This is one of the mysteries of the mycorrhizal networks.

这是菌根网络的奥秘之一。

What would help would be a map of mycorrhizal fungi worldwide.

有帮助的会是全球菌根真菌的地图。

Roughly 80 percent of all plant species are associated with these mycorrhizal fungi.

大概 80% 的植物品种与这些菌根真菌连接。

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

通过菌根网络，真菌可以在树木之间传递资源和信号分子。

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

但是这些菌根真菌所做的不仅仅跟它们的宿主交换矿物质、水和糖。

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，一棵树为菌根真菌提供了通过光合作用产生的糖分。

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，形成菌根网络。

So the experiment Jenny's working on is about trying to get more mycorrhizal fungi into urban soil.

因此 Jenny 在做的实验室努力让更多根菌进入城市土壤。

Across the globe, there are two main types of these mycorrhizal fungi that make up the wood wide web.

在全世界范围内，构成这种木维网的菌根真菌主要有两种类型。

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

事实上，几乎所有的陆生植物都有根部感染菌根真菌。

If this works, we could suddenly have global mycorrhizal maps with 10,000 times more detail than the maps we have now.

如果成功的话，我们就能立刻拥有比已有地图精细 10000 倍的全球根菌地图。

Those signatures help predict what's going on in the soil, where trees trade with mycorrhizal fungi through their roots.

这些特征有助于预测土壤中发生的情况，树木通过根部与菌根真菌进行交易。

But unlike at Harvard Forest, no one here has mapped the relationship between all the trees and their mycorrhizal fungi.

但与哈佛森林不同的是，这里没有人绘制出所有树木与其菌根真菌之间的关系。

These are mycorrhizal fungi that live  around the bases of trees in the deep, dark woods where ghost plants are found.

这些是菌根真菌，生活在幽暗森林深处的树根周围，在那里发现了幽灵植物。

We know the oldest trees have the largest mycorrhizal networks with the most connections to other trees, but these connections are incredibly complicated to trace.

我们知道最古老的树具有最大的菌根网络，与其他树木的连结最多，但这些连结却很难追踪。

Maybe building out this metaphorical mycorrhizal network of climate hubs will help pressure politicians to limit emissions, thereby fixing the inflation problem in the real-world-plant-fungi economy.

也许建立这个隐喻的气候中心菌根网络将有助于向政客施加压力，限制排放，从而解决现实世界植物真菌经济中的通货膨胀问题。

She imagines these hubs trading information with researchers like mycorrhizal fungi trade with trees: they can use the data from big science to make good decisions while also feeding back insights.

她想象这些中心与研究人员交换信息，就像菌根真菌与树木交换信息一样：它们可以利用大科学的数据做出正确的决策，同时反馈见解。

And we combine them into a very, very large dataset, which allows us to make maps of the world's mycorrhizal fungal network, and to make predictions about what we expect to find.

我们将它们组合成一个非常非常大的数据集，这使我们能够制作世界菌根真菌网络的地图， 并对我们期望找到的东西做出预测。
