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.

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.

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...

Fig. 2 legend (shortened): Localization of poly(A) RNA and stress granules in resin sections of meristematic cells of lupin roots in response to hypoxia. Poly(A) RNA was detected by fluorescence in situ hybridization (FISH; red) and stress granules (SGs) were detected by immunofluorescence (IF; green) of Poly(A) Binding Protein 2 (PAB2). Cells after (A–C) 6 h and (D–F) 15 h of hypoxia. Merged images of the FISH and IF signals together with DAPI staining are shown. Arrowheads indicate SGs. The scale bar is 5 µm. (G) Ultrastructure of the bi-zonal form of the SGs; r, ring of coiled, dense fibers; c, central brighter area; er, endoplasmatic reticulum. Scale bar is 3 µm. (H) Stochastic optical reconstruction microscopy (STORM) analysis. The dots represent individual poly(A) RNA molecules that were detected during the acquisition and are color-coded by depth.
