Stepwise and lineage-specific divergence of a major immune co-chaperone complex in leptosporangiate ferns

The paper examines the evolutionary divergence of the RAR1-SGT1 chaperone complex in leptosporangiate ferns, identifying key residues that dictate binding specificity and revealing a stepwise evolutionary pathway.

Herbaria provide a valuable resource for obtaining informative mRNA

This study demonstrates that RNA from herbarium specimens can be used for transcriptomics, validating the functional use of archival mRNA from a 1956 plant specimen.

Canonical NLR immune receptor architecture enforces EDS1-dependency onto divergent TIR domains

The paper shows that NLR immune receptor architecture enforces EDS1-dependency on diverse TIR domains in plants.

A helper NLR channels organellar calcium to trigger plant immunity

This study identifies NRG1 as a plant NLR receptor that targets chloroplasts to trigger immunity by channeling stromal calcium into the cytosol, revealing a novel mechanism for organelle-specific immune signaling.

Conserved effectors underpin the virulence of liverwort-isolated Pseudomonas in divergent plants

The paper identifies conserved virulence factors in Pseudomonas viridiflava that enable infection of both liverworts and flowering plants.

A Necrotizing Toxin Promotes Pseudomonas syringae Infection Across Evolutionarily Divergent Plant Lineages

This study identifies syringomycin as a key necrotizing toxin that enables Pseudomonas syringae to infect diverse plant lineages, including non-flowering species.

An environment-responsive SCLA-type GRAS protein controls reproductive strategy in Marchantia polymorpha

This study identifies MpGRAS7, an SCLA-type GRAS protein in Marchantia polymorpha, as a key regulator of reproductive strategy in response to environmental cues.
