Growth directions and stiffness across cell layers determine whether tissues stay smooth or buckle

The paper shows that growth direction and stiffness differences between epidermal layers cause buckling in Arabidopsis sepals, and that restoring growth alignment and stiffness can prevent buckling.

Plant cells at the organ surface use mechanical cues to activate a specific growth control programme

The paper shows that surface epidermal cells in plant roots use mechanical cues to activate a growth control program involving RAB-A5c, enabling directional growth.

A mechanohydraulic model supports a role for plasmodesmata in cotton fiber elongation

The paper develops a mechanohydraulic model to study how plasmodesmal permeability affects turgor pressure and cotton fiber elongation, finding it critical for growth.

Gradient in cytoplasmic pressure in the germline cells controls overlying epithelial cell morphogenesis

The paper shows that a gradient of cytoplasmic pressure in nurse cells controls epithelial cell flattening via TGFβ signaling in Drosophila ovaries.
