Transcriptional dynamics and chromatin accessibility in the regulation of shade-responsive genes in Arabidopsis - Genome Biology Background Open chromatin regions host DNA regulatory motifs that are accessible to transcription factors and the transcriptional machinery. In Arabidopsis, responses to light are heavily regulated at...

Accessible chromatin enables rapid recruitment of PIFs to induce expression of shade-induced genes! doi.org/10.1186/s130.... Particularly proud of the excellent work of Sandi Paulišić and Alessandra Boccaccini. Many thanks to all authors who made it happen. @unil.bsky.social @fbm-unil.bsky.social

GI as a dynamic integrator: Synchronizing photoperiod and temperature signals to control flowering time in Arabidopsis GIGANTEA (GI) integrates photoperiod and temperature signals to regulate flowering. Under high temperatures, suppression of GI liquid–liquid phase separation promotes flowering. This illustrates how ...

GIGANTEA acts as a dynamic #signal integrator, integrating #environmental cues like temperature and photoperiod to regulate circadian control as well as flowering and #stress responses in #Arabidopsis.

‘Killswitch’ protein lets scientists study immobilized cellular droplets Synthetic peptide fixes biomolecular condensates, revealing how these enigmatic cell structures actually work.

Nature reports on how scientists have found a way to jam the inner workings of biomolecular condensates. A synthetic ‘killswitch’ protein gives researchers a previously unattainable handle on difficult-to-study cellular structures. 🧪

The story is finally out! Happy to have contributed to the work.

DELLA family proteins function beyond the GA pathway DELLA degradation is controlled not only by gibberellic acid (GA) but also by various GA/GID1-independent factors such as light, temperature, and shade. New insights on the evolution of DELLA family proteins and the biological role of DELLA-like proteins…

A land plant phylogenetic framework for GLABROUS INFLORESCENCE STEMS (GIS), SUPERMAN, JAGGED and allies plus their TOPLESS co-repressor Members of the plant specific family of C1-1i zincfinger transcriptionfactors (ZF-TFs), such as SUPERMAN, JAGGED, KNUCKLES or GIS,regulatediversedevel…

Our latest paper is finally out, showing that it is (somewhat) possible to derive phylogenies from protein sequences with long stretches of intrinsically disordered regions, like for the exciting C1-1i zinc fingers.
