摘要

Magnesium (Mg2⁺) is an essential macronutrient for plants, playing a critical role in various physiological and biochemical processes. It serves as a cofactor for numerous enzymes, stabilizes ribosomes, and serves as the central component of chlorophyll, making it indispensable for photosynthesis. The regulation of magnesium homeostasis in plants is mediated by a complex network of transport systems that facilitate the uptake, distribution, and storage of Mg2⁺ within the plant. This review aims to provide a comprehensive overview of magnesium regulatory mechanisms in plants, focusing on molecular function, interactions with other transport mechanisms, hormonal regulation, and signaling pathways.
