Phytosulfokine signaling modulates salt stress responses and cell wall remodeling in Arabidopsis

This study identifies Phytosulfokine (PSK) signaling as a regulator of salt stress responses and cell wall remodeling in Arabidopsis through proteomic and functional analyses.

Systematic proteomics identifies a conserved mechanism for polar targeting of plant cortical proteins

The paper identifies a conserved mechanism for polar protein targeting in plants using proteomics and shows PAT19 mediates SOSEKI1 membrane localization in Arabidopsis and other species.

Structural and functional insights into the role of Cysteine-Rich Receptor-Like Kinase 18 (CRK18) in Arabidopsis

This study investigates CRK18 homodimerization and redox regulation in Arabidopsis, revealing its role as a negative regulator of nematode infection.

Subnuclear cofactor partitioning underlies auxin-dependent transcriptional regulation

The paper identifies a biochemical mechanism by which the MpARF1 transcription factor activates gene expression through subnuclear clustering and Mediator complex recruitment, revealing an evolutionary innovation in auxin response.

Redox-dependent extracellular interaction networks of Cysteine-Rich Receptor-Like Kinases

This study identifies ROS-dependent dimerisation networks of CRKs in Arabidopsis, showing CRK28 as a redox-sensitive hub linking extracellular redox signals to immunity and senescence.

High resolution, proteome-wide mapping of subcellular protein localization in plants

The paper presents an experimental strategy to map subcellular protein localization in plants using mass spectrometry, annotating thousands of proteins across multiple species and demonstrating conservation and dynamic changes.
