Plants monitor the integrity of their barrier by sensing gas diffusion - Nature
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.
www.nature.com
Plants can sense when their barrier is injured—and repair it! 🌱
This stunning work, led by Hiroyuki Iida, shows that wounding is sensed through the diffusion of two gases: ethylene and oxygen.
I had the pleasure of contributing and see this project grow.

Tissue-specific regulation of a sugar transporter mediates both resistance and tolerance responses to attack from a leafminer in potato
Potato plants differentially regulate SWEET11 in sink and source leaves, which mediates two distinct responses to herbivory.

A great overview, very close to what we do. For years we’ve known the cell wall speaks. At the @cellwalldynamics.com lab we’re now decoding its vocabulary. Each chemical and mechanical cue carries meaning, helping us understand –and soon guide– how plants grow and adapt.
Scientists long thought the plant cell wall to be dead, but it's an active, even chatty participant in cellular growth, reproduction and responses to infection
