tissue-architecture
Tissue-architecture describes the spatial organization and arrangement of plant tissues—how different cell types and tissue layers are coordinated and structured within plant organs. Understanding tissue-architecture is fundamental to plant physiology and development, determining how plants grow, transport water and nutrients, maintain mechanical strength, and respond to environmental stresses.

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
