I'm thrilled to see our recent paper out in @dev-journal.bsky.social 🎉
Here we look into the transition from cell division to differentiation in the late stomatal lineage and identify regulators of guard cell morphology and function

Did you know that stem cells have unusually large transcription clusters, which disappear upon differentiation? Yes? You paid attention in 2018!
In 2026, we show you that this process proceeds via massive, global shifts in transcriptional control.

Happy to share our newest preprint. We developed guidelines and analysis workflows for FLIM Imaging in plants. Multiplexing with spectrally overlapping fluorophores in plants is now possible. Have a look. Any feedback is more than welcome.

Fast growth comes at a cost: Fast-growing Eucalyptus are less drought-resistant, revealing a clear growth–survival trade-off.
