Comparative analysis of small secreted peptide signaling during defense response: insights from vascular and non‐vascular plants

Abstract Small secreted peptides (SSPs) play an important role in modulating immune responses all land plants. However, the evolution of stress peptide signaling different plant phyla remains poorly understood. Here, we compared expression SSP genes pathogen‐induced transcriptomes vascular and non‐vascular We found 13, 19, 15, 28 families that were differentially expressed during infection Physcomitrium patens , Zea mays Brassica napus Solanum tuberosum respectively. A comparative study motifs predicted three‐dimensional structures confirmed similarity SSPs across examined species. In both only RALF family was regulated under infection. also EPFL peptides, which are involved growth development processes angiosperms, P. response to pathogen The search for novel immune‐specific revealed a PSY‐like . treatment with synthetic tyrosine‐modified non‐modified PSY, as well recombinant MEG, validated their roles regulation. Thus, our showed complex nature shed light on regulation lineages

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

Current Biology, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

Plant pathogenic Pseudomonas species naturally antagonize a diverse range of flowering plants. While emerging research demonstrates that isolates belonging to the P. syringae complex colonize hosts, extent which these bacteria infect non-flowering plants like model liverwort Marchantia polymorpha remains unclear. Here, we identify natural associations between viridiflava and polymorpha. isolated from diseased liverworts in wild successfully re-infected M. under pure culture conditions, producing high planta bacterial densities causing prominent tissue maceration. Comparative genomic analysis Marchantia-associated identified core virulence machinery type III secretion system (T3SS) conserved effectors (AvrE HopM1) were essential for infection. Disease assays performed Nicotiana benthamiana further confirmed liverwort-associated an effector-dependent manner. Our work highlights as effective broad host pathogen relies on factors manipulate evolutionarily divergent
