Abstract

Abstract:

Cadmium (Cd) is one of the toxic pollutants, which can not only influence plant growth and development, but also threat human health by cadmium accumulation in plants through food chain. Mutant is an important resource for crop improvement and functional genomics research. This paper summerized the research work and achievemrnt by using various mutants to the molecular mechanism of plant cadmium resistance and accumulation. Based on these studies, the paper put forward the strategy of carring out research on crop cadmium resistance, low\|accumulation mechanism, and molecular breeding by using mutants, so as to provide theoretical guidance for breeding crop cultivars with high cadmium resistance and low\|accumulation.

Key words: crop, mutant, cadmium, molecular mechanism

摘要：

重金属镉是土壤中毒性最强的污染物之一，不但严重影响植物生长发育，而且通过植物体内积累进入食物链危害人类健康。突变体不但是作物改良的重要资源，也是基因功能研究的基础材料。总结了利用各种突变体对植物镉抗性和积累的分子机理所做的研究和取得的丰硕成果，在此基础上提出了参考模式植物在作物上利用突变体开展作物抗镉、低积累机制及分子育种研究的策略，为作物抗镉和低积累品种的选育提供理论指导。
