AbstractWe studied molecular order in native plant plasma membranes in the presence of static magnetic fields. Plasma membranes of seeds of the tomato plant were purified, extracted, and applied to a silicon substrate in a buffer suspension and their molecular structure was studied using X-ray diffraction. We observed correlation peaks that we assigned to the lipid and protein components of the plasma membrane. Two field strengths were available: B = 0.126 T and B = 0.208 T. While magnetic fields had no observable effect on protein structure, enhanced lipid order was observed, leading to an increase in the gel components and a decrease in the fluid component of the lipids. © 2013 The Royal Society of Chemistry.
