Global herbaria are the greatest repositories of information on the plant kingdom. Discoveries of trace element hyperaccumulator plants have historically required time-consuming destructive chemical analysis of fragments from herbarium specimens, which severely constrains the collection of large datasets. Recent advances in handheld X-Ray Fluorescence spectroscopy (XRF) systems have enabled non-destructive analysis of plant samples and here we propose a new method, which we term "Herbarium XRF Ionomics", to extract elemental data from herbarium specimens. We present two case studies from major tropical herbaria where Herbarium XRF Ionomics has led to the discovery of new hyperaccumulator plants and provided valuable insights into phylogenetic patterns of trace element hyperaccumulation. Herbarium XRF Ionomics is a new value proposition for continued funding and retention of herbarium specimens globally.
全球标本馆是植物王国信息的最大宝库。痕量元素超积累植物的发现，历史上需要对标本馆标本的碎片进行耗时的破坏性化学分析，这严重限制了大数据集的收集。最近，手持 X 射线荧光（XRF）光谱仪系统的进步使得对植物样品的无损分析成为可能，在这里，我们提出了一种新的方法，我们称之为“标本馆 XRF 离子组学”，从标本馆标本中提取元素数据。我们提出了两个来自主要热带标本馆的案例研究，其中标本馆 XRF 离子组学导致了新的超积累植物的发现，并为痕量元素超积累的系统发育模式提供了有价值的见解。标本馆 XRF 离子组学是为了继续为全球标本馆提供资金和保留标本而提出的新的价值主张。
