Background: Specific chemicals can induce long-lasting disease resistance in plants. These chemicals act by…
Concerted expansion and contraction of immune receptor gene repertoires in plant genomes (Nature Plants)
Plant Science Research WeeklyPlant immunity is crucial for adaptation to pathogen attack and subsequent survival. Two systems support plant immunity. Cell-surface pattern-recognition receptors (PRRs) recognize pathogen-associated molecular patterns (PAMPs) and prompt pattern-triggered immunity. Intracellular nucleotide-binding leucine-rich…
Identification of a cell signaling cascade that regulate s broad-spectrum resistance (Cell Reports)
Plant Science Research WeeklyMany different pathogens attack plants, and many genes have been identified that confer pathogen-specific resistance. In a recent study, Hao et al. identified a signaling cascade that regulates broad-spectrum disease resistance. This pathway is composed of a rice ubiquitin ligase OsPUB73, a VQ motif-containing…

A link between RNA processing and plant immunity
The Plant Cell: In a NutshellPeng, D. Guo, Y. Guo, et al.
Shui Wang, College of Life Sciences, Shanghai Normal University, Shanghai, China
Background: Immune receptors recognize invading microorganisms and activate immune responses. There are two types of immune systems, innate immunity and adaptive immunity. In animals,…
A chromatin remodeler: its role as transcriptional repressor in plant immunity
The Plant Cell: In a NutshellKang et al. (2022) show that Arabidopsis CHROMATIN REMODELING 19 represses transcription and functions in plant defenses against pathogens. https://doi.org/10.1093/plcell/koab318

Background: Plants induce defenses in response…
An N-terminally truncated NLR is functional
The Plant Cell: In a NutshellWu et al. uncover the unexpected role of the truncated NLR NRG1C in negatively regulating plant immunity by antagonizing its full-length NRG1 neighbors.
Background: Plants utilize sophisticated innate immune systems to fight against pathogens. Their genomes encode abundant immune receptors to detect…
Robust transcriptional indicators of immune cell death revealed by spatio-temporal transcriptome analyses (Mol Plant)
Plant Science Research WeeklyMany plants trigger a form of cell death, known as the hypersensitive response (HR), immediately upon pathogen recognition. To minimize damage to the plant, this cell death must be highly localized to the site of attack, while more distal cells survive and activate other immune responses. However, the…
