  • Mean values for PI and corrected DAPI measurements are for haploid genome size and are from this study. Standard error (SE), the range (lowest and highest values), and the number of strains for each species (n) are shown. See supplemental data at http://www.genetics.org/supplemental/ for specific strain values. DAPI values for larger genomes tend to be less accurate than PI values (see text). For comparison, previously reported genome size estimates are listed in the right-most column. Methods used for determining previous estimates are biochemical analysis (BC), cytometry (CY), kinetics (KI), Feulgen densitometry (FD), and molecular weight (MW), or method unknown (UN).
