Magnesium is also needed for the activation of glutamine synthase in nitrogen assimilation. In protein biosynthesis, magnesium promotes the binding of ribosome subunits. The lack of magnesium will affect the normal structure of ribosomes and reduce the ability of protein synthesis. Therefore, magnesium is conducive to the synthesis of proteins, and it can also stabilize the ribosomes necessary for the synthesis of protein configurations. Therefore, with the increase of magnesium supply level, the protein content of root and shoot of Oat Seedlings increased. The accumulation of soluble nitrides in plants under magnesium deficiency can easily lead to diseases, such as rice blast and flax leaf spot.
Sulphur is one of the essential nutrients for plants. With the increasing production of crops and feedstuffs, the development of high-concentration fertilizers, the use of clean energy and the successful treatment of atmospheric SO2 pollution, more and more reports about sulfur deficiency have been reported in the world. Among them, Australia, New Zealand and the Americas, Africa, Asia are the majority. According to calculation, China, India and Indonesia account for 80% of the total sulfur demand in Asia.
