Data for Native mycorrhizal fungi improve milkweed growth, latex, and establishment while some commercial fungi may inhibit them

Arbuscular mycorrhizal (AM) fungi are root symbionts that can facilitate plant growth and influence plant communities by altering plant interactions with herbivores. Therefore, AM fungi could be critical for the conservation of certain rare plants and herbivores. For example, North American milkweed species are crucial hosts for monarch butterflies (Danaus plexippus). Understanding how mycorrhizal composition affects milkweeds will have direct impacts on the conservation and restoration of both increasingly threatened guilds.

We present data from three studies on the effect of AM fungal composition on milkweed growth, latex production and establishment. First, we grew 7 milkweed species with and without a mixture of native mycorrhizal fungi. We assessed how important fungal composition is to milkweed growth and latex production by growing 4 milkweed species with 7 fungal compositions, as single species inoculations with 4 native fungi, a mixture of native fungi, a single commercial f...

丛枝菌根（Arbuscular mycorrhizal, AM）真菌是一类根系共生微生物，可通过调控植物与植食性动物的种间互作促进植物生长，并进而影响植物群落组成。因此，AM真菌对于部分珍稀植物及植食性动物的保护工作至关重要。例如，北美马利筋属植物是黑脉金斑蝶（Danaus plexippus）的关键寄主。明晰菌根真菌群落组成对马利筋的影响机制，将对这两类日益受到威胁的类群的保护与修复工作产生直接的积极作用。
本数据集涵盖三项关于AM真菌群落组成对马利筋生长、乳汁产生及定植过程影响的研究数据。其一，我们对7个马利筋物种分别施加本地菌根真菌混合物与无接种对照处理，以评估真菌组成对马利筋生长与乳汁产生的重要性；其二，我们选取4个马利筋物种，设置7种真菌接种处理组合，包括4种本地真菌的单菌种接种、本地真菌混合接种以及单一商业……
