Genome-wide interrogation of genetic requirements for root colonization by CRISPRi-seq in Bacillus subtilis

The paper uses CRISPRi-seq to identify genes required for Bacillus subtilis root colonization in Arabidopsis thaliana, revealing roles in cell envelope remodeling and metabolic shifts.

Mechanical cues trigger phellem differentiation during barrier transition

This study shows mechanical cues trigger phellem differentiation in Arabidopsis roots during barrier transition.

Imaging of specialized plant cell walls by improved cryo-CLEM and cryo-electron tomography

The paper improves cryo-CLEM and cryo-ET techniques for imaging plant cell walls with enhanced precision and reduced contamination, enabling detailed structural analysis of root-specific features.

Minimum requirements for reprogramming and maintaining cell fate in the Arabidopsis root

The paper identifies SHORTROOT and CIF2 as sufficient to induce and stabilize an endodermis-like state in Arabidopsis root sub-epidermal cells through non-cell-autonomous signaling.
