Very much looking forward to hearing and seeing exciting research and to interacting with reseachers at #2025ISMPMI. Happy also to answer any questions about publishing in Nature and sister journals.

Injured plants use gaseous cues to initiate repair of their outer layers The periderm layers of plants form an outer protective barrier. If the periderm is broken, movement of the gases ethylene and oxygen triggers a healing process.

How do plants notice loss of structural barriers (e.g. the periderm, which prevents water loss and pathogen infection) to regenerate them? Work @nature shows that plants sense damage to barrier integrity from diffusion of gases such as ethylene and oxygen. shorturl.at/FIhJ8
