The distribution of Mo was significantly different to those of other elements, such as K, P, and Mg. It was also confirmed that this typical enrichment of Mo was not dependent on the region where the peanut seed was planted. The enrichment of Mo was observed in the radicle of peanut seed, and was further confirmed by the isotopic ratio of Mo.
