The GPAT4/6/8 clade functions in Arabidopsis root suberization non-redundantly with the GPAT5/7 clade required for suberin lamellae

This paper shows that GPAT4/6/8 and GPAT5/7 clades in Arabidopsis have non-redundant roles in root suberization, with GPAT5/7 specifically required for lamellated suberin structure.

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.

Air channels create a directional light signal to regulate hypocotyl phototropism

The paper shows that air channels in Arabidopsis hypocotyls enhance light scattering, creating a gradient that regulates phototropism through auxin distribution.

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.

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.

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.

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.

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.

Phosphorylation by Aurora B kinase regulates caspase-2 activity and function

This study identifies Aurora B kinase-mediated phosphorylation of caspase-2 at S384, which inhibits its catalytic activity and apoptosis function during mitotic catastrophe.
