell walls. These microscopic features are the key to understanding the architecture of the plants we see around us.

Warming and elevated CO2 alter the suberin chemistry in roots
The decomposability of fine roots and their potential to contribute to soil carbon (C) is partly regulated by their tissue chemical composition. In a recent Editor’s Choice article published in AoB PLANTS, Suseela et al...

New insights into the formation of silica aggregates in sorghum roots
Even though silica and lignin can provide comparable stiffness, they cannot be considered as structural equivalents due to contrasting hydrophobicity.
Stomatal cell wall composition: distinct structural patterns in different phylogenetic groups
Stomata are pores regulating gas exchange in land plants. Stomatal morphology has remained largely consistent through ∼400 million years of plant evolution, though cell wall composition has changed. Shtein et al...
Silicon enhances cellular defences in root tissues of cotton after pathogen inoculation
Silicon has been shown to enhance the resistance of plants to fungal and bacterial pathogens, however the underlying mechanisms have not been studied in detail in most plants. Whan et al. compare cellular and...
Cell biology of lignification in higher plants
A review of current understanding of lignin biosynthesis and polymerisation.

Wood components and Dutch elm disease tolerance
Ďurkovič et al. examine two elm hybrids with contrasting survival strategies upon infection with the current prevalent strain of Dutch elm disease.
Biomechanical responses of hemlock to herbivory
Soltis et al. study the impact of feeding by hemlock woolly adelgid, Adelges tsugae, on the biomechanics of eastern hemlock trees, Tsuga canadensis.
Lignin and/or suberin? Lignin!
For as long as the Casparian strip (CS) – an impervious component of the endodermal cell wall that blocks the passive flow of water and solutes into the vascular tissues of a plant – has been known (discovery credited...
