I want to know the answer to the following question:
What fungus is known to cause uranium content in its symbiotic plant roots to increase?
All the background I'm provided with is that "Some organisms, such as the lichen Trapelia involuta or microorganisms such as the bacterium Citrobacter, can absorb concentrations of uranium that are up to 300 times the level of their environment.". Is that enough to answer the question?
Answer: no
