Opening of the #ISPLORE2025JP welcome dinner with some traditional Japanese food by our president Pierdomenico Perata 🍲🍣

The second day of #ISPLORE2025JP starts with a great overview talk by @theplantlab.bsky.social on hypoxia regulation. Hypoxia is everywhere! #plantscience 🌱🌊

Coming to you live from #ISPLORE2025JP Fresh preprint from my lab showing that leaves progressively oxygenate and how this is important for their morphogenesis.Thanks to our collaborators from @Fra_LicO2si lab. #plantscience

Ethylene signal integration through epigenetic mechanisms in plants Ethylene is an essential phytohormone that controls a plethora of plant developmental and stress responses. Accordingly, ethylene signal generation an…

Happy to see our latest #plantscience review by @aidamaric.bsky.social, @advaitagashe.bsky.social and Johanna onlinr! We describe how epigenetic mechanisms control ethylene signal generation and progression, and how ethylene in turn modulates chromatin.

Drought recovery in plants triggers a cell-state-specific immune activation - Nature Communications Post-drought rehydration triggers a preventive immune response in plants, revealing targets to enhance crop resilience by linking drought stress recovery with improved pathogen resistance.

A single-cell, spatial transcriptomic atlas of the Arabidopsis life cycle - Nature Plants This study presents an extensive single-nucleus and spatial transcriptomic atlas of the Arabidopsis life cycle that represents ten distinct developmental time points inclusive of six diverse organs.

From a gene’s single cell expression–through spatial localization–to novel function, and beyond!
Now out @natplants.nature.com
We built a comprehensive spatial-transcriptomic atlas of Arabidopsis, revealing cell-type identities across organs in unprecedented detail

VRN2-PRC2 facilitates light-triggered repression of PIF signaling to coordinate growth in Arabidopsis Osborne et al. show that the angiosperm-specific PRC2 subunit VRN2 is enriched in hypoxic regions of the Arabidopsis shoot, where it is required for stable deposition of H3K27me3 in key PIF4 target ge...

Happy to see our latest paper by @drosborneplantsci.bsky.social et al out today in Developmental Cell @cellpress.bsky.social! We identify a role for VRN2-PRC2 in regulating light-responsive growth in Arabidopsis through the conditional epigenetic repression of PIF signalling. tinyurl.com/swbyff24

Regulatory principles of photoperiod-driven clock function in plants The circadian clock provides a fundamental timing mechanism for plant fitting to seasonal changes in the photoperiod. Although photoperiodic regulatio…

With our new study, we engineered an orthogonal hypoxia-responsive system in plants inspired by mammalian HIF protein degradation. We demonstrated that this system could control protein stability and activity, enabling modulation of Oxygen sensing outputs. Here's how:
