plant-cytoskeleton
The plant cytoskeleton is a dynamic network of protein filaments that maintains cell structure and coordinates intracellular activities, including the unique process of cell plate formation during cell division. In plants, the cytoskeleton is essential for cell expansion, organelle trafficking, and the organization of growth patterns, making it fundamental to plant development and how cells respond to environmental signals.

Plant cells use their internal actin skeleton to maintain proper division orientation, even when cell shape and mechanical stress in tissues suggest otherwise. This research clarifies how plants coordinate structural forces to ensure tissue development follows the right pattern.
Actin cytoskeleton is essential for maintaining cell division plane orientation independent of cellular geometry
Cell divisions typically follow the shortest volume-enclosing path but can deviate perpendicular to growth axis in response to mechanical cues
Tissue-scale mechanical stress guides division orientation, but integration mechanisms require further investigation
