As a natural environmental factor in the Earth, variations of magnetic field level causes many biological effects, including germination rate, flowering time, photosynthesis, biomass accumulation, activation of cryptochrome, and shoot growth.
[3] Not until recently, Agliassa conducted a similar experiment continuing Xu et al. ’s discovery found out that Arabidopsis thaliana delay flowering by shortening stem length and reduction of leaf size.
[4] Although preliminary experiments have shown a wide range of effects due to the magnetic field, the mechanism has not yet been elucidated.
[6] Based on a few behavior changes due to variations of the magnetic field, many plant scientists have paid attention to cryptochrome being the candidate for the magneto-sensory receptor.
So far, the interactions between signals and magnetoreceptor molecules have not yet discovered, thus leaving potential space for future research while understanding magnetotropism would be significant for improving life forms and ecology such as agriculture.
