What traits can be improved in corn with the ufo1 gene’s help?
“Certainly, stress tolerance, but also likely seed development, which has implications in seed yield as well as improved biomass,” Chopra said. “And we would like to develop a better plant type that could grow in more dense culture, yet still be more productive. And finally, we need to look at resiliency and sustainability. Can we breed corn lines that get the same amount of yield with lower fertilizer inputs and need less water?”
Chopra started research on the Maize ufo1 gene because of its association with an orange/red pigmentation in the mutant corn line. Celebrated maize geneticist Charles Burnham, at the University of Minnesota, identified this conspicuous ufo1 mutant circa 1960. Another well-known maize geneticist, Derek Styles, with the University of Victoria, Canada, a student of Burnham’s, then chose the name, which stands for “unstable factor for orange.�
