So, we all know that VIPP1 (the Very Important Protein in Plants) is the "photosynthetic ESCRT-III", required for the biogenesis and maintenance of light-harvesting thylakoids. But what about ESCRT-II, you say? ...Meet VIA1! Congrats @mayankdu.bsky.social on your lab's first paper! #PlantScience 🧪 🌾
Hot off the press, first PI paper 🎉. Reporting a novel protein (VIA1) involved in thylakoid membrane biogenesis. VIA1 (similar to ESCRT-II) and bind to chloroplast ESCRT-III (VIPP1). Showing a direct role of VIPP1 in thylakoid biogenesis.

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.
