thumb|A tree that has grown sideways due to the wind Thigmomorphogenesis involves plants altering their growth and development in response to mechanical stimuli, such as touch, wind, or rain. This process begins with the perception of mechanical forces by cellular mechanosensors, followed by their transduction into signal transduction pathways cascades, and culminating in changes in gene expression and hormone activity. The response integrates diverse molecular components, including mechanosensitive ion channels, receptor-like kinases, the cytoskeletal elements, phytohormones, and transcriptio

This process begins with the perception of mechanical forces by cellular mechanosensors, followed by their transduction into signal transduction pathways cascades, and culminating in changes in gene expression and hormone activity. The response integrates diverse molecular components, including mechanosensitive ion channels, receptor-like kinases, the cytoskeletal elements, phytohormones, and transcription factors, which collectively drive both immediate physiological and long-term morphological adaptations.
Early observations noted that greenhouse-grown plants were often taller and more slender than stockier plants grown outdoors, where they were exposed to natural mechanical stresses. The term "thigmomorphogenesis" is derived from Ancient Greek θιγγάνω (thingánō, "to touch"), μορφή (morphê, "shape"), and γένεσις (génesis, "creation").
