Signaling peptides control beneficial and pathogenic plant-microbe interactions
Interactions between organisms, such as those between plants and microbes, require extensive signaling between and within each organism to detect and recognize the partner and elicit an appropriate response. Multiple families of small signaling peptides regulate plant interactions with beneficial or pathogenic microbes, and sometimes both. Some of these signaling peptides transmit information between different cells or organs of the host and allow plants to orchestrate a coordinated response towards microbial mutualists or pathogens. However, not only plants produce signaling peptides required for the interactions. Microbes themselves also secrete peptide signals, which are detected by host receptors and required for infection. Among these are microbial peptides mimicking those of plants, allowing mutualistic or pathogenic microbes to hijack endogenous plant signaling pathways and evade the host immune system. In this review, we provide a comprehensive summary of current knowledge on host- and microbe-derived signaling peptides and their cognate receptors regulating mutualistic and parasitic plant-microbe interactions. Furthermore, we describe how microbes hijack endogenous host signaling pathways, and discuss possible crosstalk between the plant signaling pathways controlling mutualism with those modulating immune responses to pathogens.

Receptor‐like kinase cleavage: molecular mechanism and regulatory functions in plants
Receptor-like kinases (RLKs) are essential in nearly all plant life activities. To date, most RLK research focuses on their plasma membrane functions as holoreceptors. This review introduces a distin...

T2SS in the focus. The authors identify a subtilase that cleaves PAMPs/DAMPs thereby suppressing immune activation.

A type II secreted subtilase from commensal rhizobacteria cleaves immune elicitor peptides and suppresses flg22-induced immune activation
Eastman, Jiang, and Ficco et al. screen 165 root-associated bacteria for suppression of plant immune activation and growth restriction induced by the peptide immune elicitor flg22. They show that Dyella japonica uses the type II secreted subtilase IssA to cleave the peptide immune elicitors flg22 and AtPEP1 and suppress plant immune activation.
