Relationship Between the Endophyte Embellisia spp. and the Toxic Alkaloid Swainsonine in Major Locoweed Species (Astragalus and Oxytropis)
A survey of the major locoweeds from areas where locoweed poisoning has occurred and found species found to contain the fungal endophyte and produce substantial amounts of swainsonine were A. mollissimus, A. cibarius, and O. sericea.
