  1. * The estimated number of mutations per plant was calculated using an estimated genome size of 500 Mb for B. rapa [30]. Numbers in brackets were obtained after normalising to the average 35% GC content for the B. rapa genome [29].
  2. ** Mutation density based on estimated number of mutations per plant divided by the 500,000 kb
  3. genome. Numbers in brackets were obtained after normalising to the average 35%
  4. GC content for the B. rapa genome [29].
  5. *** The number of expected mutations per kb in the population was obtained by extrapolating the
  6. number of detected mutations in a subset of the M2 plants to the whole population.
  7. Numbers in brackets were obtained after normalising to the average 41% GC content for B. rapa
  8. exons [29].
