OsMGT1 Confers Resistance to Magnesium Deficiency By Enhancing the Import of Mg in Rice

摘要: Magnesium (Mg) is an essential nutrient element for plant growth and plays important role in numerous physiological biochemical processes. Mg deficiency inhibits has become a growing problem crop productions agriculture. However, the molecular mechanisms resistance to plants were not well understood. In this study, we identified transporter gene OsMGT1 that confers rice (Oryza sativa). The expression of was highly induced by shoots. Investigation tissue patterns revealed mainly expressed phloem region; however, remarkably enhanced its xylem parenchyma mesophyll cells Knockout resulted significant reduction content biomass when grown at Mg-limited conditions. Furthermore, sensitivity low-Mg mutants intensified excessive calcium supply. addition, overexpression increased under conclusion, our results indicate import required deficiency, which can be utilized breeding tolerant plants.
