Glutamate triggers long-distance, calcium-based plant defense signaling.
Plants rely on rapid systemic communication to coordinate defense responses against local threats. Here, we demonstrate that extracellular glutamate released upon wounding functions as a damage-associated molecular pattern (DAMP) to trigger long-distance calcium-based defense signaling in Arabidopsis thaliana. Using genetically encoded Ca2+ reporters and pharmacological blockers, we show that glutamate perception by specific GLUTAMATE RECEPTOR-LIKE (GLR) channels initiates a propagating Ca2+ wave that traverses vascular bundles, leading to activation of downstream MAPK cascades and transcriptional reprogramming in distal leaves. Loss-of-function mutants in GLR3.3 and GLR3.6 exhibit attenuated systemic Ca2+ elevations and reduced expression of defense genes, confirming the essential role of these channels in glutamate-triggered signaling. Our results reveal a molecular framework by which plants convert wound-derived glutamate into a rapid calcium signal to prime distal tissues for enhanced immunity.
Stem Cell Health and Tissue Regeneration in Microgravity
Microgravity presents a unique environment that profoundly impacts stem cell viability, proliferation, and differentiation potential, posing both challenges and opportunities for tissue regeneration in spaceflight. In this study, human mesenchymal stem cells (hMSCs) were cultured aboard the International Space Station for 21 days to assess changes in self-renewal capacity, lineage commitment, and paracrine signaling compared to ground controls. Results demonstrate significant downregulation of osteogenic and myogenic differentiation markers, altered Wnt/β-catenin signaling, and enhanced secretion of growth factors such as VEGF and IGF-1 in microgravity. Post-flight recovery assays reveal partial restoration of stem cell function, highlighting the resilience and adaptability of hMSCs. These findings elucidate molecular mechanisms underlying stem cell behavior in space and inform the development of targeted tissue regeneration strategies for long-duration missions and terrestrial regenerative medicine.
Metagenomic interrogation of urban Superfund site reveals antimicrobial resistance reservoir and bioremediation potential.
Urban Superfund sites represent hotspots of microbial communities exposed to high levels of chemical contamination and antibiotic residues. Here, we applied deep shotgun metagenomic sequencing to soil samples collected from an urban Superfund location to characterize the resident microbiome, antimicrobial resistance (AMR) gene reservoirs, and the genetic potential for contaminant degradation. Bioinformatic assembly recovered multiple metagenome-assembled genomes (MAGs) harboring diverse resistance determinants against beta-lactams, tetracyclines, and heavy metals, indicating a robust AMR reservoir in situ. Functional annotation revealed enriched pathways for hydrocarbon and chlorinated solvent degradation, including monooxygenases, dioxygenases, and reductive dehalogenases. Laboratory microcosm assays confirmed the capacity of native consortia to degrade polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) under aerobic conditions. These findings underscore the dual role of contaminated soils as reservoirs of AMR genes and as sources of bioremediation potential, providing a foundation for targeted remediation strategies that mitigate resistance spread while enhancing pollutant degradation.
