Summary: It has been shown that moderate drought stress increases the susceptibility of Arabidopsis thaliana to bacterial pathogens, and that drought and bacterial stress antagonistically modulate a large set of genes through the SA and ABA signaling networks. Under combined stress, drought downregulates the induction of SA production through the ABA pathway, impacting plant defense against bacterial pathogens.

Summary: Lyso-phosphatidylethanolamine (LPE) promotes signaling and biosynthesis gene expression of the defensive hormone salicylic acid (SA) in plants, enhances oxidative stress and reactive oxygen species (ROS) production, and improves plant basal immunity. Moreover, LPE increases plant resistance against hemibiotrophic pathogens.

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: Activation of the FLS2 receptor suppresses both early infection stages' virulence and long-term growth of PstDC3000 by promoting glutamine and serine buildup in the leaf apoplast. MAMP perception in Arabidopsis induces the accumulation of free amino acids in a SA-dependent manner. Glutamine and Serine, when co-infiltrated, suppress virulence gene expression and robust infections in susceptible plants.

Summary: This study developed a strategy to increase the efficiency of plant transformation by engineering Agrobacterium and suppressing host defense responses. The results showed that the transformation efficiency of wheat, alfalfa and switchgrass increased by 250%-400% using the engineered Agrobacterium.

Summary: OMVs from Pseudomonas syringae and P. fluorescens can activate plant immune responses to protect against bacterial and oomycete pathogens. The immunomodulatory activity of OMVs from these species varies in sensitivity to biochemical stressors, reflecting differences in OMV content. Furthermore, plant responses mediated by OMVs are distinct from those triggered by other bacterial epitopes or effector molecules.

Summary: Calcium (Ca2+) signaling is a crucial universal information code in plants, which is decoded into specific adaptive responses by different Ca2+ sensing proteins. Although the molecular details of these processes are still largely unknown, studying the kinetics of different proteins and their interactions with targets can provide insights into Ca2+ decoding and target binding mechanisms controlled by Ca2+ in plants.

Summary: Plants have cell-surface and intracellular receptors to recognize pathogen effectors. These receptors, along with their coreceptors, form networks to mediate downstream immune responses. The cell-surface and intracellular immune systems are interdependent and function synergistically to provide robust resistance against pathogens.

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: 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: Stomatal defences, mediated by apoplastic ROS, are vital for plants to prevent pathogen entry. This study sheds light on the role of NADPH oxidase RBOHF in the interplay between apoplastic and cytosolic ROS dynamics during stomatal immune response. Surprisingly, the rbohF mutant showed unexpected over-oxidation of the H2O2 sensor roGFP2-Orp1, while being impaired in PAMP-triggered stomatal closure and apoplastic alkalinisation.

Summary: This study found that enzymatic hydrolysate of fucoidan (FEH), derived from Sargassum hemiphyllum, can trigger various immune responses in plants, including ROS production, MAPK activation, gene expression reprogramming, callose deposition, stomatal closure, and plant resistance to Pseudomonas syringae pv. tomato (Pst) DC3000. Therefore, FEH has the potential to be used as a non-microbial elicitor to protect plants from pathogen infection in agricultural practices.

Summary: This study observed the presence of bacterial biofilm-like aggregates in plants and found that they contribute to the success of pathogenic bacteria's reproduction. The study also revealed the crucial role of plant-produced salicylic acid in suppressing the formation of bacterial biofilm-like aggregates.

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.
