植物基因工程技术的应用已使改变植物内污染离子浓度的设想成为可能。然而,对于植物根系吸收污染离子的生理和生物化学特性,植物如何将污染离子从根系运输到茎、籽粒、果实、茎秆,如何积累污染离子的机理目前尚未弄清。由于缺乏植物体内离子吸收和运转机理的支持,难以实现利用 The application of plant genetic engineering techniques has made possible the idea of ​​changing the concentration of contaminated ions in plants. However, the mechanism of how plants transfer contaminated ions from roots to stems, grains, fruits, and stalks and how they accumulate contaminant ions has not yet been clarified for the physiological and biochemical characteristics of plant roots absorbing contaminated ions. Due to the lack of plant ion absorption and transport mechanism support, difficult to use
