description | Nutrient antagonism typically refers to the fact that too high a concentration of one nutrient inhibits the absorption of another nutrient. In plants, Ca2+ (Calcium) and Mg2+ (Magnesium) are the two most abundant divalent cations, which are known to have antagonistic interactions. Hence, maintaining their homeostasis is crucial for plant growth and development. In this study, we showed that MTP10 (Metal Tolerance Protein 10) is an important regulator for maintaining homeostasis of Mg and Ca in Arabidopsis. The mtp10 mutant displayed severe growth retardation in the presence of excess Mg2+, to which the addition of Ca2+ was able to rescue the phenotype of mtp10 mutant. Additionally, the deficiency of Ca2+ in the culture medium accelerated the high-Mg sensitivity of the mtp10 mutant. The yeast complementation assay suggested that AtMTP10 had no Ca2+ transport activity. And the ICP-MS data further confirmed the antagonistic relationship between Ca2+ and Mg2+, with the addition of Ca2+ reducing the excessive accumulation of Mg2+ and high-Mg inhibiting the uptake of Ca2+. We conclude that the Arabidopsis MTP10 is essential for the regulation of Mg and Ca homeostasis. |
