New preprint!
SOSEKI polarity proteins are mechanoresponsive integrators linking growth and tissue mechanics during lateral root formation. Their polarity marks growth boundaries and reorganises in response to mechanical alterations —reshaping how we think about axis formation.

Role of cAMP in TIR1/AFB auxin signaling: open issues
The canonical mechanism by which the phytohormone auxin regulates transcription has been one of the cornerstones of plant signaling. The recent unexpected discovery of cyclic AMP (cAMP) as a second messenger in this pathway has revised its foundations while leaving many open questions and gaps in our understanding; these will be discussed in this forum article.

It is with great sadness that we heard of John Gurdon’s passing this week. Not just one of our 100 extraordinary biologists, but truly one of a kind, he was a pioneer, whose vision and personality inspired biologists worldwide.

ABP1/ABL3-TMK1 cell-surface auxin signaling targets PIN2-mediated auxin fluxes for root gravitropism
In gravistimulated roots, gravity perception in the columella redirects the flow of
the plant hormone auxin toward the lower root side, where it inhibits cell elongation
for downward root bending. Thi...

These historical threads by @somssich.bsky.social about various fundamental aspects of plant biology, and the long process of discovery, linking papers from a century ago to very recent publications, are such a joy to read, every single time.
#PlantScienceClassics #19: Root gravitropism: 120 years ago the starch-statolith theory was described, ~100 years ago the Cholodny-Went theory proposed, and 25 years ago the directional auxin flow was mapped as reverse fountain in the root tip. #Phytohormones #Gravitropism #Auxin #PlantScience
