摘要:

镉在人体长期积累可导致严重疾病。稻米是人体摄入镉的主要来源之一。在镉污染土壤中,培育低镉水稻品种是生产低镉稻米最经济且有效的途径。目前,关于水稻镉积累的基因资源挖掘与功能研究已广泛开展,低镉水稻品种筛选也取得初步进展。本文综述了低镉水稻基因和种质资源挖掘及低镉水稻品种选育等方面的研究进展,并对当前低镉水稻新品种培育面临的问题进行了讨论与展望,旨在为低镉水稻的分子育种和安全生产提供理论参考。

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
