Sepal shape variability is robust to cell size heterogeneity in Arabidopsis

The paper quantitatively investigates how cell size variation affects sepal shape robustness in Arabidopsis, finding that cell size heterogeneity is not essential for shape robustness.

A 3-component module maintains sepal flatness in Arabidopsis

The paper identifies a 3-component module involving VIP4, ARF3, and VANGUARD1 that maintains sepal flatness in Arabidopsis by regulating cell wall stiffness and growth balance.

Water fluxes contribute to growth patterning in shoot meristems

The paper maps water fluxes in Arabidopsis shoot meristems and shows they influence growth patterning by creating water deficits at the organ-meristem boundary.

Turning plants from passive to active material: FERONIA and microtubules independently contribute to mechanical feedback

The paper investigates the role of FERONIA and microtubules in plant cell mechanical feedback, showing they function as independent pathways to resist stress.

Organ geometry channels cell fate in the Arabidopsis ovule primordium

The paper investigates how organ geometry influences spore mother cell differentiation in Arabidopsis ovule primordium through 3D imaging and growth models.

iDePP: a genetically encoded system for the inducible depletion of PI(4,5)P2 in Arabidopsis thaliana.

The paper introduces iDePP, a system to inducibly deplete PI(4,5)P2 in Arabidopsis thaliana, revealing its role in cortical microtubule organization.

Timing of organ initiation is crucial for robust organ size

The paper shows that DRMY1 regulates sepal size in Arabidopsis by controlling organ initiation timing and growth.

External mechanical cues reveal core molecular pathway behind tissue bending in plants

The paper shows that external mechanical cues drive hook formation in plant hypocotyls, with non-canonical auxin pathways and cellulose microfibrils playing key roles.

The self-organization of plant microtubules in three dimensions enables stable cortical localization and sensitivity to external cues

The paper shows that plant cortical microtubules self-organize into stable configurations in 3D space, adapting to cell shape and responding to external cues.
