How Trees Secretly Talk to Each Other in the Forest


Webinar: How Crops Benefit From Robust Soil Microbial Populations

My understanding is that fungi to bacteria ratios increase following the labile organic carbon in the soil because protozoa, fungi and plants being eukaryotes require more carbon for cellular function than the bacteria and archaea that are prokaryotes. Building organic carbon in deficient soils by feeding bacteria, archaea and the plants that supply and cycle that carbon by providing a balanced nutrient profile will therefore increase the fungal ratio up to a point at which plants are then amending more soil organic carbon than they need. Plants are then able to support the higher order carbon organisms like fungi with their excess and in doing so form symbiotic relationships that expand their access to nutrients and climate signaling, and in doing so interconnect ecosystems. But only so long as residues are returned and moisture is maintained for the microbes and fauna to break down those residues, along with living roots that host the symbiotic fungi that form the interconnected ecosystem. Because if the carbon from plants and their residues stops, fungi will take it from the plants themselves to survive and will cause fungal, nematode and other plant diseases.

Fats may limit cell organism size in carbon-rich media


Bacterial cells in carbon-rich media (purple and blue) grow twice as big as those in carbon-poor media (green). New research shows they can grow big, however, only if they can make fats with the carbon.

Fat (lipids) limits how big bacterial cells can be. “If you prevent cells from making fat, they’re smaller, and if you give them extra fat or allow them to make more fat, they get bigger,” said Levin, professor of biology in Arts & Sciences. “Fat makes cells fat.”

“If we hit the cells with an antibiotic that targets fatty-acid synthesis, we really saw a significant drop in cell size” Vadia said.

Also, by turning up FadR, a transcription factor that activates expression of the fatty-acid synthesis genes, the cells got bigger.

“It doesn’t seem to matter what the lipids are, really,” Levin said, “provided you have enough of them. We found we could give the cells oleic acid, a fat found in avocados and olive oil, to supplement diminished fatty-acid synthesis and as long as the added fatty acid got into the membrane, the cells could recover.”
