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.....

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!

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

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.

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

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:

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

Lancaster Plant Biology @lancasterplantbio.bsky.social · 12d

Another #PhD project available for applications in #photosynthesis with @ecarmosilva.bsky.social @sci-tech-lancaster.bsky.social looking at ways to improve Rubisco. Details below including how the successful nominee will play a direct role in shaping the project proposal tinyurl.com/2a8szv3y

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!

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 ...
