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.
