Genome size variation in a polyploid complex

Whole-genome duplication, or polyploidy, is a common and repeated process in angiosperms, and contributes to variation in genome size. McIntyre assesses ploidy and genome size for 78 populations within the Claytonia perfoliata (Portulacaceae) complex, comprised of three diploid taxa with numerous polyploids that range to the decaploid level. The results suggests that higher level polyploids (hexaploids) exhibit increased variation in genome size relative to diploids, and that plants from colder environments possess larger genomes.
