Abstract

We present here the concept of "in-plant" NMR and show that high-resolution NMR spectroscopy is suitable for the analysis of intact plants and can be used to follow the changes in the intraorganismal molecular composition over long time periods. The NMR-based analysis of the effect of different concentrations of heavy water on the aquatic plant Vesicularia dubyana revealed that due to the presence of specific adaptive mechanisms this plant can sustain the presence of up to 85% of D2O. However, it dies in 100% heavy water.

摘要

我们在此提出“植物体内”核磁共振（NMR）的概念，并表明高分辨率核磁共振光谱适用于完整植物的分析，可用于长期跟踪生物体内分子组成的变化。基于核磁共振对不同浓度重水对水生植物细叶铁皇冠影响的分析表明，由于存在特定的适应机制，这种植物能够在高达85%的重水存在下存活。然而，它在100%重水中会死亡。
