简介：
Overview
This protocol describes a method to test the hypothesis that the reversal of the effective geomagnetic field (GMF) induces differential gene expression and alters the morphology of Arabidopsis thaliana. A triaxial octagonal system of Helmholtz coil-pairs was used to artificially generate reversed GMF conditions in the plant growth chamber.
