    For those with the stomach for a little more detail: this entire process is called phytomining, or extracting minerals using plants in an environmentally sound manner. That wheat is a hyper-accumulator means it can naturally take up gold and not be harmed – and it happens to do so in amounts larger than any other plant. Those handy little root enzymes make the gold soluble, which means it can be stored in the stems and branches, and later – when those stems and branches are incinerated – the gold can be extracted from the ash.

    The research represents a win on multiple levels. First, there are the obvious potential socio-economic benefits: food production, job creation, and phytomining itself is more economical than other contemporary mining methods. ........
