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.

Growth couples temporal and spatial fluctuations of tissue properties during morphogenesis

The paper investigates spatiotemporal fluctuations in plant tissue growth, showing that growth couples temporal and spatial variations through a mechanism called fluctuation stretching.

Growth history leaves a geometric trace in puzzle cells

The paper shows that puzzle-shaped cells record tissue growth history through geometric changes, validated in maize and Arabidopsis with mechanical simulations and imaging.

The ratio of auxin to cytokinin controls leaf development and meristem initiation in Physcomitrium patens

This study shows that the auxin-to-cytokinin ratio controls leaf development and meristem initiation in moss by manipulating hormone levels and observing developmental outcomes.

An optimized pipeline for live imaging whole Arabidopsis leaves at cellular resolution

The paper presents an optimized pipeline for live imaging Arabidopsis leaves at cellular resolution, enabling robust analysis of growth and differentiation in wild-type and mutant leaves.

Cell growth rates coordinate across the width of the leaf to remain flat

The paper analyzes cell growth dynamics in Arabidopsis leaves to show that coordinated growth across the leaf blade is necessary for maintaining flatness, and that the jaw-D mutant disrupts this coordination.

A giant cell enhancer achieves cell-type specificity through activation via TCP and repression by Dof transcription factors

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.
