Abstract:

To understand the current status of Cd contamination and regulation in rice, this review comprehensively summarizes the following aspects: the absorption and translocation patterns of Cd in rice, Cd accumulation characteristics in different rice varieties and plant organs, the impacts of Cd on rice yield and quality, the effects on seed germination, as well as the influences on rice growth and physio-biochemical processes. Additionally, mitigation strategies for reducing Cd accumulation are systematically discussed. Based on China's current situation of rice Cd contamination, future research directions are proposed: (1) developing novel in-situ passivation materials, such as nano-adsorbent materials, which should have the characteristics of eco-friendly, cost-effective, high-efficiency, and user-friendly features; (2) creating more scientifically sound soil remediation technologies that can efficiently remove various heavy metals without damaging soil structure and ecological balance; (3) employing novel molecular breeding techniques to cultivate Cd-tolerant and stable ultra-low Cd-accumulating rice varieties, along with developing corresponding cultivation practices. This study aims to provide valuable references for Cd contamination control.
