Development of an Engineered Bacterial Endophyte: Promoting Plant Growth Through Pyrroloquinoline Quinone (PQQ) Synthesis [PDF]

Microorganisms
Endophytic bacteria are a group of microorganisms that can intercellularly colonize plant hosts without causing apparent damage or disease. Our previous works found that a pyrroloquinoline quinone (PQQ)-producing endophyte could promote plant growth and ...

Pyrroloquinoline Quinone Attenuates Traumatic Brain Injury-Induced Secondary Damage by Activating PINK1/Parkin-Mediated Mitophagy and Suppressing ASS1/CPS1-Driven Arginine Biosynthesis. [PDF]

CNS Neurosci Ther
Pyrroloquinoline quinone (PQQ) attenuates traumatic brain injury in mice. Multi‐omics integration and molecular docking reveal that PQQ activates PINK1/Parkin‐mediated mitophagy to restore mitochondrial homeostasis while suppressing ASS1/CPS1‐driven arginine biosynthesis to dampen neuroinflammation, identifying a dual‐axis therapeutic mechanism for TBI.

Genome-Resolved Insights Into Phosphate-Solubilizing Bacteria From Wild Rice Rhizosphere Reveal Adaptive Strategies for Phosphorus Cycling Under Acid-Saline Stress in the Mekong Delta, Vietnam. [PDF]

Ecol Evol
This study aimed to isolate phosphate‐solubilizing bacteria (PSB) from the rhizosphere of wild rice (Oryza rufipogon) and to investigate their functional traits and genomic basis of adaptation. Genomic analysis of Enterobacter hormaechei GC1.3 identified key genes involved in phosphate mobilization, including gcd and pqqC (organic acid production ...

Source-Independent Enrichment of Light Lanthanides: Microbial Mobilization, Selective Uptake, and Intracellular Storage. [PDF]

Environ Microbiol
Only light lanthanides facilitate lanthanide‐dependent methylotrophy. In Beijerinckiaceae bacterium RH AL1, light lanthanides are enriched from diverse sources, including poorly soluble minerals, through a multilayered process involving mobilisation, selective uptake, and intracellular periplasmic storage.
