| Abstract: | Zinc(Zn)is one of the essential micro-elements for human health. Rice is the main staple food crop in the world, however,the Zn content in rice, especially in milled rice, is very low, thus improving Zn content in rice could effectively alleviate human dietary Zn deficiency. The paper reviewed the progresses on the genetic variability of Zn content in rice, the distribution patterns of Zn in the different parts of rice, the patterns of inheritance pattern, QTL mapping, gene cloning and its genetic breeding, which would provide important references for molecular breeding of Zn-enriched rice. |
