^aThe total number of transcripts for each species.
^bIn cases where two BDGPs share one BDG, then the shared BDG was counted twice in the total number of BDGs. Such BDGs are defined as redundant BDGs.
^cBecause a single gene may produce multiple BDTs, the numbers of translated unique BDGs represent BDGs corresponding to non-redundant unique BDTs
^dNew unique BDGs are BDGs identified by the modified search model but not detected by the traditional search model.
