🧬 How can simple gene circuits create complex cell behaviours? James Locke’s team shows how a common genetic circuit, combining positive & negative feedback loops, can be tuned to produce a wide range of gene-expression patterns 🔗 doi.org/10.1038/s414... 🔗 www.slcu.cam.ac.uk/news/how-sim...

Out today in Nature: sex without crossovers. Rhynchospora tenuis makes pollen, fertilises and sets seed, yet 0 crossovers in 10,997 pollen nuclei. Chromosome drive and ~87% seed abortion rebuild the mother's genotype, so the offspring are clones. doi.org/10.1038/s415...

If you’re struggling to get hold of special eclipse glasses, then you can always look at the shadow it produces through a colander. This worked well for us last time.
Fresh preprint online from our group! We find that stomatal maturation IS possible in the embryo, when they lack ERECTA signaling, but then still, only at the cotyledon tip. A thread. www.biorxiv.org/content/10.6...
ERECTA signaling controls the timing of Arabidopsis Guard Cell maturation at the embryonic leaf tip
While cell identities are established early during embryogenesis, these cells remain immature until germination, and the mechanisms enforcing this developmental pause are poorly understood. Embryonic ...

Happy to share some of the auxin Marchantia research we've been working on for a while with @fromani.bsky.social and @jimhaseloff.bsky.social. We confirm long standing suspicions that stem cells in Marchantia exist in an auxin concentration/signalling minimum, and potentially a cytokinin maximum.
Marchantia stem cell maintenance and re-establishment are controlled by MpPIN1-mediated auxin transport and ARF signalling
Meristem organization in land plants depends on coordinated auxin distribution, transport and response, yet how these processes are integrated during vegetative growth of the gametophyte of non-seed p...

Why paying peer reviewers works, according to a journal’s editor-in-chief
A biology journal that paid peer reviewers found that the approach cut the time to a first editorial decision by 85% and maintained high-quality reviews.

“Mechanistic” must be the most abused word in research. Everyone want “mechanistic insights” but it means very different things for a geneticist vs a structural biologist or cell biologist.
