A fungal pathogen manipulates phytocytokine signaling for plant infection

This study identifies a fungal effector that suppresses plant immunity by enhancing phytocytokine signaling, facilitating pathogen infection.

The sulfated peptide CLEL6 is a negative regulator of anthocyanin biosynthesis in Arabidopsis thaliana

This study identifies CLEL6 as a sulfated peptide that inhibits anthocyanin biosynthesis in Arabidopsis, dependent on proteolytic processing, sulfation, and RGI receptor signaling.

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.

The Phtheirospermum japonicum isopentenyltransferase PjIPT1a regulates host cytokinin responses in Arabidopsis

This study identifies PjIPT1a as a key gene in Phtheirospermum japonicum that produces cytokinins to induce host hypertrophy during parasitism.

Precursor processing by SBT3.8 and phytosulfokine signaling contribute to drought stress tolerance in Arabidopsis

This study identifies SBT3.8 and phytosulfokine signaling as mechanisms enhancing drought stress tolerance in Arabidopsis through post-translational processing of proPSK1.

Subtilase activity in the intrusive cells mediates haustorium maturation in parasitic plants

The study identifies subtilase activity in intrusive cells as critical for haustorium development and auxin-mediated host-parasite connections in Phtheirospermum japonicum.

Subtilase-mediated activation of CLEL peptides involves several processing events in consecutive compartments of the secretory pathway

The paper shows that CLEL6 and CLEL9 peptides in Arabidopsis undergo multiple processing steps in the secretory pathway involving subtilases SBT6.1 and SBT3.8.

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.

The systemin signaling cascade as derived from phosphorylation time courses under stimulation by systemin and its inactive Thr17Ala (A17) analog

This study uses phosphoproteomic profiling to reconstruct the systemin signaling cascade, identifying kinase/phosphatase substrates and regulatory interactions in plant wound response.
