Reshaping of the maize transcriptome by domestication
Through domestication, humans have substantially altered the morphology of Zea mays ssp parviglumis (teosinte) into the cur-rently recognizable maize This system serves as a model for study-ing adaptation, genome evolution, and the genetics and evolution of complex traits To examine how domestication has reshaped
Reshaping of the maize transcriptome by domestication
The system domestication for investigating of maize domestication, from its wild genome progenitor evolution, is a model and system for investigating domestication, genome evolution, and response to selection (1-4) Cytogenetic and molecular analyses of maize domestication have identified Zea mays ssp parviglumis

five genes that have taken place during the domestication of maize (reviewed by White and Doebley 1998) Two of the trait differences between maize and teosinte have each been found to be caused in large part by alleles at single major loci, teosinte branched 1 (Doebley et al 1995) and teosinte glume architecture 1 (Dorweiler et al 1993)
grassy tillers1 promotes apical dominance in maize and
domestication Human selection has generated maize plants that produce very few basal lateral branches, known as tillers Although tiller buds are initiated, the nascent branches ultimately arrest and fail to grow out, which results in the plant’s familiar dominant central stalk (Fig P1A) The maize gt1 mutant, in which the

Domestication of Maize1 by John Smalley and Michael Blake Elaborating on the recent suggestion by Hugh H Iltis that the di-rect ancestor of maize was initially domesticated not for its grain but for its sugary pith or other edible parts, this article proposes that during the initial period of maize domestication the stalk
