Mediators of Arabidopsis root skewing and phototropism in microgravity

This reasoning chain connects the actin cytoskeleton’s suppressive effect on root skewing in microgravity, the disruption of gravity-sensing auxin gradients, and the integration of multiple environmental signaling pathways in Arabidopsis. It synthesizes data from molecular, cellular, and physiological perspectives to explain observed root growth patterns and their modulation by microgravity.

Evidence

“Merkys and Darginaviciene (1997) describe experimental evidence concerning plant responses to gravity stimuli (gravitropism).”
