A swainsonine survey of North American Astragalus and Oxytropis taxa implicated as locoweeds

Pathogenesis and preventive treatment for animal disease due to locoweed poisoning.

Locoweeds are perennial herbaceous plants included in Astragalus spp. and Oxytropis spp. that contain the toxic indolizidine alkaloid swainsonine. The livestock that consume locoweed feeding can suffer from a type of toxicity called "locoism." There are aliphatic nitro compounds, selenium, selenium compounds and alkaloids in locoweed. The toxic component in locoweeds has been identified as swai...

The Genome of Undifilum oxytropis Provides Insights into Swainsonine Biosynthesis and Locoism

Undifilum oxytropis is a fungal endophyte of locoweeds. It produces swainsonine, which is the principal toxic ingredient of locoweeds. However, the genes, pathways and mechanisms of swainsonine biosynthesis are not known. In this study, the genome of U. oxytropis was firstly sequenced and assembled into a 70.05 megabases (Mb) draft genome, which encoded 11,057 protein-coding genes, and 54% of t...

Astragalus and Oxytropis Poison Livestock with Different Toxins

Fetotoxicity of Astragalus lentiginosus (Locoweed) in Spanish Goats

Locoweed species—Astragalus and Oxytropis spp. that contain the indolizidine alkaloid swainsonine— are widely distributed on rangelands in North and South America, Mexico, China, and other rangelands throughout the world. Other range plant species including Sida spp. (Seitz et al. 2005), Ipomoea spp. (Damir et al. 1987), and Swainsona spp. (Laws and Anson 1968) from Brazil, Africa, and Australi...
