    "abstract": "A qualitative model is presented, suggesting gravitational information is\ntransduced into biological systems primarily by its effect on spatially\norganised membrane and cytoplasmic flows. Continuous low affinity interactions\nbetween membrane bound cytoskeletal proteins and phospholipid flows that are\nundergoing forced convective and shear driven flows are shown to convert this\ninformation into spatial protein patterns, and hence cell shape. As applied\nhere to plant cells, the feedback mechanism is shown capable not only of\nestablishing the strict nanometer scale parallelism that exists between\nproteins running on the inside and outside of the cell membrane, but also to\npredict its maintainance and the angle of fibre realignment observed during\ntropic responses.",
