The EGY1-SGR1 module controls chloroplast development and senescence by modulating photosynthetic functions
The chloroplast plays essential roles not only in production of biochemical energy and metabolism, but also in plant development, including senescence. We describe a mutant with an unusual progression...

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.
