The role of geometry in morphogenesis Read this Review from our special issue #DevSIextracellular by Ryan Harrison, Olivier Hamant and @timesaunders.bsky.social. journals.biologists.com/dev/article/...

Role of geometry in shaping tissues. Multiple factors, including cell shape (top left), boundary constraints (top right), topological inputs (bottom left) including from different cell alignment defects (±1/2) and biophysical factors (bottom right) impact how the final tissue form emerges (centre). Centre shows images of a 48 h neuruloid (left; magenta, DAPI; green, actin) and a young Arabidopsis flower (right) treated with oryzalin (depolymerised microtubules) thus showing isotropic growth, but no defect in patterning (organs are still initiated in the right position).

Why do primary plant tissues hold their shape? We are told it's because of turgor pressure—but how does that work mechanically? We investigated how pressurized cylindrical structures support themselves. Read here: doi.org/10.1039/d6sm... Funded by @hfspo.bsky.social www.plantbiomechanics.net

Inflorescence meristem cell identities: (A) Force-directed graph layout of clusters associated with inner cell layers such as early primordia (EP), undifferentiated cells, procambium, xylem parenchyma and cortex. Clusters are represented by different colours. (B) Schematic illustration of selected cell identities in the primary stem and inflorescence meristem. Procambial strands arise in developing primordia and give rise to vascular bundles, which subsequently differentiate into phloem, cambium and xylem within the primary stem. The exact locations of cell identities in the primary stem are schematically represented rather than accurately portrayed. Illustration by first author first author Dr Sebastián Moreno-Ramírez.

Does hidden protein biology live in the suboptimal alignment space? When we align two divergent proteins, we usually trust a single optimal alignment. 🧬 But what if the real structural signal lies in the space of near-optimal solutions? With EMERALD-UI you can unfold this perspective.
