It was wonderful meeting Bala and the kids recently in the UAE. Some memories refreshed, some stories shared, and plenty of laughter over a dinner table. Moments like these remind you how special friendships are. 🙂

Fungus-farming termites can protect their crop by confining weeds with fungistatic soil boluses The symbiotic agriculture of fungus-farming termites can collapse if they fail to prevent invading weeds. Previous studies suggest a role for symbiotic fungistatic microbes in bringing about weed cont...

When harmful fungi invade their carefully cultivated crops, fungus-farming termites fight back with the precision of skilled gardeners, a new Science study reveals, smothering them in soil clumps enriched with microbial allies that inhibit fungal growth. https://scim.ag/4nsAqCu

Synthetic communities of maize root bacteria interact and redirect benzoxazinoid metabolization Plant roots are colonized by diverse microbial communities. These communities are shaped by root exudates, including plant-specialized metabolites. Benzoxazinoids are such secreted compounds of maize. Individual microbes differ in their ability to tolerate and metabolize antimicrobial benzoxazinoids. To investigate how these traits combine in a community, we designed two synthetic communities of maize root bacteria that share six common strains and differ in their ability to metabolize benzoxazinoids based on the seventh strain. We exposed both communities to the benzoxazinoid MBOA (6-methoxybenzoxazolin-2(3H)-one) in vitro and found that the metabolizing community did not degrade MBOA to its aminophenoxazinone, as observed for individual strains, but, as a community, they formed the corresponding acetamide. MBOA shaped the differential compositions of both communities and increased the fraction of MBOA-tolerant strains. The benzoxazinoid-metabolizing community showed a higher tolerance to MBOA and was able to utilize MBOA as their sole carbon source for growth. Hence, bacterial interaction results in alternative benzoxazinoid metabolization and increases community performance in the presence of these antimicrobial compounds. Future work is needed to uncover the genetics of this metabolic interaction and ecological consequences for the bacterial community and the host plant.

Very nice work from @kschlaeppi.bsky.social and co-workers. It illustrates once again the power and relevance of looking at communities in addition to individual strains > Synthetic communities of maize root bacteria interact and redirect benzoxazinoid metabolization

A bittersweet day in the lab. One experiment crashed and burned, while another produced textbook-perfect results. That's science: full of setbacks and surprises. Despite a rough start, I am ending the day on a high note!

Yeah. I know how different soils may have drastic effects on soil/rhizo microbiome. But my plants are growing in one common soil & we assumed different cultivars to harbor different microbes over time. Many pots so not possible to sequence them all😟.
"It depends" makes life harder than easier.😂😂😂

I have a question: many research lines show cultivar specific microbial communities in soil. Is it always important to varify this with your own samples or just assuming it be the case would be alright? Not always possible to sequence them.
