Abstract

Cadmium (Cd) contamination in farmland soil has become a global environmental concern, resulting in Cd pollution in crops. It is urgent to address this issue, and recent research has suggested that exogenous application of nutrient elements, including boron (B), is an effective strategy to decrease Cd accumulation in crops. Boron, an essential micronutrient for plants, plays a key role in maintaining cell integrity, promoting nitrogen metabolism, and enhancing nutrient absorption. Boron enhances Cd tolerance and reduces Cd accumulation in crops by regulating ROS homeostasis, heavy metal transport proteins, and promoting Cd chelation onto cell walls. However, the precise mechanism by which B regulates Cd accumulation remains unclear. This paper summarizes the physiological, biochemical, and molecular mechanisms by which B regulates Cd accumulation in crops. We believe that the rational application of B in light to moderate Cd-contaminated areas could effectively reduce Cd accumulation in crops, ensuring the safety of agricultural products in these regions.

硼在降低作物镉积累中的作用和机制

农田土壤镉（Cd）污染已成为一个全球性的环境问题，导致作物镉污染。近年来的研究表明，外源施用包括硼在内的营养元素是降低作物镉积累的有效策略。硼是植物必需的微量元素，在维持细胞完整性、促进氮代谢、增强养分吸收等方面起着关键作用。硼通过调节活性氧稳态、重金属转运蛋白和促进Cd在细胞壁上的螯合作用，增强作物对Cd的耐受性，减少Cd的积累。然而，B调控Cd积累的确切机制尚不清楚。本文综述了B调控作物Cd积累的生理、生化和分子机制。我们认为，在轻、中度Cd污染地区合理施用B能有效降低Cd在作物中的积累，保证这些地区农产品的安全。
