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
Our foray into single cell and spatial transcriptomics led by Byron Rusnak in GenomeBiology. We found that DRMY1 is required for proper brassinosteroid-mediated coordination of sepal elongation, ensuring balanced growth between inner and outer sepals. link.springer.com/article/10.1...
Ever stretch a plastic bag until it wrinkled? Keeping a thin sheet flat while it rapidly expands is surprisingly difficult. So how do growing plant leaves remain flat as they rapidly grow? Check out our new @currentbiology.bsky.social review, How to Grow a Flat Leaf www.cell.com/current-biol...

Our new year starts of course with new preprint on brassinosteroid signaling tinyurl.com/nhzcfkxd. We re-analyzed the function of Kelch phosphatases, which were previously characterized as protein tyrosine phosphatases that dephosphorylate the critical pTyr200 in the GSK3 kinase BIN2. (1/6)
Plant Kelch phosphatases are Ser/Thr phosphatases involved in cell cycle regulation
Brassinosteroids (BRs) are plant steroid hormones sensed at the cell surface by the membrane receptor kinase BRI1. Activation of BRI1 leads to the dephosphorylation of BZR1/BES1 transcription factors ...
