The post-fertilization archegonium gene network of seedless plants contributed to the origin of seeds - Nature Communications

The authors identify conserved gene networks across fern and angiosperm reproductive development, including between the sporophyte ovule and the fern gametophyte egg-chamber. Repurposing of this netwo...

🌱🧬Root surface epidermal cells sense mechanical tension & activate RAB-A5c-driven growth control. Covered cells are shielded by the root cap Plants use positional cues to link biomechanics with gene expression for directional growth. #plantscience @zoenv.bsky.social www.cell.com/current-biol...

Plant cells at the organ surface use mechanical cues to activate a specific growth-control program

Nemec-Venza et al. show how mechanical signals, such as tissue tension, can activate gene expression in epidermal cells at the surface of Arabidopsis roots. The expression of the edge-specific growth ...

Hairy link... Gouran et al. @bradylabs.bsky.social @plantdevo.bsky.social provide an integrated experimental framework that enables holistic analysis of broomrape parasitism, which may be applied at scale to accelerate resistance gene discovery in #tomato & other hosts 🔗 doi.org/10.1093/pcp/...

4 images showing cellular resolution assessment of broomrape infection in tomato hairy roots. two top panels (a & b) show confocal microscopy of the tomato–broomrape interface. two bottom panels (c & d) show cleared tomato hairy roots with an attached broomrape seedling.

📢 Two postdoc positions available in @mc-caillaud.bsky.social's group (RDP lab, ENS de Lyon), part of an ERC Consolidator. Project: how plant cells orient their division, combining cell biology, molecular genetics, and mechanical modelling. 📅 Deadline: 1 Oct 26 | Start: Nov 26 onwards Details 🧵👇

Recruitment flyer for two postdoc-funded positions in Marie-Cécile Caillaud's group (RDP laboratory, ENS de Lyon, France). Across the top run six scientific images: a line drawing of an Arabidopsis seedling with roots; a 3D digital reconstruction of a shoot apical meristem with orange and purple sectors marking cell lineages; a confocal microscopy image of plant tissue with green cell outlines and red/orange fluorescent nuclei; two paired 3D cell models in orange/green and yellow/purple showing division plane geometry; and a fluorescence microscopy image of a dividing cell with yellow microtubule-like structures and cyan nuclei on a dark background. Below, the title reads "Two Postdoc-funded positions" with an ERC logo, followed by "Deadline: 1st of Oct 2026" and "Starting date: Nov 2026 and onwards" in a bordered box. The body text is organised into sections: PROJECT (describing research into how plant cells orient their division, combining cell biology, molecular genetics, and multiscale mechanical modelling, with a link to the team website), CANDIDATE (looking for motivated candidates with a strong publication record, prior expertise in plant cell biology or biophysics as a plus, working language English), ENVIRONMENT (describing the ERC Consolidator project, the RDP laboratory hosted at ENS de Lyon, an international and gender-balanced working environment, and the city of Lyon), and RECENT PUBLICATIONS (three pinned references: Goldy et al. 2026 in Science Advances, Gascon et al. 2025 in Current Biology, and Lebecq et al. 2023 in Science Advances). An envelope icon box at the bottom right gives instructions to send a single PDF (cover letter, short summary of previous research, CV with publications, and contact details for two to three referees) to marie-cecile.caillaud@ens-lyon.fr.

Have you ever wondered how the epigenome is modified during the transition from seed to seedling? Here, we show that water uptake by Arabidopsis seeds triggers the eviction of the H2B variant H2B.8, thereby revealing replication-independent chromatin reprogramming. www.nature.com/articles/s41...

Replication-independent eviction of the histone variant H2B.8 reveals chromatin reprogramming during seed imbibition - Nature Communications

The transition from seed to seedling requires chromatin reprogramming. By studying the histone variant H2B.8, the authors show that it organizes silent chromatin in dry seeds and reveal that water upt...
