Memory in the wall: expanding our understanding of the roles of plant cell walls

New Phytologist, Volume 249, Issue 1, Page 56-72, January 2026.
Summary The plant cell wall, while providing mechanical support to cells, also dynamically adjusts its composition and structure in response to cellular and environmental cues. Recent findings indicate that plants exposed to cold stress alter the composition of cell wall polysaccharides and that this altered status primes the plants to overcome future,

FEM Modeling of the Microneedle Insertion Into a Cellular Structure for Microsampling of Plant Fluids

International Journal of Biomaterials, Volume 2026, Issue 1, 2026.
Microneedle‐based access to plant phloem enables sustainable energy harvesting and in situ biochemical sensing, but its performance is limited by defense responses such as callose deposition triggered by mechanical overstimulation of cell walls.

Silicon Promotes Exodermal Casparian Band Formation in Si-Accumulating and Si-Excluding Species by Forming Phenol Complexes. [PDF]

PLoS ONE, 2015
We studied the effect of Silicon (Si) on Casparian band (CB) development, chemical composition of the exodermal CB and Si deposition across the root in the Si accumulators rice and maize and the Si non-accumulator onion.

Morphological constraints on plant‐mediated methane release and oxidation under experimental warming in a peatland and meadow on the Qinghai‐Tibetan Plateau

Functional Ecology, Volume 39, Issue 12, Page 3571-3585, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Alpine meadows and peatlands on the Qinghai‐Tibetan Plateau, respectively, act as sinks and sources of atmospheric CH4. Yet, little is known about plant‐mediated CH4 fluxes in these ecosystems.

Strigolactones Play an Important Role in Shaping Exodermal Morphology via a KAI2-Dependent Pathway

iScience, 2019
Summary: The majority of land plants have two suberized root barriers: the endodermis and the hypodermis (exodermis). Both barriers bear non-suberized passage cells that are thought to regulate water and nutrient exchange between the root and the soil ...

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

New Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Regulatory Programmes Driving Suberin Plasticity Under Aluminium Stress in Barley Roots

Plant, Cell &Environment, Volume 48, Issue 11, Page 7775-7791, November 2025.
ABSTRACT Aluminium (Al) toxicity is a major factor limiting plant growth in acidic soils. The beneficial element silicon (Si) can mitigate some effects of Al. However, the impact of Al on suberized apoplastic barriers in roots is largely unknown while the effects of Si on suberin remain controversial.
