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: The rhizosphere is a soil-plant interface where bacterial and fungal species colonize and provide growth-promoting and adaptive benefits. Plant-bacteria relationships rely on the perception of volatile organic compounds (VOCs), phytohormones, and bacterial quorum sensing signals. Beneficial Trichoderma fungi emit active VOCs that contribute to plant morphogenesis and affect their colonization on roots. Recent findings have shed light on how compounds from beneficial bacteria and fungi impact root architecture and the signaling events mediating microbial recognition.

Summary: The proper subcellular localization of defense factors, such as AZI1, is important for the plant immune system. AZI1 is essential for systemic resistance and utilizes a bipartite N-terminal signature for plastid targeting, possibly related to defense responses. Kinases MPK3 and MPK6 are also involved in promoting the accumulation of AZI1 at plastids during priming induction.

Summary: Phosphorylation of Ser318 is crucial for the activation of CPK28 in immune homeostasis and stem elongation, providing protection against immune response initiation in the absence of infection. In contrast, Ser318 phosphorylation is not necessary for stem elongation, indicating pathway-specific requirements for phosphorylation-based Ca2+-sensitivity priming. This research also suggests a potential biotechnological application in enhancing resistance to microbial pathogens without affecting yield through conserved Ser318 phosphorylation in related group IV CDPKs.

Summary: This study demonstrates that bacterial virulence factors can modulate plant actin assembly by regulating the clustering and nucleation activity of plant formin on the plasma membrane. This central mechanism plays a crucial role in rapid actin remodeling during interactions between plants and bacteria.

Summary: This study examined the plant protective and immunization effects of autoclaved spores of Verticillium dahliae against the pathogen. The results showed that the application of autoclaved spores enhanced protection against Verticillium dahliae in eggplants and Arabidopsis, and the upregulation of defense related genes was observed in Arabidopsis treated with autoclaved spores. The involvement of the chitin receptor CERK1 in Arabidopsis immunization against Verticillium dahliae using autoclaved spores was also revealed.

Summary: Plant CNGCs play a crucial role in cytosolic Ca2+ influx for immune defense and thermosensing. Physically interacting CNGCs (CNGC2, CNGC4, and CNGC6) may form a multimeric channel complex involved in immune signaling, while CNGC12 does not interact with other CNGCs. CNGC2, CNGC4, and CNGC6 mutants showed impaired response to the elicitor peptide Pep3, whereas all four CNGC mutants exhibited thermotolerance.

Summary: Microbial and plant cell walls are recognized by plant immune system to trigger immune responses through plant pattern recognition receptors (PRRs). A computational screening method for predicting potential ECD-PRR/glycan interactions was developed and validated using Arabidopsis LysM-PRR members CERK1 and LYK4, providing insights into protein-glycan interactions and immune responses activated by glycoligands.

Summary: The study explored the interaction between plants and beneficial bacteria, revealing that activation of the plant immune system is crucial for efficient bacterial colonization and auxin secretion. A feedback loop was established where bacterial colonization triggers an immune reaction and production of reactive oxygen species, which in turn stimulates auxin production by the bacteria. This mutual feedback loop promotes the fitness of both partners.

Summary: Autophagy is a crucial pathway for degrading excess proteins and organelles, with ATGs playing a key role in its formation. Of the 35 identified ATGs in Arabidopsis, 17 are involved in plant pathogen resistance. NPR1, a transcription coactivator, regulates plant immunity and salicylic acid-responsive genes.

Summary: This study reveals the important role of the NPR gene family in the SA signaling pathway in the model monocot Brachypodium distachyon. BdNPR2 positively regulates the transcription of PR1 mediated by BdTGA1 through SA binding, while BdNPR1 functions as a suppressor of BdNPR2/BdTGA1-mediated transcription of PR1.

Summary: Plants defend against folivores by activating signaling cascade networks to respond to folivore-derived elicitors. In Arabidopsis, the protein kinase HAK1 mediates the upregulation of defense genes in response to polysaccharide elicitors from Spodoptera litura larvae through the cytoplasmic kinase PBL27. This study investigated the involvement of other protein kinases, including CPKs and CRKs, in the intracellular signaling network for anti-herbivore responses. The findings suggest that CRK2, in addition to CRK3, interacts with PBL27 to regulate the transcriptional regulation of PDF1.2, a defense gene against S. litura larvae.
