Percentage of nucleotides in the BESs covered by BLASTX hits to the non-redundant protein database. The BLAST hits have been divided into three categories ('coding', ' repeats', 'other') based on keyword filtering. Each category has subsequently been divided into 'masked' (i.e., overlapping with repeats identified by RepeatMasker) and 'unmasked' (i.e., no overlap with repeats identified by RepeatMasker) subcategories. Species names have been abbreviated as follows: Tom.: tomato; Pot.: potato.
