Very happy that my PhD student can grow such happy plants! It's a simple thing that is very underappreciated and very important.
A tray of 14 happy Arabidopsis plants at the rosette stage in 7cm pots. Black covers preventing the compost from being visible.

The project is fully funded, but for for UK students only (Apologies to international applicants, there is no funding for visas or international fees).

I'm happy to be emailed for more details, but all applications should be made via the web portal here: www.findaphd.com/phds/project...

Tutored by me and Julie Gray, you'll use cutting-edge imaging and treatment chambers to monitor how stomatal aperture changes with #ABA under controlled environmental conditions. This will unlock new aspects of #stomata and #drought stress signalling!
A custom imaging chamber containing an Arabidopsis leaf. The chamber is below a microscope lens with an LED lamp, and the chamber is connected to a tube.

The Rowe lab is recruiting a #PlantScience PhD student for 2025! You'll use our new ABACUS FRET biosensors to map the leaf #AbscisicAcid accumulations at low humidity in Arabidopsis, wheat and rice to understand how ABA regulates stomatal dynamics. #PhDposition

A grey coloured Arabidopsis leaf epidermis, with black cell walls. Each cells has a colourful blobs - a nuclear localised fluorescent ABA sensor, with warm colours indicating high concentrations, and cooler colours indicating lower concentrations.

Today is awesome summer student Harry Lever's last day in the lab. He built awesome gas mixers that easily control CO2 and relative humidity, whilst measuring the changes in real time. AND he hooked them up to awesome leaf treatment chambers! I'm so impressed. #PlantScience #Ecophysiology #arduino

Just finished folding #PlantScience #zines for GPSEP's #Rootstock tomorrow at @slcuplants.bsky.social. Look out for #PlantSciZines by @sainikumud.bsky.social , Sarah and I!
A box full of identical black and white zines, with several layed out in front of it. The Zines have a rosette plant on the front and the 'Thirsty boiz' written in faux grafitti font.

Feeling like a proud Dr Frankenstein, having successfully grafted my first Arabidopsis plants! Thank you Dongwhi Ko for the help!

Rice really does have very pretty cells #plantscience
Rice epidermis, with cell walls in cyan, nuclei in green and chloroplasts in magenta. Image shows a series of squiggly epidermal cells separating 4-cell stomatal complexes
