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

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.

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

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.

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.

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.
