This is a coordinated research approach between the USDA-ARS-Poisonous Plant Research Lab, Logan, UT and the Rangeland Research Group and College of Agriculture and Home Economics at New Mexico State University in Las Cruces, NM. The proposed joint research will include methods to: 1) better understand the ecology of locoweeds in this region which includes the Southern High Plains and Canadian Pecos Valleys of West Texas and eastern New Mexico; 2) understand more fully the biological characteristics of the locoweeds which includes the role of a newly discovered endophyte (Undifilum) in toxin (swainsonine) production within the plant and plant hardiness; 3) develop sound methods to understand the biology of the endophyte and employ molecular tools to determine if it can be supressed; 4) reduce the toxic effects in cattle and improve rangeland utilization through grazing strategies; 5) better evaluate locoweed's effects on early reproduction in cow calf operations; 6) identify biomarkers for improved diagnostics and prognosis of locoweed poisoning; and 7) develop a holistic management program to reduce livestock losses and improve the economic stability in this region.
