DNA (de)methylation and plant immune memory 🌱🧠 Postdoctoral researcher, Ton Lab, University of Sheffield

New Article: "Occupancy-based mechanism is the chief mode of ROS1 function in preventing DNA hypermethylation" rdcu.be/fb7P0 ROS1 mediates DNA demethylation via a passive mechanism; ROS1 occupancy marks & regulates accessible chromatin, highlighting its diverse roles.

Interested in plant development and/or cell walls? We (Sam Amsbury, Andrew Fleming and I) have three PhD positions at the University of Sheffield open for applications until 7th January. We offer a friendly, jointly-run lab, great facilities, an affordable city and proximity to the Peak District!

Details of the three PhD projects on offer: Primed for Protection: Cell Wall Modifications in Plant Defense and Long-Term Immunity, Engineering Stomata: How Shape Informs Function: and Signalling Complexes and Cell Wall Changes during Plant Reproduction

Very excited to finally share the main findings from my PhD, now out as a preprint! We developed an epigenetic system to understand how plants remember and forget past infections - a phenomenon known as immune memory 🌱🧬🧠 Highlights below! 1/9 www.biorxiv.org/content/10.1...

From recall to reset: the role of DNA (de)methylation in modulating plant immune memory

Epigenetic reprogramming is increasingly recognised as a driver of plant immune memory, yet its molecular basis remains poorly understood. Using a chemically inducible transgene in Arabidopsis, we tra...

Plants remember stress! The PlantMemo project, led by ‪@jurriaanton.bsky.social‬, has secured an ERC Advanced Grant for an exciting project decoding how stress “memories” boost plant resilience—paving the way for hardier crops. 🔗 www.sheffield.ac.uk/biosciences/... #PlantScience #PlantImmunity #ERC

New research aims to unlock stressful plant memories

New research led by Prof Jurriaan Ton aims to uncover how plants adapt and survive in challenging environments with the ultimate goal to create more resilient crops.

I'm thrilled to share that our study is now published in Cell: Extensive N4 cytosine methylation is essential for Marchantia sperm function. www.cell.com/cell/fulltex... This paper confirms our 4mC discovery in Marchantia sperm and takes it much further. A thread: 0/13

Extensive N4 cytosine methylation is essential for Marchantia sperm function

Global N4 cytosine methylation in Marchantia polymorpha sperm regulates gene expression and promotes sperm fertility.
