Data used in the estimation of effective population size (Ne).

aChanges per site of non-coding sequences only between Poncirus trifoliata cultivars ‘Pomeroy’, ‘Flying Dragon’ and Citrus sinensis cultivar ‘Washington’ navel orange calculated using MEGA with complete deletion of indels (indels were included as separately coded single characters).bNeutral mutation rate (changes per site per year) on the assumption that non-coding sequences are neutrally evolving and that P. trifoliata and C. sinensis diverged 5.9 Ma.cμ/20 converts the per year value into a per generation value, assuming a generation time of 20 years.dMedian estimated values using MCMCcoal with allele samples size indicated for each gene.eMRCA = most recent common ancestor.fMedian (Lower – Upper) 95th percentile range.
