From Acorus to Zingiber – assembling the phylogeny of the monocotyledons.

Monocots comprise more than 65,000 species of flowering plants, occur in most habitats and dominate several, and provide the basis for the great majority of the human diet. They also account for much of the commerce in bulbs and cut flowers. With support from the NSF Assembling the Tree of Life (AToL) Program, we – and more than 30 collaborators worldwide – plan to use a revolutionary approach to develop a definitive family tree for the monocots over the next five years, and then use that tree to infer relationships among different groups and their evolutionary history across the globe. To do this, we will sequence the entire plastid genome and all mitochondrial genes for some 600 species representing every monocot family and subfamily. We will also sequence several single-copy nuclear genes for a nested subset of 150 species, and 50-100 transcriptomes. The transcriptomes alone will provide information on thousands of nuclear genes. The resulting avalanche of genetic information from all three plant genomes should provide the basis for the most powerful analysis of evolutionary relationships among any group of organisms studied to date. We will also score 600 extant monocots and 75 fossils for 200 morphological characters, enabling us to determine which traits characterize different groups, and how they have evolved over time. The resulting insights into monocot phylogeny should provide the foundation for many new studies in physiology, ecology, biogeography, and genomics. Studying transcriptomes may identify many new genes associated with traits absent from model plants. Comparisons of nuclear, mitochondrial and plastid genes from diverse monocots should greatly enhance our understanding of gene and genome evolution in angiosperms. Web access to the data, family trees, and conclusions from the study will be provided to researchers, students, and teachers around the world.
