This is such a cool principle! I had never thought about it, but it makes so much sense.

🌱🧬 Plants sense barrier injury through gas diffusion. Ethylene leaks out, oxygen enters. This triggers periderm regeneration. Fixed barrier restores original gas levels.

A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.
