    Scope & contentSometime between five million and 13 million years ago, both maize and soybeans underwent genome duplications, but Purdue University scientists believe that they happened in very different manners.

    Damon Lisch, associate professor in the Department of Botany and Plant Pathology, and Jianxin Ma, professor in the Department of Agronomy, studied the evolution of these major crop plants’ genomes. They wanted to understand the ways in which genomes duplicate – creating multiple copies of genes – and how those genomes change over time.

    In maize, Lisch and Ma believe the duplication happened when two species of grass with similar genomes crossed, like distant cousins…Read more.
