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.....

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

New pre-print from the team!

The manuscript is @emma-raven.bsky.social's PhD work showing that whether a leaf is a carbon sink or a carbon source influences how they execute immune responses.

Have a read!

How do cells communicate when it’s hot? (FAULKNER_J26DTP) | Doctoral Training Partnership Plant cells are connected to their neighbours via ‘tubes’ called plasmodesmata, creating an interconnected cytoplasm that joins cells within and between tissues and organs.

We have a project available for 2026 NRP Doctoral Training Partnership entry (i.e. PhD studentship opportunity!)

How do cells communicate when it's hot?

Don't know? Me either! Come work with us @johninnescentre.bsky.social and figure it out

Pleased to see our perspective on the C3 model of photosynthesis published. It was fun revisiting the science behind it.

Nobel Prize in Physiology or Medicine 2012 The Nobel Prize in Physiology or Medicine 2012 was awarded jointly to Sir John B. Gurdon and Shinya Yamanaka "for the discovery that mature cells can be reprogrammed to become pluripotent"

Honouring the life of Sir John Gurdon, who died earlier this week: awarded the Nobel Laureate in Physiology or Medicine for seminal work carried out in Oxford Zoology (now @biology.ox.ac.uk) showing that mature cells could be reprogrammed to become pluripotent.

Interested in a 4 year fully funded PhD, based at Lancaster @lancasteruni.bsky.social and working with other Universities via NorthWestBio? Does that interest include photosynthesis and/or plant engineering?
Well, step right up! Open to UK & non-UK people, 2026 projects include 3 I am a part of:

@marjorielundgren.bsky.social has a project in partnership with Nick Birse at Queen's University Belfast, looking into climate change impacts on nutritional quality in different crops, and how this could be linked to photosynthetic type. www.gla.ac.uk/postgraduate...

Fantastic oppurtunity for a PhD project centred around the activity and regulation of my personal favourite enzyme Rubisco, with an awesome supervisor @ecarmosilva.bsky.social, and supported by the Gatsby Foundation. @sci-tech-lancaster.bsky.social @lancasteruni.bsky.social

Thank you very much! 😊

Dual-cycle CO2 fixation enhances growth and lipid synthesis in Arabidopsis thaliana Carbon fixation through the Calvin-Benson-Bassham (CBB) cycle accounts for the majority of carbon dioxide (CO2) uptake from the atmosphere. The CBB cycle generates C3 carbohydrates but is inefficient ...

Introducing a new metabolic cycle - the McG cycle - into Arabidopsis to convert 3PG to acetyl coA. This then feeds into endogenous lipid synthesis increasing plant lipids, seed yield and biomass. Out this week in @science.org!

Congratulations, Isabel!

Congratulations, Sebastian!

Thank you, Pingtao!

Super proud of @zoeweeks.bsky.social and the rest of the team for this work. We were honoured to be selected as a research highlight - see our interview here: journals.biologists.com/dev/article/...

Dr Tina Schreier awarded ERC Starting Grant

@tinaschreier.bsky.social has been awarded an @erc.europa.eu Starting Grant for research into the cell biology of C4 photosynthesis 🌱

Tina’s project will explore the cell biology that leads to the formation of specialised bundle sheath cells in C4 plants 👇

Congrats, Vinay!! Super excited for you

Congratulations, Clémence!

We will explore how the unique organelle placement and increased cell-to-cell connectivity are formed in these cells, and how these features contribute to the incredible photosynthetic efficiency of C4 plants!

I'm beyond thrilled to receive an ERC Starting grant for our CELL4 project, to dive into the fascinating cell biology of bundle sheath cells in the C4 grass Sorghum!! 🌱 @erc.europa.eu @biology.ox.ac.uk

Congratulations @jmhibberd.bsky.social on being elected to EMBO!

A host organelle integrates stolen chloroplasts for animal photosynthesis Sea slugs steal foreign chloroplasts and store them in specialized organelles that facilitate photosynthesis and eventual digestion to mediate starvation resistance.

Remarkable paper explaining how sea slugs maintain chloroplasts obtained by kleptoplasty active for many month & eventually digest them for resources www.cell.com/cell/fulltex...

Congratulations, Julian - so very well deserved!! 🥳
