Selection During Maize Domestication Targeted a Gene Network Controlling Plant and Inflorescence Architecture.

ABSTRACT: Selection during evolution, whether natural or artificial, acts through the phenotype. For multifaceted phenotypes such as plant and inflorescence architecture, the underlying genetic architecture is comprised of a complex network of interacting genes rather than single genes that act independently to determine the trait. As such, selection acts on entire gene networks. Here, we begin to define the genetic regulatory network to which the maize domestication gene, teosinte branched1 (tb1), belongs. Using a combination of molecular methods to uncover either direct or indirect regulatory interactions, we identified a set of genes that lie downstream of tb1 in a gene network regulating both plant and inflorescence architecture. Additional genes, known from the literature,
