Numbers represent percentages of nucleotides that show similarity to a repeat of the indicated category. An 'x' represents the absence of a repeat family; '0.00' indicates that the repeat is present, but at a frequency lower than 0.005 % of the nucleotides in the BESs. Species names have been abbreviated as follows: Tom.: tomato; Pot.: potato.
