“…In order to analyze expression patterns of known and previously unannotated SSPs during immune response, we re-analyzed four published transcriptomes of phylogenetically distant species: the moss Physcomitrium patens (Physcomitrella), Zea mays , Brassica napus , and Solanum tuberosum (Kwenda et al, 2016; Reboledo et al, 2021; D. Wang et al, 2022; Xia et al, 2023; Figure 1A). These transcriptomes were selected based on the following criteria: 1) the plants were infected with either necrotrophic or hemibiotrophic pathogens; 2) the quality of raw data (see Methods); and 3) RNA-seq analysis was performed at different time points after pathogen inoculation.…”

Peptides play a crucial role in regulating plant responses to stress conditions. Small secreted peptides (SSPs) are known to be involved in immune response and are found in all land plants. However, the evolution of stress peptide signaling remains poorly understood. Here, we compared the pathogen-induced transcriptomes of the moss Physcomitrium patens, Zea mays, Brassica napus, and Solanum tuberosum to gain insight into the role of established SSP families from vascular and non-vascular plants in immune response. We identified 50, 76, 135, and 309 known SSP genes, differentially expressed during infection, in P. patens, S. tuberosum, Z. mays, and B. napus, respectively. In addition, a novel family of bryophyte-specific PSY-like peptides that are differentially regulated under infection was identified. The similarity of SSPs across the examined plant species was validated through a comparative analysis of peptide motifs and predicted three-dimensional structures. However, despite the similar patterns of antimicrobial peptide expression, only the RALF peptide family was differentially regulated under infection in both vascular and non-vascular plants. We also found that EPFL peptides, which are involved in growth and development processes in angiosperms, were differentially regulated in P. patens in response to pathogen infection. Thus, our study showed the complex nature of SSP signaling and shed light on the regulation of SSPs in different plant lineages during infection.

The plant cell wall is dynamically modified during host–pathogen interactions and acts as a crucial factor controlling plant immunity. In the context of recently revised models of plant primary cell walls (PCWs), pectin is considered to be important in determining the mechanical properties of PCWs. A secondary cell wall is present in some cell types and lignin is normally present and acts to strengthen wall rigidity. In this review, we summarize the recent advances in understanding cell-wall-mediated defense responses against pathogens in Brassica napus L. (B. napus). A major part of this response involves pectin and lignin, and these two major cell wall components contribute greatly to immune responses in B. napus. Crosstalk between pectin and lignin metabolism has been detected in B. napus upon pathogen infection, suggesting a synergistic action of pectin and lignin metabolism in regulating cell wall integrity as well as wall-mediated immunity. The transcriptional regulation of cell-wall-mediated immunity in B. napus along with that in Arabidopsis is discussed, and directions for future work are proposed for a better understanding of wall-mediated plant immunity in B. napus.
