Summary

DeepGenes incorporates genes and traits related to root architecture, anatomy, and deep rooting discovered through phenotyping and LEADER into genomic selection models. Initial gene discovery was completed through GWAS of the Wisconsin Diversity panel of inbreds. Multiple genes are in various stages of validation through mutant and transgenic studies. A genomic selection model is being developed through phenotyping two panels of hybrids grown under nitrogen and water stress conditions. This model will select for the genetic structure underlying a suite of traits that we identify as being "carbon optimized."
