Fig. 4.

Structure of the Ping16A_Stow locus, which is associated with increased mPing copy number. a Structure of the Ping16A_Stow insertion site. The Ping16A element (green arrow) is inserted in the middle of a nonautonomous Stowaway element (red box), which is not in Nipponbare (blue bar). Nucleotides shown within the blue dotted lines are the sequences of the nonautonomous Stowaway element. Target site duplications (TSDs) are indicated by nucleotides underscored. b Comparisons of mPing copy number in 3000 rice accessions with or without Ping16A_Stow in the genome. Gray dots indicate mPing copy number of rice accessions in each category. The error bars show standard deviation (s.d.) of each category. Differences in mPing copy numbers between two categories were tested by a two-tailed Wilcoxon–Mann–Whitney test. Source data for Fig. 4b are provided in Supplementary Data 1
