How are #plant #leaf epidermal cells patterned? @roederlab.bsky.social &co show that the pathway controlling #GiantCell formation in #sepals also controls cell size in #Arabidopsis leaves, via cell-autonomous & stochastic specification @plosbiology.org 🧪 plos.io/491F1qQ
Excited to announce our paper is out! Congrats to @pauformosa.bsky.social, @gweissbart.bsky.social, Frances Clark, and Xihang Wang on this fun and beautiful story. We answered a question about the randomness of giant cell spacing that I have had for at least 15 years.

We found that cytokinin-induced LBDs drive radial (secondary) growth in Arabidopsis root by reshaping primary cell wall pectin, in part through four pectate-lyase-like genes. Huge congrats to the fantastic postdocs who led this work: Lingling Ye and Xin Wang. 1/x www.nature.com/articles/s41...
Cambium LBDs promote radial growth by regulating PLL-mediated pectin metabolism - Nature Plants
This study reveals that LBD transcription factors in the cambium drive radial plant growth by regulating PECTATE LYASE-LIKE (PLL) enzymes that remodel cell wall pectin, promoting cell expansion.

Why are leaf cells of so many different sizes?
Our paper explores how giant cells form!
We also provide automatic cell-type classification and perform statistical quantification of cell spatial organization.
If interested, check it out in @plosbiology.org. Thanks Pau and @roederlab.bsky.social
