Arabidopsis cysteine protease RD19 limits RBOHD-generated ROS production in pattern triggered immunity

This study shows RD19 limits RBOHD-generated ROS in PTI by regulating its accumulation, and identifies AED3 and AED2/ASPG1 as potential RD19 substrates.

Plant pathogens cleave 2′cADPR to suppress TIR immune signaling

This study shows that XopQ, a bacterial virulence protein, cleaves 2'cADPR to suppress plant TIR immune signaling and promote pathogen virulence.

Conserved TIR-only proteins drive transcriptional defense and basal immunity in dicot and monocot plants

This study identifies conserved TIR-only proteins in dicots and monocots that promote basal immunity and transcriptional defense independently of NLR pathways.

Small Molecule Binding to EDS1/PAD4 in LRR-RP-Mediated Pattern-Triggered Immunity

The paper identifies small molecule binding to EDS1 and PAD4 as critical for LRR-RP-mediated PTI, with distinct roles in early and late immune responses.

Cooperation between a root fungal endophyte and host-derived coumarin scopoletin mediates Arabidopsis iron nutrition

This study shows that the fungal endophyte Macrophomina phaseolina interacts with the coumarin scopoletin to enhance Arabidopsis iron nutrition by converting it into iron-chelating esculetin.

GH25 lysozyme mediates tripartite interkingdom interactions and microbial competition on the plant leaf surface

This study identifies GH25 lysozyme from a yeast as a mediator of tripartite interkingdom interactions that shape microbial competition on plant leaf surfaces.

An EDS1 EP-domain surface mediating timely transcriptional reprogramming of immunity genes

The paper identifies an EDS1 EP-domain surface critical for timely transcriptional reprogramming of immunity genes, revealing its role in blocking bacterial virulence via TNL receptor signaling.
