Abstract/Contents:"Phylogenetic studies of grasses (Poaceae) are advanced in comparison with most other angiosperm families. However, few studies have attempted to build large phylogenetic trees of the family and use these for evaluating patterns of diversification or other macroevolutionary hypotheses. Two contrasting approaches can be used to generate large trees: supermatrix analyses and supertrees. In this paper, we evaluated the suitability of each of these methods for the study of patterns and processes of evolution in the grasses. We collected data from DDBJ/EMBL/GenBank to determine sequence availability and asked how far we are from a complete generic-level phylogenetic tree of the grasses. We generated almost complete tribal-level supertrees (39 tribes) with over 400 genera using MRP methods, described their major clades, assessed their accuracy, and used them for the study of diversification. We generated a proportional supertree, by modifying the original supertree, to remove sampling bias associated with the original supertree that may affect diversification statistics. We used methods that incorporate information on the topological distribution of taxon diversity from all internal nodes of the phylogenetic tree to show that the grasses have experienced significant variations in diversification rates (M statistic P-values <0.001 for the original tree; <0.002 for the proportional tree) and show where on the trees significant shifts in diversification have occurred (seven shifts for the original tree; four shifts for the proportional tree). Such tests have not previously been attempted for the grasses, and we discuss future research directions in this area."
