ABSTRACT

The Earth?s magnetic field (Geomagnetic field) is an inescapable environmental factor, experienced by all living organisms including plants. Despite the progresses made in the field of plant senses the impact of Geomagnetic field (GMF) on plant growth and development is not fully explored. Variation of exposure intensity may influence a plethora of events at cellular, biochemical or molecular level asserting it as a positive or stressful factor depending on the plant species. In these context experiments elucidating the bio stimulation effect can address issues like „zero hunger challenge? and the global growing problem of malnutrition. Study of the correlation of GMF reversal with plant evolution and mass extinction and the plausible role of magnetoreception can open new horizons to understand the very existence of life from simple magneto tactic bacteria to human beings to the whole biosphere. Further the impact of GMF effects can pave the way for designing sustenance system in future space expedition.
