Comparisons of two receptor pathways in a single cell-type reveal features of signalling specificity.

The paper compares two receptor pathways in Arabidopsis root endodermis cells, showing distinct outputs despite similar MPK phosphorylation patterns, suggesting specificity through combinatorial activation and cross-pathway inhibition.

Regulation and Function of a Polarly Localized Lignin Barrier in the Exodermis

This study identifies a polar lignin cap in tomato exodermis that functions similarly to the endodermal Casparian strip but is regulated by distinct transcription factors.

A suberized exodermis is required for tomato drought tolerance

This study identifies exodermal suberization as critical for drought tolerance in tomato, contrasting with Arabidopsis endodermis, and highlights the role of MYB92 and ASFT in this process.

Directed growth and fusion of membrane-wall microdomains requires CASP-mediated inhibition and displacement of secretory foci

This study shows that CASP proteins are essential for organizing secretory foci and ensuring proper cell wall sealing in plant roots.

A peptide-mediated, multilateral molecular dialogue for the coordination of pollen wall formation

The paper reveals a multilateral molecular dialogue involving three cell types that coordinates pollen wall formation through peptide signaling and subtilase activity.

Combined fluorescent seed selection and multiplex CRISPR/Cas9 assembly for fast generation of multiple Arabidopsis mutants

The paper develops a CRISPR/Cas9 toolbox for generating multiple Arabidopsis mutants using fluorescent seed selection and multiplex gRNA introduction.

Extracellular membrane tubules involved in suberin deposition in plant cell walls

The paper shows that extracellular membrane tubules are associated with suberin lamellae formation in plant cells.

Schengen-pathway controls spatially separated and chemically distinct lignin deposition in the endodermis.

The paper shows that endodermal lignin sensing triggers a transcriptional reprogramming leading to chemically distinct compensatory lignin deposition and impacts nutrient homeostasis.

CASP microdomain formation requires cross cell wall stabilization of domains and non-cell autonomous action of LOTR1

The paper shows that LOTR1, an extracellular protease, is required for non-cell-autonomous positioning of Casparian Strip domains in plants, coordinating their formation across neighboring cells.

Spatially Restricted Immune Responses Allow for Root Meristematic Activity During Bacterial Colonisation

The paper shows that spatially restricted immune responses in plant roots allow meristematic activity during bacterial colonization by distinguishing cell-autonomous and non-cell autonomous responses.

GDSL-domain containing proteins mediate suberin biosynthesis and degradation, enabling developmental plasticity of the endodermis during lateral root emergence

The paper identifies GDSL-lipases involved in suberin biosynthesis and degradation, enabling endodermal plasticity during lateral root emergence.

Tissue-autonomous phenylpropanoid production is essential for establishment of root barriers

The paper shows that tissue-autonomous phenylpropanoid production is essential for forming the endodermal Casparian strip and maintaining suberin matrix deposition in roots.

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

This study identifies peroxidases as essential for Casparian strip lignification in Arabidopsis, while laccases are not required for this process.

ROS production by localized SCHENGEN receptor module drives lignification at subcellular precision

The paper identifies a kinase signaling relay that controls ROS production and lignification with subcellular precision by leveraging kinase localization and ROS as a co-substrate.

A two-way molecular dialogue between embryo and endosperm required for seed development

The paper identifies a bidirectional molecular dialogue between embryo and endosperm involving TWS1 and ALE1 to ensure cuticle integrity during seed development.

Molecular mechanism for the recognition of sequence-divergent CIF peptides by the plant receptor kinases GSO1/SGN3 and GSO2.

This paper identifies the molecular mechanism by which plant receptor kinases GSO1/SGN3 and GSO2 recognize sequence-divergent CIF peptides through structural and biochemical analyses.
