SOSEKI polarity proteins are mechanoresponsive integrators linking growth and tissue mechanics during lateral root formation. Their polarity marks growth boundaries and reorganises in response to mechanical alterations —reshaping how we think about axis formation.

How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. @treebiocoe.bsky.social @erc.europa.eu 1/x 🧵 www.nature.com/articles/s41...
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.
