The gut #microbiome actively monitors dietary intake and, in combination with a low-protein diet, can produce molecular signals that convert energy-storing white fat cells into energy-burning beige fat cells.

Nitrous oxide, a common #greenhouse gas and byproduct of #agricultural fertilizer use, actively shapes microbial communities at the #plant root by exhibiting toxicity toward specific soil bacteria, contradicting the long-held assumption that the gas does not interact with rhizosphere organisms.

Nitrous oxide, a product of fertilizer use, may harm some soil bacteria

While some N2O is produced naturally at the plant root, agricultural practices can increase its levels, to the detriment of some microbes that support

In new research, Yu-Ying Phoebe Hsieh , Ian O’Keefe, Ajai Dandekar, Harmit Malik &co reveal how magnesium sequestration by C. albicans enables P. aeruginosa to evolve much higher levels of resistance to colistin (a last-resort #antibiotic).

Magnesium depletion by Candida albicans unleashes two unusual modes of colistin resistance in Pseudomonas aeruginosa with different fitness costs

Bacterial resistance to the vital last-resort antibiotic colistin is an increasing challenge. This study shows that magnesium sequestration by C. albicans enables P. aeruginosa to evolve much higher levels of colistin resistance via changes in lipid A biosynthesis-modification pathways and a magnesium transporter.

Mycorrhizal fungi colonize plant roots to form a bidirectional symbiotic network, efficiently extracting essential soil nutrients and exchanging them for carbohydrates produced by the plant via photosynthesis.

🌿 New strain in the DSMZ collection: Herbivorax alkaliphila sp. nov.
This bacterium was isolated from a salt lake and can break down plant cellulose even in salty conditions – only the second known bacterium with this ability described from such habitats. It sheds light on how microbes help recycle plant material in extreme environments.

A regulatory network promotes apoplastic alkalinization to prime #plant #immunity in tissues distal to site of infection.

Pathogen‑induced apoplastic alkalinization and phytocytokines interact to prime distal immune defenses.

Need advice from #bioinformatics #microbiology folks here.

PE short reads from a collaborator field isolated bacteria. Got it down to species level comparing against globdb&gtdb entries on reads and initial asm. Likely about 35x coverage?

Very fragmented asm, can't get rrn sites to assemble - only partial 16S&23S.

Reads only map to about 80~85% of genomes from database matching species.

My gut says something else not picked up by the DBs is in the reads.

Thoughts?
