Pioneering polyploids: the impact of whole-genome duplication on biome shifting in New Zealand Coprosma (Rubiaceae) and Veronica (Plantaginaceae)

Luke Liddell, William Lee, Esther Dale, Heidi Meudt & Nick Matzke
The role of whole-genome duplication in facilitating shifts into novel biomes remains unknown. Focusing on two diverse woody plant groups in New Zealand, Coprosma (Rubiaceae) and Veronica (Plantaginaceae), we investigate how biome occupancy varies with ploidy level, and test the hypothesis that whole-genome duplication increases the rate of biome shifting. Ploidy levels and biome occupancy (forest, open, and alpine) were determined for indigenous species in both clades. The distribution of low ploidy (Coprosma: 2x, Veronica:...
