Promoters: Evolution

Evolutionarily conserved promoter elements may direct similar patterns of gene expression in diverse species. Conversely, one of the most important mechanisms for the shaping of new species and new attributes is the evolution of new patterns of gene expression. Strategies aimed at identifying both conserved and evolving promoter elements will be major targets for future study.
