Plant Phylogenomics: Defining Synergies Between Plant Systematics and Genome Biology Leebens-Mack, James H. [1], Shan, Hongyan [2], Zahn, Laura [3], Wall, P. Kerr [4], Duarte, Jill Ricker [4], Ma, Hong [4], dePamphilis, Claude W. [4]. A genome-scale view of the evolutionary diversification of land plant transcription factors. Phylogenomic analyses show that gene birth and death rates have varied among transcription factor gene families throughout the evolutionary history of land plants. Comparisons of diversity within and among plant transcription factor families will be presented within the context of the organismal phylogeny and genome duplication events. This approach reveals both commonalities and differences in the demography of transcription factor families. In addition, molecular evolutionary analyses elucidate shifting patterns of selection within some transcription factor families following genome duplications and some speciation events. Understanding the causes and consequences of these dynamics will require additional, phylogentically well-placed model systems for comparative functional studies.
