'Orphan Gene' to Boost Protein Content of Staple Crops

A new study conducted by scientists from Iowa State University (ISU) shows that a gene found only in Arabidopsis can increase the protein content of staple crops. The gene regulates the protein content in Arabidopsis seeds and leaves, and the research team calls it an 'orphan gene' because it is not present in the genome of any other organism.

The researchers showed that the orphan gene works in rice, corn, and soybeans. Ling Li, ISU adjunct assistant professor of genetics, development and cell biology said, "Most of the world relies on plants as a major protein resource. And protein that comes from animal sources requires more water, energy and resources to produce, so a diet that relies more on protein-heavy plants is more sustainable."
