An ionomic approach is conducted for evaluating the silver distribution, in different soybean plant compartments, as well as its influence on the homeostasis of some macro (P and S) and micro (Cu, Fe, Mn and Zn) nutrients. Silver is added to transgenic and non-transgenic soybean plants as nanoparticles or silver nitrate for comparative purposes. The transgenic plants translocate a higher amount of silver (100 and 65% for silver nanoparticles and silver nitrate expositions, respectively) than non-transgenic, and considering the treatments, the cultivation with silver nanoparticles results in a higher translocation rate (100 and 21% for transgenic and non-transgenic plants, respectively). In addition, significant differences are found (p < 0.05) considering those macro and micronutrients in all plant compartments, mainly in the roots of those treated plants, indicating not only that both silver forms evaluated interfere in the plant metabolism, but also their toxicities.
采用离子组学方法评估了不同大豆植株器官中银的分布情况，以及其对一些大量（P 和 S）和微量（Cu、Fe、Mn 和 Zn）营养元素的体内平衡的影响。为了进行比较，将银纳米颗粒或硝酸银添加到转基因和非转基因大豆植株中。与非转基因植株相比，转基因植株转运了更高量的银（分别为银纳米颗粒和硝酸银暴露的 100%和 65%），并且考虑到处理方式，用银纳米颗粒培养会导致更高的转运率（分别为转基因和非转基因植株的 100%和 21%）。此外，在所有植物器官中，特别是在处理过的植物的根部，发现了那些大量和微量元素的显著差异（p<0.05），这不仅表明所评估的两种银形式都干扰了植物的新陈代谢，而且还表明它们具有毒性。
