I study the mycorrhizal ecology of forests. Less hype, more hyphae.

These are all lab studies. I'm not clear how they demonstrate 'fungi transport water from deep in the soil to plant roots'? I agree that they show that water flows through mycorrhizal fungi to roots.

Can you please share the studies that support this post? Thanks

This study doesn't seem to strengthen the hypothesis that mycorrhizal fungi helped plants colonize land. There seems to be a lot of uncertainty around this point. However, I'm the first to admit that I'm not trained in these kinds of analyses, so please straighten me out!

I'm puzzled by '1/3'. Assuming myc fungi can't select C from fossil fuels but receive C in proportion to magnitude of sources, wouldn't the value be < 2%? Screenshot of my calculations below. Thanks for helping me sort this out.
