Scientists map microbiome hidden deep inside tree trunks
Researchers find trillions of bacteria in tree trunks, including methane producers.
Why it matters
- Discovering a new ecosystem inside trees.
- Potential impact on greenhouse gas emissions calculations.
By the numbers
- About 150 trees analyzed.
- 16 species studied.
- 1 trillion bacteria per mature tree.
The big picture
- Microbes inside trees are different from those in the rest of the forest.
- Anaerobic bacteria found in heartwood resemble those in wetlands.
- Evolutionarily close trees have similar microbiomes.
What they're saying
- Co-lead author Jonathan Gewirtzman notes the unique microbial community inside trees.
- Plant microbiologist Sharon Lafferty Doty highlights the importance of studying natural plant-microbe partnerships for agricultural health.
Caveats
- The study is comprehensive but may not cover all tree species.
- The impact on greenhouse gas emissions needs further study.
What’s next
- Further research on the role of these microbes in tree health and function.
- Exploration of how these findings might affect greenhouse gas emissions calculations.
