In exchange for all this subterranean service, a tree provides the mycorrhizal fungi with sugar, created through photosynthesis.

为了换取所有这些地下服务，一棵树为根真提供了通过光合作用产生的糖。

Through mycorrhizal networks, fungi can pass resources and signaling molecules between trees.

通过根网络，真可以在树木之间传递资源和信号子。

This is one of the mysteries of the mycorrhizal networks.

And then what about for ecto?

那谁和外生根真呢？

But these mycorrhizal fungi do more than trade minerals, water and sugar with their host tree.

但是这些根真所做的不仅仅跟它们的宿主交换矿物质、水和糖。

But they also run through the soil and eventually can connect with other trees that forms the mycorrhizal network.

但它们也会在土壤中穿行，最终与其他树木连接，形成根网络。

Trees that associate with arbuscular mycorrhizae tend to have more nitrogen and phosphorus in their leaves.

Ectomycorrhizae and arbuscular mycorrhizae specialize in getting different nutrients, and they trade those nutrients to trees at different price points.

外生根和丛枝根别专门获取不同养，将这些养以不同价位与树木交易。

They're called mycorrhizal fungi and these fungi live in and around the roots of trees and other plants.

它们被称为根真，这些真生活在树木和其他植物的根部及其周围。

In fact, almost all terrestrial plants  have root-infecting mycorrhizal fungi.
