LUBBOCK, Texas (RFD-TV) — A new multi-institutional effort led by the Donald Danforth Plant Science Center aims to identify the genetic traits that make sorghum one of the most stress-tolerant bioenergy crops in U.S. agriculture.

Backed by a $2.5 million DOE grant, the three-year project focuses on how sorghum responds to drought, heat, and other environmental pressures — knowledge that could expand production into resource-limited regions without competing with food crops.
Researchers will analyze natural genetic variation, gene networks, and molecular responses across diverse sorghum lines grown in sharply contrasting field environments in Missouri and Arizona. High-resolution, sensor-based phenotyping, remote sensing, GeoAI tools, and gene-editing methods will be used to link plant genetics to field performance, including oxidative stress biomarkers and morphological changes.
The project unites teams from the Danforth Center, the University of Arizona, and Saint Louis University, pairing plant genetics with advanced sensing systems that capture how sorghum responds across entire growing seasons.
Farm-Level Takeaway: Stronger sorghum genetics could enhance the resilience of bioenergy crops and broaden production options for growers in harsher climates.
The closure of Lubbock Feeders highlights mounting pressure on the U.S. cattle supply, according to the Texas Cattle Feeders Association, as border restrictions and costs strain feedyards.

From soil to harvest. Top Crop is an all-new series about four of the best farmers in the world—Dan Luepkes, of Oregan, Illinois; Cory Atley, of Cedarville, Ohio; Shelby Fite, of Jackson Center, Ohio; Russell Hedrick, of Hickory, North Carolina—reveals what it takes for them to make a profitable crop. It all starts with good soil, patience, and a strong planter setup.
