Protein derived from cottonseed for human nutrition is one step closer to reality

By: Kay Ledbetter Contact: Dr. Keerti Rathore – rathore@tamu.edu Cottonseed ground into flour to deliver protein to millions of people, a project to which Dr. Keerti Rathore has devoted more than half his professional career, is one step closer to reality. Rathore, a Texas A&M AgriLife Research plant biotechnologist in College Station, received word that Texas A&M’s “Petition for Determination of Non-regulated Status for Ultra-Low Gossypol Cottonseed (ULGCS) TAM66274” has been approved by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service, or APHIS.

Engineered cotton uses weed-suppression chemical as nutrient

Writer: Kay Ledbetter, 806-677- 5608, skledbetter@ag.tamu.edu Dr. Keerti Rathore, 979-862-4795, rathore@tamu.edu   COLLEGE STATION – A newly developed fertilizer system will provide nutrition to engineered cotton crops worldwide and a deadly dose to weeds that are increasingly herbicide resistant, according to a Texas A&M AgriLife Research study. The new system applies phosphite to cotton crops engineered to express a certain gene — a gene that makes cotton able to process the phosphite into nutrition while the same compound suppresses weeds that are unable to use it, researchers said….

Genetic discovery another tool in battle against wheat pests

Writer: Kay Ledbetter, 806-677-5608, skledbetter@ag.tamu.edu Contact: Dr. Shuyu Liu, 806-677-5600, SLiu@ag.tamu.edu AMARILLO – Greenbug and Hessian fly infestations can significantly reduce wheat yield and quality in Texas and worldwide. Breeding for resistance to these two pests using marker-assisted selection just got a new tool from a Texas A&M AgriLife Research study. Because genetics is the most economical strategy to minimize losses, AgriLife Research wheat geneticist Dr. Shuyu Liu began two years ago searching for breeder-friendly markers for those two insects. This step is a continuation of ongoing genetic… Read More →

New wheat streak mosaic virus resistance genetic markers developed

Advancement made in battle of major disease in the Great Plains Writer: Kay Ledbetter, 806-677-5608, skledbetter@ag.tamu.edu Contact: Dr. Shuyu Liu, 806-677-5600, SLiu@ag.tamu.edu Dr. Chor Tee Tan, 806-677-5600, chor_tee.tan@ag.tamu.edu AMARILLO – The Wsm2 gene is located on chromosome 3BS in wheat and most recently eight tightly linked flanking markers have been identified and mapped. To most, that means very little. To Texas A&M AgriLife Research geneticists and breeders, it’s the key to battling one of the most important biotic stresses affecting wheat.
