Spiral phyllotaxis in the moss Physcomitrium patens emerges from simple division rules of the apical cell Cammarata et al. explore how cell division orientation generates phyllotaxis in moss with a unicellular meristem. They show that successive rotational divisions in the apical cell are precisely placed...

How moss makes a spiral of leaves through a rotating asymmetric division of the apical cell meristem--our paper is out @currentbiology.bsky.social today! @soestrauss.bsky.social Richard Smith, Joe Cammarata

Quantification of cell‐type‐specific plasmodesmata distribution in Arabidopsis roots reveals spatial and patterning dynamics Plasmodesmata are cytoplasmic channels essential for intercellular communication in plants; yet their organ-scale distribution and regulation remain poorly understood. Here, we establish a quantitati...

How are plasmodesmata distributed across tissues? 🌱

Davis et al. developed a 3D quantitative imaging pipeline to map pit fields at cell-type resolution in Arabidopsis roots.
They’re developmentally reallocated and spatially patterned by BR signaling.

A common pathway controls cell size in the sepal and leaf epidermis leading to a nonrandom pattern of giant cells Arabidopsis leaf epidermal cells have a wide range of sizes and ploidies, but the mechanisms patterning their size and spatial distribution remain unclear. This study shows that the pathway controllin...

Check out our story in @plosbiology.org about how a nonrandom, clustered giant cell pattern forms in the sepal and leaf epidermis! It has been a great journey with @gweissbart.bsky.social, Frances Clark, Xihang Wang, @roederlab.bsky.social and co-authors.
