Abstract
DNA sequencing studies of the granule-bound starch synthase gene (GBSSI) indicate the presence of two loci in Viburnum. Gene trees from separate and combined phylogenetic analysis of these loci are generally congruent with each other and with trees from previous analyses, especially those of Donoghue et al. (2004) based on nuclear ribosomal ITS and chloroplast trnK intron DNA sequences. Specifically, our GBSSI trees confirm (i) the monophyly of some and non-monophyly of other traditionally recognized taxonomic sections, (ii) the presence of three major supra-sectional lineages within Viburnum, and (iii) the resolution of many species relationships within the section-level clades. Basal relationships within Viburnum remain uncertain; in particular, the position of the root, relationships among the supra-sectional clades, and the exact placement of several smaller groups (e.g. V. clemensiae, V. urceolatum, and section Pseudotinus). In two lineages each of the GBSSI paralogues is represented by two distinct sequences. The presence of additional copies appears to be correlated with polyploidy in these two clades and the placement of the homoeologues in gene trees suggests the possibility of a hybrid origin for each polyploid lineage.
