  1. Statistics for P. avium, P. mume, and P. persica are based on Shirasawa et al. [8], Zhang et al. [9], and The International Peach Genome Initiative [10], respectively, and repetitive sequences were recalculated using the same criterion used to annotate the P. yedoensis var. nudiflora genome
  2. aSequences encoding ribosomal RNA, transfer RNA, and microRNA were considered
