Abstract:

Zinc (Zn) is an essential micronutrient for animals and plants. Zinc deficiency or excess can seriously affect the growth and development of rice. Maintaining zinc content in rice at a certain level is helpful to improve the yield and quality of rice, increase the zinc content in grain, and solve the current problem of zinc deficiency in human body to a certain extent. Therefore, it is important to understand Zn uptake, transport, distribution, and other molecular mechanisms regulating Zn homeostasis in rice. In this review, we briefly summarized the importance of zinc in plants, especially the ion transporters in rice and the molecular mechanisms. The roles of these ion transporters in the uptake of Zn from soil, the transport from root to shoot, and the distribution of Zn to various parts of rice were summarized. Some molecular mechanisms related to ion transporters were also summarized. This study provides reference for the mining of zinc homeostasis regulatory genes in rice, the study of molecular mechanism, and the creation of high zinc rice germplasm.
