High-order mutants reveal an essential requirement for peroxidases but not laccases in Casparian strip lignification [PDF]

Proceedings of the National Academy of Sciences, 2020
Significance Lignin is a defining polymer of vascular plants and of great physiological, ecological, and economical importance. Yet, its polymerization in the cell wall is still not understood. Lignin polymerizing enzymes, laccases and peroxidases, exist in vast numbers in plant genomes. By focusing on a specific lignin structure, the

De novo assembly of Phlomis purpurea after challenging with Phytophthora cinnamomi

BMC Genomics, 2017
Background Phlomis plants are a source of biological active substances with potential applications in the control of phytopathogens. Phlomis purpurea (Lamiaceae) is autochthonous of southern Iberian Peninsula and Morocco and was found to be resistant to ...

Cross‐Species Plasticity and Divergence Under Alkaline Soil Signature Conditions Differentiating PYE From FIT Target Transcripts in the Arabidopsis thaliana Ferrome

Plant, Cell &Environment, EarlyView.
ABSTRACT Soil pH is an influential abiotic environmental factor. Here, we identify responses to central stimuli associated with calcareous alkaline soils in Arabidopsis and comparatively explore the potential of the closely related Arabidopsis halleri for addressing how plants cope with local soil pH.

Casparian strip diffusion barrier in Arabidopsis is made of a lignin polymer without suberin [PDF]

Proceedings of the National Academy of Sciences, 2012
Casparian strips are ring-like cell-wall modifications in the root endodermis of vascular plants. Their presence generates a paracellular barrier, analogous to animal tight junctions, that is thought to be crucial for selective nutrient uptake, exclusion of pathogens, and many other processes. Despite their importance, the chemical

Endophyte‐induced systemic spatial reprogramming of metabolism in Populus trichocarpa roots under drought

New Phytologist, Volume 251, Issue 1, Page 438-454, July 2026.
Summary Beneficial, facultative endophytes help plants thrive in challenging environments by altering their host's metabolism, but how these cellular scale metabolic changes propagate to the systems biology scale is unknown. In this work, we employed a high‐resolution chemical imaging approach to map metabolic changes at the Populus trichocarpa root ...

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development

Plant, Cell &Environment, Volume 49, Issue 7, Page 3678-3693, July 2026.
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...

Boron deficiency responses in maize (Zea mays L.) roots

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 3, Page 315-329, June 2026.
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.
