Ancestral and divergent roles of the Marchantia polymorpha ATAXIA TELANGIECTASIA AND RAD3-RELATED kinase in maintaining genome integrity and clonal fitness (Qian-Qian Li , Huiying Li , Jolien De Moor , et al) doi.org/10.1093/plce... #PlantScience @aspbofficial

Ancestral and divergent roles of the Marchantia polymorpha ATAXIA TELANGIECTASIA AND RAD3-RELATED kinase in maintaining genome integrity and clonal fitness

The Marchantia polymorpha DNA damage checkpoint regulator ATR plays an essential role in maintaining fitness over successive clonal generations.

My postdoc preprint is now online @biorxiv-plants.bsky.social. We established HYDRA, a shoot regeneration assay in Arabidopsis without exogenous hormones, and show that photosynthesis-derived carbon drives regeneration via RBR1 pathway–mediated cell cycle activation. www.biorxiv.org/content/10.6...

Photosynthesis-derived carbon gates cell cycle activation to enable hormone-autonomous shoot regeneration

Shoot regeneration is a powerful model for cell fate reprogramming but how it occurs in nature remains poorly understood because studies in Arabidopsis thaliana conventionally rely on in vitro assays ...

After a long absence, I am (briefly?) returning to Bluesky to publicise our research into identifying the ancestral and divergent functions of the Marchantia polymorpha ATR kinase in the plant DNA response pathway. academic.oup.com/plcell/artic...

For those interested in plant DNA damage response pathways and gene editing: the registration for the upcoming Plant Genome Stability and Change 2026 meeting (26-29 May 2026) is now open @ pgsc2026.hzau.edu.cn/index.php

🌊🔬 The 8th International Diatom Meeting is coming to Ghent! Join top researchers & young scientists at #MLD8 to explore diatom biology, ecology & biotech potential. Network, share ideas & enjoy Belgium’s rich gastronomy. Don’t miss it! Find out more: vibbio.tech/40Gz1Of #Microalgae #DiatomResearch

Thrilled to share our work lead by Di Fino in great collaboration with @Panosmoschou,@Hamann_lab, @GreenMechanobio, @RichardSmithLab published @Dev_Cell: Developmental Cell www.cell.com/developmenta...

Cellular damage triggers mechano-chemical control of cell wall dynamics and patterned cell divisions in plant healing

Di Fino et al. analyzed the biomechanical properties of the cell wall in the Arabidopsis root and found that xylem pole pericyclic cell walls are more flexible than outer cell walls. This flexibility ...

It was great to see Rubén Tenorio Berrio's final PhD defence at PSB/UGent on scRNAseq in the Arabidopsis leaf. It was a privilege to also be a member of his jury. Congratulations Ruben! @psb-vib.bsky.social @deveylderlab.bsky.social

Proud to share our latest work, out in @newphyt.bsky.social, where we use single-cell #microsurgery to investigate the molecular fingerprints of size-dependent sexual maturation in diatoms 🔥 (1/n) nph.onlinelibrary.wiley.com/doi/10.1111/...

At the last team building, I tried to axe down the group size, but I couldn't (they're all sooo good!)!

Specific phosphorylation codes drive different roles of the plant RBR1 protein and highlight a critical role for its domain interacting with LxCxE motif-holding proteins. Data obtained from a crazy number of phosphovariants! www.embopress.org/doi/full/10....
