Genetic Architecture of Domestication-Related Traits in Maize

Genetic Architecture of Domestication-Related Traits in Maize.

Strong directional selection occurred during the domestication of maize from its wild ancestor teosinte, reducing its genetic diversity, particularly at genes controlling domestication-related traits. Nevertheless, variability for some domestication-related traits is maintained in maize. The genetic basis of this could be sequence variation at the same key genes controlling maize-teosinte diffe...

Complex genetic architecture underlies maize tassel domestication

Maize (Zea mays) tassels underwent profound morphological changes during maize domestication and improvement. Although a number of genes affecting maize inflorescence development have been identified, the genetic basis of the morphological changes in maize tassels since domestication is not well understood. Here, using a large population of 866 maize-teosinte BC2 S3 recombinant inbred lines gen...

The Genetic Architecture of Domestication in Animals

Domestication has been essential to the progress of human civilization, and the process itself has fascinated biologists for hundreds of years. Domestication has led to a series of remarkable changes in a variety of plants and animals, in what is termed the "domestication phenotype." In domesticated animals, this general phenotype typically consists of similar changes in tameness, behavior, siz...

The Complex Inheritance of Maize Domestication Traits and Gene Expression

The genetic basis for morphological change in divergent species is a central question in evolutionary biology. The domestication of maize from its wild progenitor, teosinte, is an excellent system to address this question. We explore the large effect on domestication phenotypes of a poorly understood region of the maize genome using a chromosome five specific mapping population. Unlike other la...
