New paper - led by Isabella Østerlund

Rho-GTPase overexpression can impact the development of cell shape and airspace structure in Arabidopsis.

These genetic changes can also reduce photosynthesis, due to lower mesophyll conductance

Rho GTPase overexpression impacts leaf internal architecture and mesophyll conductance in Arabidopsis

Leaves are built from multiple cell types and are structured to enable the conversion of carbon dioxide and water into sugars in the process of photosynthesis. Understanding how cell architecture im.....

The bracken ferns are perfect right now. Still structurally intact but a delicious copper colour. In a few weeks they will be a slimy black heap of muck, so I am glad to have this lovely image to remember them by 💚

Great new postdoc fellowship for foundational plant research.
If you’re into genetics and genomics of plant reproductive evolution or adaptive convergence (incl in the cool and charismatic nightshades!) I’d be happy to talk about possible projects!

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 🧪 🌾

Mayank Sharma @mayankdu.bsky.social · 17h

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.

Our article "Guns in Rosettes: The Arabidopsis chemical weapons arsenal" is finally published @plantphys.bsky.social!
You can download the #OpenAccess PDF here:

doi.org/10.1093/plph...

But real connoisseurs of #AntimicrobialCompounds will want to get the vinyl boxset: #PlantScience #PlantImmunity

A vinyl box with six colored vinyl LPs sticking out of its right side. The Title "Guns in Rosettes" is on top, with the subtitle "The Arabidopsis chemical weapons arsenal" just below. Then there is an Arabidopsis plant with machine guns sticking out. Below is the statement "6-LP LIMITED EDITION COLORED VINYL BOX SET"

The back cover of the vinyl box set showing the tracklist:
1. Methionine-derived compounds
Aliphatic GSLs
2. Tryptophan-derived compounds (trptonites)
Indolic GSLs
Camalexin
Hycanite (4-OH-ICN)
3. Phenylalanine-derived compounds (phenylpropanoids)
Benzenic GSLs
Coumarins
Hydroxycinnamates
Flavonoids
4. Terpenoids
(E)-β-caryophyllene
α- and β-pinene
Thalianin, arabidin, and DMNT

And the statement "Recorded live in front of an audience in 2025"

Let’s stare into the far red 🏮. A stunning tour-de-force of high-resolution #CryoEM by Gio, Bill, & company reveals how the machinery of photosynthesis redshifts itself so cyanobacteria can live on far red light, deep in the cracks of rocks or under microbial mats. #PlantScience 🧪 🧶🧬 🌾 🔬 🌍

Have you ever looked at the night sky and wondered if there’s a chlorophyll f in the reaction centre of Photosystem I from far-red light adapted cyanobacteria? 🦠

Well, we did (don’t judge) and the work that followed is now out as a First Release in @science.org
