Frequency of REP doublets within the SBW25 genome.

Data are the frequency of REP clusters (from doublets to cluster of 18 REPs) found in extragenic space compared to a null model based on the random assignment of 560×71 bp and 560×110 bp segments (to extragenic space). REP clusters containing an uneven number of REP sequences are included in the next lower cluster size (REP singlets are omitted).aObserved occurrences from the SBW25 genome.bExpected values (means and standard deviation) based on 10,000 simulations.cThe proportion of times the observed frequency was less than or equal to the expected value.dThe proportion of times the observed frequency was greater than or equal to the expected value.
