This grant project is aimed to test several hypotheses explaining the controversy in the worldwide distribution pattern of angiosperm genome sizes. This project will namely revise formerly observed patterns taking in to the account phylogenetic dependence of observed characters in the design and statistical analyses of experiments, and will test possible limitation of polyploids and larger genomes in phosphorus deficient environments hypothesized
recently by Leitch & Leitch (2008) in Science. Seven careful observational and manipulative experiments are designed to test the (i) suspected negative effect large genome size across tropical, temperate and high arctic flora, and in nutrient deficiency adapted groups of carnivorous plants; (ii) phosphorus limitation of larger genomes and polyploids in local floras (subarctic Svalbard, radiating flora of Cape region); and (iii) differences in growth performances of plants with different genome sizes (including comparison of diploid and tetraploid counterparts) in deficient sites using manipulative experiments.
