Summary: The study demonstrates that fitness mutants with moderate levels of salicylic acid accumulation and SA signaling activated show restricted pathogen infection and higher seed set. NPR1 is found to be essential in these mutants for SA storage and defense activation, while the FITNESS transcriptional network includes defense-related transcription factors and JA related genes, modulating JA-related responses during pathogen attack.

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: Plant responses to pathogens involve complex signaling processes, with hydrogen cyanide (HCN) playing a role in inducing resistance. The beta-cyanoalanine synthase CAS-C1 is crucial in detoxifying HCN and its mutation affects plant resistance mechanisms. The study also suggests new mechanisms for the modulation of the immune response by HCN in plants.

Summary: Plants are able to sense and respond to molecular signals associated with the presence of pathogens and their virulence factors. This study investigates the potential role of a mechanosensitive ion channel, MscS-like (MSL)10, in defense against the bacterial pathogen Pseudomonas syringae in Arabidopsis thaliana. The results show that MSL10 modulates pathogen responses and suggests that mechanical signals may be utilized by plants for pathogen perception.

Summary: The research provides an in planta characterization and functional analysis of the three-member gene/protein MDL family in Arabidopsis thaliana. The study shows that MDL1, MDL2, and MDL3 form homo-oligomers and hetero-oligomers, and play a role in regulating both developmental and immune-related processes in plants. The findings expand the comparative cross-kingdom analysis of MIF/MDL signaling in human and plant systems.

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: 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: 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: 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: 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: This study identified Khib modification proteome in Arabidopsis siliques under salt stress, revealing a significant downregulation trend of Khib modification. The differentially regulated proteins were found to participate mainly in glycolysis/gluconeogenesis and endocytosis pathways. KEGG pathway enrichment analysis showed an enrichment of Khib-modified proteins related to energy metabolism pathways. This study provides insights into the regulatory mechanisms of Khib during plant response to salt stress.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
