Summary: The rhizosphere microbiome plays an important role in plant development and physiology, including nutrient acquisition and protection against biotic and abiotic stresses. In this study, the researchers investigated the microbial dynamics in the soil of Arabidopsis thaliana plants infected with the foliar pathogen Pseudomonas syringae DC3000 (Pst). The results showed that the changes in soil bacterial composition were mediated by plant-soil feedback and resulted in an activation of SA-related immune response in the plant.

Summary: Recognition of pathogen effectors by nucleotide-binding leucine-rich repeat receptors (NLRs) is essential for plant immunity. NLRs can directly interact with effectors or indirectly detect them through host guardees/decoys (HGDs). HGDs undergo various biochemical modifications by effectors, expanding the effector recognition spectrum of NLRs and contributing to robustness of plant immunity. Investigating the diversification of HGDs would provide insights into how they enable NLRs to recognize novel effectors.

Summary: This study reveals the important role of E3 ubiquitin ligases in the pathogenesis of Plasmodiophora brassicae, inhibiting host immunity by degrading host immune-associated cysteine proteases. The secreted E3 ubiquitin ligases from Plasmodiophora brassicae interact with and ubiquitinate host immune-associated cysteine protease RD21A, leading to compromised host immunity and increased susceptibility to the pathogen.

Summary: EDR1 is a negative regulator of resistance, while RAF3/4/5 are homologs of EDR1 in Arabidopsis. The roles of RAF3/4/5 in resistance and their functional link with EDR1 in plant immunity were investigated. Results showed that the edr1 raf3/4/5 quadruple mutant exhibited enhanced resistance compared to edr1, and MPK3/6 kinase activity was more highly activated in edr1 raf3/4/5. Additionally, the enhanced resistance of edr1 raf3/4/5 required SID2, an isochorismate synthase for salicylic acid synthesis. These findings highlight the complex and important role of Raf-like MAPKKKs in plant immunity regulation.

Summary: Plant hormone brassinosteroids (BRs) play crucial roles in plant immunity by regulating the expression of callose synthase gene GLUCAN SYNTHASE-LIKE 8 (GSL8) and promoting callose accumulation, which enhances the resistance to pathogen infection. The molecular mechanism and key components of BR-induced pathogen resistance remain to be fully elucidated.

Summary: Gram-negative bacterial plant pathogens use effectors to manipulate plant metabolism and evade host surveillance. In this study, the effectors AvrRpm1Pma and AvrRpm2Psa from Pseudomonas syringae were found to activate the plant resistance protein RPM1 by modifying the RIN4 protein. The activation of RPM1 was triggered by distinct modifications of RIN4 by different pathogen effectors.

Summary: This study reveals that ETI-mediating NLRs and NLR signaling components NDR1 and EDS1 can promote the salicylic acid sector of defense downstream of MPK3 activity. It also demonstrates that both sustained and transient MPK3/6 activities positively control the expression of several NLR genes. The findings highlight the intricate interplay of PTI and ETI pathways.

Summary: The helper NLRs Nrc2 and Nrc3 play important roles in the immunity of tomato plants to the bacterial pathogen Pseudomonas syringae pv. tomato (Pst) mediated by the sensor NLR Prf and the Pto kinase. They act additively with Prf/Pto and upstream of MAPK signaling. However, they are not required for programmed cell death triggered by another sensor NLR mediating Pst resistance.

Summary: Pseudomonas syringae pv. actinidiae (Psa) causes bacterial canker, a devastating disease threatening the Actinidia fruit industry. In the study, the researchers identified a protein called ZAR1 that can recognize HopZ5 and trigger cell death, suggesting a potential non-host resistance mechanism against Psa. They also found that ZAR1 and RPM1 proteins have specific requirements for conferring resistance to different strains of P. syringae carrying HopZ5. Additionally, the study revealed the involvement of SOBER1 in regulating these resistance responses.

Summary: This study demonstrates that the maintenance of leaf microbiota homeostasis in Arabidopsis thaliana plants requires the involvement of the NADPH oxidase RBOHD, as its absence leads to enrichment of opportunistic pathogens. The composition of plant microbiota is greatly influenced by the plant immune system, highlighting the importance of both immune system and microbial community in maintaining plant health.

Summary: In a liquid crystal emulsion, chemically different guest phases reside in the topological disclinations of the host phase. These disclinations act as effective capillaries, leading to various meniscus and droplet phenomena. This demonstrates that anisotropic forces associated with liquid crystal molecules play a critical role in determining the shape and properties of a phase boundary.

Summary: Phytohormone signalling pathways play an important role in plant defence against pathogens. This study revealed that a pepper NLR protein Tsw interacts with a viral effector NSs to inhibit phytohormone receptor function, promoting virulence. Moreover, the plant has evolved a counter-virulence strategy by recognizing the interference of phytohormone signalling through a NLR protein with a structure resembling phytohormone receptors.

Summary: The aboveground parts of terrestrial plants are inhabited by a variety of microbes, collectively known as the phyllosphere microbiota. Research on individual phyllosphere microbes has provided foundational knowledge about their adaptation to the phyllosphere environment and their role in biological control against pathogens. Recent studies have expanded our understanding of the phyllosphere microbiota across plant taxa and how plants regulate and respond to it, providing insights into improving agriculturally relevant traits of crop plants through plant and microbiota-based technologies.
