MU Graduate Student Wins First Place Award at ASA-CSSA-SSSA Conference

Columbia, Mo -- Julian Lenis, Graduate Student in Dr. Kristin Bilyeu's laboratory, received first place in the Crop Breeding & Genetics Division's Graduate Student Poster competition entitled "Soybean Seed Lipoxygenase Genes: Molecular Characterization and Development of Molecular Marker Assays".

Lipoxygenases are enzymes that play a role in the development of unpleasant flavors in foods containing soybean. Even though non-functional variants for the three seed lipoxygenases had been previously identified in separate soybean lines, the cause of the mutations at the DNA level for two of the lipoxygenaseswas not known.

The poster described the genetic basis of the mutations at two of the seed lipoxygenase genes and the development of molecular markers which allow the identification of soybean plants carrying those mutant genes.

The molecular marker assays reported, represent a rapid, simple, and accurate alternative to evaluate the genetic make-up of individuals, allowing for a very efficient development of lipoxygenase-free soybean varieties.

The American Society of Agronomy (ASA)-Crop Science Society of America (CSSA)-Soil Science Society of America (SSSA) held their 2010 International Annual Meeting on October 31 – November 4, 2010 at Long Beach, California. The Society hosted approximately 3,000 scientists, professionals, educators, and students.

The next ASA, CSSA, and SSSA Annual meeting will be held on October 16-19, 2011 in San Antonio, Texas.
