Abstract

Abstract:

Long-term accumulation of cadmium (Cd) in the human body can lead to severe diseases. Rice is one of the primary sources of cadmium intake for human. Breeding of low-cadmium rice cultivars was the most economical and effective strategy for producing rice with low Cd in Cd-contaminated soils. Currently, extensive research has been conducted on the mining and functional characterization of genes related to Cd accumulation in rice, and preliminary progress has been made in screening low-Cd rice cultivars. This review summarizes the advances in the discovery of low-Cd genes and germplasm resources, as well as the breeding of low-Cd rice cultivars. It also discusses and prospects the challenges in breeding new low-Cd rice cultivars, aiming to provide a theoretical reference for molecular breeding and safe production of low-Cd rice.

Key words: cadmium, rice, gene identification, low-Cd rice cultivar
